E-4 Chapter 1 Safety Instructions 1 About this Manual This manual is part of the documentation for the NX8000 family of transmitters from Rohde
& Schwarz. Each transmitter and each transmitter component is described in a separate manual. The individual manuals of the family of transmitters are modular in structure and complement each other. Structure Each transmitter component is described in a separate manual and can thus be used as an individual component (where practical). The transmitter manual is the main document for the entire set of documentation. It describes all steps that are necessary to install a trans-
mitter, put it into operation, operate and maintain it. Where applicable, the transmitter man-
ual refers to the individual manuals for the various components. The component manuals, in turn, also refer to the transmitter manual whenever the component is to be used as a transmitter module. Contents The manuals for the family of transmitters describe all steps required to install the transmit-
ter or one of its components, put them into operation, operate and maintain them, trouble-
shoot and service them. The Annex includes interface descriptions plus technical documents. For convenience, all manuals are structured identically. Sections that are not relevant to the manual at hand are also included but are left blank. Safety All skilled personnel working with a transmitter or its components must read all relevant manuals and comply with the safety measures that are detailed in the chapter about safety and in the applicable sections in the manual. The transmitter and the individual transmitter components must be used only for their intended purpose. All operations involving the transmitter or individual transmitter components must be performed by skilled personnel. The manual will point out specifically if additional qualifications are required. Symbols and Layout The triangular warning symbol indicates danger. In addition to the triangular warning sym-
bol, different key words indicate the level of potential danger. Instructions are given in numbered steps or indicated by an "index finger" symbol to the left of the instruction text. The results of the performed instructions are indented. The key word "Note" precedes notes. Notes contain additional information and tips to help facilitate the work at hand. All other formatting options add structure to the text and are self-explanatory. 2098.1190.72

E-4 Chapter 1 Safety Instructions 2 Safety Instructions for Transmitter Systems and Instruments ATTENTION!
The safety instructions provided in this manual must be complied with!
Pay special attention to the following points:
Only skilled personnel may perform electrical installation and electrical connection tasks.
Always follow the relevant national and international safety rules and regulations when equipping operating areas and when setting up and operating electrical equipment. These rules and regulations include for example:
Protective measures to prevent accidents Protective measures to prevent overvoltage Insulation status of electrical equipment Grounding of electrical equipment Physical properties and laying of electric lines and cables Regulations applying to industrial premises and areas as well as to special facilities.
When setting up the rack, observe the country-specific rules for accident prevention, for example with regard to:
Risk of getting crushed when working with loads suspended in the air Risk of falling off ladders Risk of injury when lifting heavy objects.
Use your personal protective equipment for installation and repair work, i.e. wear pro-
tective clothing such as helmets, safety gloves and eye protection, depending on the task at hand.
Operate the equipment and systems only when the cabinet is closed. If you have to open the cabinet for maintenance and repair work, comply with the applicable safety instruc-
tions.
If the equipment and systems are removed from the AC power supply, all poles must be disconnected. Check for and remove any external power supply, i.e. all measuring ca-
bles, extension cables, multiple socket outlets (except for special service sockets). Wait for five minutes to ensure that any and all capacitors are sufficiently discharged.
Additionally with liquid-cooled transmitters:When filling and installing the cooling system
(pump unit and heat-exchanger unit), observe the rules for handling hazardous sub-
stances (cooling agents); see section "safety data sheets about hazardous substances"
under "EU safety data sheet in accordance with 2001/58/EC Antifrogen". 2098.1190.72

E-4 Chapter 1 Safety Instructions 3 General Safety Instructions This section contains general safety instructions that apply to all products manufactured or distributed by Rohde & Schwarz. In accordance with IEC 215 and EN 60215, transmitters and their auxiliary equipment must be operated only under the responsibility of skilled personnel. The EN 60215 standard
("Safety requirements for radio transmitting equipment") defines the minimum requirements for skilled electrical personnel. Complying with all statutory provisions is a precondition for operating radiocommunications systems and equipment. The operator or the operator's authorized representative is re-
sponsible for ensuring compliance with these guidelines. They must also ensure that the operating personnel meets the applicable country-specific training requirements. These re-

It is therefore essential to make sure that the tags described here are always used only in connection with the related product documentation and the related product. The use of tags in connection with unrelated products or documentation can result in misinterpretation and in personal injury or material damage. Operating states and operating positions The product may be operated only under the operating conditions and in the positions specified by the manufacturer, without the product's ventilation being obstructed. If the manufacturer's specifications are not observed, this can result in electric shock, fire and/or serious personal injury or death. Applicable local or national safety regulations and rules for the prevention of accidents must be observed in all work performed. 1. Unless otherwise specified, the following requirements apply to Rohde & Schwarz products:
predefined operating position is always with the housing floor facing down, IP protection 2X, pollution severity 2, overvoltage category 2, use only indoors, max. operating altitude 2000 m above sea level, max. transport altitude 4500 m above sea level. A tolerance of 10 % shall apply to the nominal voltage and 5 % to the nominal frequency. 2. Do not place the product on surfaces, vehicles, cabinets or tables that for reasons of weight or stability are unsuitable for this purpose. Always follow the manufacturer's installation instructions when installing the product and fastening it to objects or structures (e.g. walls and shelves). An installation that is not carried out as described in the product documentation could result in personal injury or death. 3. Do not place the product on heat-generating devices such as radiators or fan heaters. The ambient temperature must not exceed the maximum temperature specified in the product documentation or in the data sheet. Product overheating can cause electric shock, fire and/or serious personal injury or death. 1171.0000.42-05.00 Page 2 Basic Safety Instructions Electrical safety If the information on electrical safety is not observed either at all to the extent necessary, electric shock, fire and/or serious personal injury or death may occur. 1. Prior to switching on the product, always ensure that the nominal voltage setting on the product 2. 3. 4. matches the nominal voltage of the AC supply network. If a different voltage is to be set, the power fuse of the product may have to be changed accordingly. In the case of products of safety class I with movable power cord and connector, operation is permitted only on sockets with an earthing contact and protective earth connection. Intentionally breaking the protective earth connection either in the feed line or in the product itself is not permitted. Doing so can result in the danger of an electric shock from the product. If extension cords or connector strips are implemented, they must be checked on a regular basis to ensure that they are safe to use. If the product does not have a power switch for disconnection from the AC supply network, the plug of the connecting cable is regarded as the disconnecting device. In such cases, always ensure that the power plug is easily reachable and accessible at all times (corresponding to the length of connecting cable, approx. 2 m). Functional or electronic switches are not suitable for providing disconnection from the AC supply network. If products without power switches are integrated into racks or systems, a disconnecting device must be provided at the system level. 5. Never use the product if the power cable is damaged. Check the power cable on a regular basis to ensure that it is in proper operating condition. By taking appropriate safety measures and carefully laying the power cable, you can ensure that the cable will not be damaged and that no one can be hurt by, for example, tripping over the cable or suffering an electric shock. 6. The product may be operated only from TN/TT supply networks fused with max. 16 A (higher fuse only after consulting with the Rohde & Schwarz group of companies). 7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the socket. Otherwise, sparks that result in fire and/or injuries may occur. 8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric shocks. 9. For measurements in circuits with voltages Vrms > 30 V, suitable measures (e.g. appropriate measuring equipment, fusing, current limiting, electrical separation, insulation) should be taken to avoid any hazards. 10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial computers, comply with the IEC60950-1/EN60950-1 or IEC61010-1/EN 61010-1 standards that apply in each case. 11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the product. 12. If a product is to be permanently installed, the connection between the PE terminal on site and the product's PE conductor must be made first before any other connection is made. The product may be installed and connected only by a licensed electrician. 13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective devices, the supply circuit must be fused in such a way that anyone who has access to the product, as well as the product itself, is adequately protected from injury or damage. 1171.0000.42-05.00 Page 3 Basic Safety Instructions 14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the product. Otherwise, the person operating the product will be exposed to the danger of an electric shock. 15. Any object that is not designed to be placed in the openings of the housing must not be used for this purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries. 16. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and operating positions", item 1. Therefore, the equipment must be protected against penetration by liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product itself may be damaged, which can also lead to personal injury. 17. Never use the product under conditions in which condensation has formed or can form in or on the product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water increases the risk of electric shock. 18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such as alcohol, acetone or diluents for cellulose lacquers. Operation 1. Operating the products requires special training and intense concentration. Make sure that persons who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries or material damage may occur. It is the responsibility of the employer/operator to select suitable personnel for operating the products. 2. Before you move or transport the product, read and observe the section titled "Transport". 3. As with all industrially manufactured goods, the use of substances that induce an allergic reaction
(allergens) such as nickel cannot be generally excluded. If you develop an allergic reaction (such as a skin rash, frequent sneezing, red eyes or respiratory difficulties) when using a Rohde & Schwarz product, consult a physician immediately to determine the cause and to prevent health problems or stress. 4. Before you start processing the product mechanically and/or thermally, or before you take it apart, be sure to read and pay special attention to the section titled "Waste disposal", item 1. 5. Depending on the function, certain products such as RF radio equipment can produce an elevated level of electromagnetic radiation. Considering that unborn babies require increased protection, pregnant women must be protected by appropriate measures. Persons with pacemakers may also be exposed to risks from electromagnetic radiation. The employer/operator must evaluate workplaces where there is a special risk of exposure to radiation and, if necessary, take measures to avert the potential danger. 6. Should a fire occur, the product may release hazardous substances (gases, fluids, etc.) that can cause health problems. Therefore, suitable measures must be taken, e.g. protective masks and protective clothing must be worn. If a laser product (e.g. a CD/DVD drive) is integrated into a Rohde & Schwarz product, absolutely no other settings or functions may be used as described in the product documentation. The objective is to prevent personal injury (e.g. due to laser beams). 7. 1171.0000.42-05.00 Page 4 Basic Safety Instructions Repair and service 1. The product may be opened only by authorized, specially trained personnel. Before any work is performed on the product or before the product is opened, it must be disconnected from the AC supply network. Otherwise, personnel will be exposed to the risk of an electric shock. 2. Adjustments, replacement of parts, maintenance and repair may be performed only by electrical experts authorized by Rohde & Schwarz. Only original parts may be used for replacing parts relevant to safety (e.g. power switches, power transformers, fuses). A safety test must always be performed after parts relevant to safety have been replaced (visual inspection, PE conductor test, insulation resistance measurement, leakage current measurement, functional test). This helps ensure the continued safety of the product. Batteries and rechargeable batteries/cells If the information regarding batteries and rechargeable batteries/cells is not observed either at all or to the extent necessary, product users may be exposed to the risk of explosions, fire and/or serious personal injury, and, in some cases, death. Batteries and rechargeable batteries with alkaline electrolytes (e.g. lithium cells) must be handled in accordance with the EN 62133 standard. 1. Cells must not be taken apart or crushed. 2. Cells or batteries must not be exposed to heat or fire. Storage in direct sunlight must be avoided. Keep cells and batteries clean and dry. Clean soiled connectors using a dry, clean cloth. 3. Cells or batteries must not be short-circuited. Cells or batteries must not be stored in a box or in a drawer where they can short-circuit each other, or where they can be short-circuited by other conductive materials. Cells and batteries must not be removed from their original packaging until they are ready to be used. 4. Keep cells and batteries out of the hands of children. If a cell or a battery has been swallowed, seek medical aid immediately. 5. Cells and batteries must not be exposed to any mechanical shocks that are stronger than permitted. 6. If a cell develops a leak, the fluid must not be allowed to come into contact with the skin or eyes. If contact occurs, wash the affected area with plenty of water and seek medical aid. Improperly replacing or charging cells or batteries that contain alkaline electrolytes (e.g. lithium cells) can cause explosions. Replace cells or batteries only with the matching Rohde & Schwarz type (see parts list) in order to ensure the safety of the product. 7. 8. Cells and batteries must be recycled and kept separate from residual waste. Rechargeable batteries and normal batteries that contain lead, mercury or cadmium are hazardous waste. Observe the national regulations regarding waste disposal and recycling. Transport 1. The product may be very heavy. Therefore, the product must be handled with care.

Handles on the products are designed exclusively to enable personnel to transport the product. It is therefore not permissible to use handles to fasten the product to or on transport equipment such as cranes, fork lifts, wagons, etc. The user is responsible for securely fastening the products to or on the means of transport or lifting. Observe the safety regulations of the manufacturer of the means of transport or lifting. Noncompliance can result in personal injury or material damage. If you use the product in a vehicle, it is the sole responsibility of the driver to drive the vehicle safely and properly. The manufacturer assumes no responsibility for accidents or collisions. Never use the product in a moving vehicle if doing so could distract the driver of the vehicle. Adequately secure the product in the vehicle to prevent injuries or other damage in the event of an accident. 3. Waste disposal 1. If products or their components are mechanically and/or thermally processed in a manner that goes beyond their intended use, hazardous substances (heavy-metal dust such as lead, beryllium, nickel) may be released. For this reason, the product may only be disassembled by specially trained personnel. Improper disassembly may be hazardous to your health. National waste disposal regulations must be observed. If handling the product releases hazardous substances or fuels that must be disposed of in a special way, e.g. coolants or engine oils that must be replenished regularly, the safety instructions of the manufacturer of the hazardous substances or fuels and the applicable regional waste disposal regulations must be observed.

Appropri-
ate measures must be taken to prevent exposure to any danger when working with voltages that bear the risk of electric shock. Never work on live parts unless specifically required and only if the special safety precautions are complied with. 4.1.1 AC Power Supply
Before connecting the AC power supply, it is important to ensure that the power supply specifications given for the system or instruments match the nominal specifications for the local power supply network. The power supply circuit must be protected by means of fuses in order to prevent overloads and short-circuits.
Miniature modules have neutral conductor fuses. As a result, the power supply may still be connected even after interruption of the circuit by a fuse. It is quite possible for a transmitter to have several separate electric circuits. Each of these circuits is subject to the following requirements:
All electrical connections between the transmitter and the AC power supply must comply with the following conditions:
The transmitter can be disconnected at any time. The transmitter can be prevented from being switched back on. The transmitter is terminated with a fully protected power cable matched to the power consumption.1 Ensure that phase rotation is correct (direction of rotation of fans!). Service sockets It is common practice to equip transmitters with a connector that carries voltage even when the transmitter is turned off and that allows power to be supplied to test equipment or a sol-
dering iron. These connectors are identified, e.g. by an LED, and may only be used for the aforementioned purposes. The intended purpose of the sockets means that they have only a limited power output. The connector is not suitable for supplying power to heating equipment or large test sets.
The transmitter operator is responsible for providing the correct fuse protection (the maximum value is specified on the socket).
In the case of accessory parts that are not connected to the main transmitter, the trans-
mitter operator is responsible for taking appropriate measures to ensure that the instal-
lation is safe in the respective switching state. 1 Obtain the specifications from this documentation and also adhere to the breaking capacity limits of the fuses and circuit breakers in the transmitter. 2098.1190.72
- 1.4 -
E-4 Chapter 1 Safety Instructions 4.1.2 Replacing Fuses
Replace the safety fuses accessible in the operator area only if no voltage is being ap-
plied to the instruments. The safety fuses may be replaced only by fuses with identical electric data, identical switching characteristics and identical switch-off capacity.
Motor and line circuit breakers accessible in the transmitter's operator area may be op-
erated. If their response range is selectable, do not change the settings made by the manufacturer. If the settings are accidentally changed, reset them by using the correct values specified in this documentation. 4.1.3 Emergency-Off Equipment
If the customer requests, the transmitters are equipped with emergency keys. When the transmitters are supplied, these keys have basically no function. The transmitter opera-
tor is responsible for ensuring that these emergency keys function safely and to inte-
grate them into the emergency-off system of the operator area in accordance with the regulations. If you subsequently decide not to use the emergency keys as an emergen-
cy-off system, you must remove them.
Extremely important! A transmitter normally has several AC supply circuits that are independent from each other, such as main AC supply circuit, AC current supply for ac-
cessory equipment (main control unit, antenna switch, etc) or AC current supply for a disabled socket. The transmitter operator is responsible for making sure that all these circuits are inte-
grated correctly into the emergency-off system. Circuits not integrated have to be la-
beled accordingly.
Never set up a transmitter that is equipped with disabled emergency-off equipment. 4.1.4 Opening the Transmitter
When you open the transmitter to carry out mechanical/electrical tasks (e.g. cleaning, repair, etc) always follow the five basic rules for working with electrical systems:
Disconnect the transmitter from the power supply Secure it against inadvertent switch-on Verify safe isolation from any power Ground or short-circuit it2 Cover adjacent active circuits.
Extremely important! A transmitter normally has several AC supply circuits that are in-
dependent from each other, such as main AC supply circuit, AC current supply for ac-
cessory equipment (main control unit, antenna switch, etc) or AC current supply for a disabled socket. Prior to performing any work, check the current status of the circuits. Also disconnect adjacent circuits to prevent inadvertent contact. 2 Not all transmitter types can be grounded or short-circuited by using a grounding or short-circuit switch. If a suitable device for grounding or short-circuiting is not available, the skilled personnel must take appropriate measures as deemed necessary. 2098.1190.72

E-4 Chapter 1 Safety Instructions
If you have to perform any work on the RF circuit, isolate the antenna connector as well. Caution! If other transmitters, etc, are in operation that are coupled to the same antenna via RF filters, energy from them can be fed back via the antenna cable.
Never open a disconnected transmitter without taking protective measures against touching voltage-carrying parts.
Due to the risk of electric shock from the AC supply voltage, never perform any electrical operations when doors are open, front panels are unscrewed, plug-ins are withdrawn, etc.
When electrical operations of the transmitter are performed for the purpose of internal measurements or repair, label the workplace accordingly and provide warning about the potential hazards in accordance with the basic rules of electrical engineering. Appropriate measures have to be taken to prevent unauthorized persons from access-
ing this area. After completing your work, close the transmitter and restore all safety measures for pre-
venting electric shock that have been provided by the manufacturer. Immediately make sure that protective equipment (e.g. locks) is effective. 4.2 Hazards due to High-Energy Circuits The instruments include low-voltage circuits which can be fed from an extremely low-imped-
ance voltage source(e.g. amplifier operating voltage). These circuits conduct dangerously large amounts of energy. We handle these circuits in the same manner as circuits with volt-
ages that bear the risk of electric shock. They are usually covered and thus protected against accidental contact. The cover comes with a warning label. If you remove the cover of a transmitter that is in operation, there is the risk of both voltage poles being short-circuited. Short circuits create an electric arc and thus can cause burns, damage to the eyes as well as further injuries due to the state of shock response. Practical experience has repeatedly shown that a short circuit caused by metal tools can cause severe burns. For safety reasons, high-energy circuits are protected by covers and are thus not accessible within the operator area of the instruments.
If you need to measure low-impedance voltages, during repair work or to optimize the power consumption of the transmitter for example, exercise the same caution as when measuring operating voltages that bear the risk of electric shock. Wear protective clothing if necessary.
Before you open an instrument or remove its cover, switch off the operating voltage and wait for five minutes to ensure that any and all capacitors are sufficiently discharged.
Do not short-ciruit capacitors to discharge them. 4.3 RF Hazards 4.3.1 Mandatory Training
Operators must instruct their personnel on how to use this transmitter or instrument in accordance with EN 60215 and IEC 215. This periodic training must cover the radio-fre-
2098.1190.72
- 1.6 -
E-4 Chapter 1 Safety Instructions quency hazards of the individual transmitter or instrument. Only after such training has been provided and documented may the operating personnel handle switching and op-
erating tasks. High-energy RF circuits within the transmitter or the instrument are routed via conventional detachable RF connectors (e.g. N). Depending on the output power, the transmitter or in-
strument outputs come with screw-in or pluggable RF lines or ducts. If RF lines or modules conduct high power, the connection point or the entire module is marked with the standard warning symbol (yellow triangle with black exclamation mark). 4.3.2 RF Shielding Transmitters and instruments from Rohde & Schwarz are shielded in such a manner that RF radiation does not pose any danger even in the immediate vicinity if all RF lines are closed. This statement is based on the ordinance for electromagnetic fields as defined in German law:
The 26th ordinance for the Federal Emission Protection Law dated December 16, 1996 de-
fines limit values for radio-frequency equipment for electric and magnetic field strengths. 4.3.3 Rules for Operating the Transmitter Opening RF lines during operation may cause electric arcs. This can cause burns and eye injuries.
Operate the transmitter system only if an antenna or dummy antenna is connected.
Never undo RF lines during transmitter operation.
Never open modules during transmitter operation.
Never put transmitters into operation if RF lines are open. 3
When disconnecting a transmitter, always disconnect the antenna connector as well. If other transmitters, etc, are in operation that are coupled to the same antenna via RF fil-
ters, energy from them can be fed back via the antenna cable. 4.3.4 Rules for Working with an Open Transmitter If you switch on an open transmitter and remove covers and shielding that carry the general warning symbol of RF modules, dangerous RF levels will be radiated . The transmitter operator is responsible for strict compliance with the necessary safety pre-
cautions when someone is working with or located near an open transmitter that is switched on. Necessary safety regulations include:
3 If you try to put the transmitter into operation, RF power is transmitted. If RF lines are open, the transmitter switches off the RF again. This attempt to transmit RF can lead to the above mentioned risks of injury even if
- as is the case with Rohde & Schwarz transmitters - the RF flow is limited and transient due to technical mea-
sures. 2098.1190.72
- 1.7 -
E-4 Chapter 1 Safety Instructions
Labeling the workplace as subject to RF hazards
Wearing RF protective cloth
Taking special safety precautions for persons with implants such as metal parts, pace-
makers, etc, since they are particularly susceptible to injury. 4.4 Fire Hazards Every electric circuit containing sufficient energy and to which voltage is applied poses fire hazards. This also applies to radio transmitters. For transmitter radio systems, it is therefore necessary to create a safety plan for the event of fire. Operating personnel must be trained on how to proceed in the case of fire in areas contain-
ing electrical systems; training must be repeated at regular intervals. Personnel should be trained on the basis of the VDE 0132 standard and in agreement with the local fire depart-
ment. The following statement applies in Germany. Preventive measures at the site in question can largely eliminate the risk of fire or prevent its spread as far as possible. Prevention and fire-fighting
When setting up the transmitter, the operator must ensure that no inflammable materials are located below or above the cable entry nor attached to it. Make sure that openings to adjacent spaces are closed in a flame-retardant manner.
Fire-fighting is only allowed with special equipment even if the flames are insignificant or have no effect at all (e.g. breathing mask with air bottle).
For fire-fighting, only suitable fire extinguishers (e.g. CO2 extinguishers) may be used. One reason for requiring special equipment is the fact that extremely poisonous and imper-
ceptible carbon monoxide is released during every fire. Another reason is that the materials contained in the instruments and systems emit poisonous vapors, gases and dust such as sulfuric acid and hydrogen sulfide, hydrochloric acid, dioxin, hydrofluoric acid and beryllium oxide dust when they are exposed to external flame and heat. The following materials can be affected:
Rubber in cables, cable bushings, vibration absorbers and instrument feet PVC in cables and lines PUR (foam) in insulators, molded parts, sealing mats and insulating strips Teflon in cables, lines, insulation material and printed boards Beryllium oxide ceramics in power transistors 2098.1190.72

E-1 Chapter 2 Design and Characteristics The splitter distributes the output signal of the exciter to the individual amplifiers. In addition, an integrated attenuator that is dependent on the number of outputs ensures that the RF signal is output at the right power level. The splitter is a broadband unit that operates in the frequency range 470 MHz to 862 MHz. 1.5.2 Amplifier Fig. 22 R&S VH8300A1 amplifier The R&S VH8300A1 air-cooled amplifier operates in the broadband range from 470 MHz to 862 MHz (UHF bands IV/V) and is suitable for both analog and digital signals without needing to be adjusted. The output power of an amplifier is, depending on the requirements with regard to the MER, between 450 W und 500 W. The amplifiers amplify the exciter signals distributed by the splitter and forward them to the combiner. The amplifiers in a transmitter rack are controlled via the rack controller. Mea-
sured values and status information are recorded by the rack controller via CAN bus and forwarded to the R&S NetCCU800 transmitter control unit. The number of amplifiers in the transmitter depends on the transmit power. Note For detailed information about the amplifier, refer to the amplifier manual. Transmitters with one amplifier in rack In transmitters with only one amplifier in the rack, the splitter and combiner are omitted. The signals of the exciter are fed directly to the amplifier and, following amplification, routed fur-
ther downstream in the signal path to the harmonics filter. 1.5.3 Combiner Note This section is not relevant for transmitters having only one amplifier in the rack. 2098.0188.72

E-1 Chapter 2 Design and Characteristics Fig. 24 Absorber The absorber resistors (dummy loads) for the combiner are located on the absorber block. When the combiner is being operated in unbalanced mode (e.g. with one or more amplifiers disabled or removed) the non-combinable component of the RF power is expelled as addi-
tional heat energy via the transmitter exhaust duct. 2098.0188.72

E-1 Chapter 2 Design and Characteristics 1.6.2 Directional Couplers Fig. 26 Directional couplers The forward and reflected power is detected at the transmitter output by means of the fre-
quency-compensated directional couplers P14A (forward) and P14B (reflected). The fre-
quency-compensated directional couplers output a power-proportional DC voltage to the R&S NetCCU800 transmitter control unit via the integrated rectifier circuit. The DC voltages for forward and reflected power are displayed in the R&S NetCCU800 and also used as an S measurement for VSWR monitoring (reflection on the antenna). Directional coupler P14C is a free test point that can be used either as a forward or reflected power test point. The P14D rectifier is used in the digital TV transmitter only in combination with the ADE op-
tion. Note The transmitter is switched off due to reflection if the reflected value exceeds 2% of the for-
ward value after being checked three times. 2098.0188.72

E-1 Chapter 2 Design and Characteristics The FH 825 harmonics filter is used to suppress harmonics. It is a 23rd order Chebyshev filter which uses coaxial technology so that it is suitable for the rigid line system 13-30. On the signal path, the harmonics filter is located directly downstream of the combiner. Note The harmonics filter is varnished to reduce the surface temperature. Transmitters with one amplifier in rack In transmitters having only one amplifier in the rack, the harmonics filter is connected direct-
ly with the RF output of the amplifier via a coaxial cable. 1.8 RF Connector Fig. 29 RF connector The RF connector (1 5/8 EIA flange) is located on the transmitter roof (or under it if pre-
ferred). 2098.0188.72

E-1 Chapter 2 Design and Characteristics 1.9.1 Intake/Exhaust Air Ducts Fig. 31 Intake air duct (1) and exhaust air duct (2); here R&S NV8304 with option intake air from below The air from the intake duct is drawn in by the fans and forwarded to the distribution shaft. The distribution shaft provides enough air to each amplifier to cool it. The heated air is rout-
ed to an air collecting shaft on the opposite side of the amplifier and expelled via the ex-
haust duct. Note The intake/exhaust outputs are located either on the top or bottom of the rack, depending on your order specifications. 2098.0188.72
- 2.26 -
E-1 Chapter 2 Design and Characteristics If the intake is at the bottom, there is no intake duct. The connecting flange is then located directly beneath the fan box. If the exhaust air is directed downward, the absorber unit is situated at the bottom and feeds into the exhaust connection. 1.9.2 Fans Fig. 32 Fans A standard transmitter rack contains two fans, which adequately cool the transmitter with air. If one of the fans is defective, a warning is sent to the controller but the transmitter con-
tinues to operate. If both fans fail, the rack controller switches off the affected rack. The transmitter indicates a cooling malfunction. 2098.0188.72

E-1 Chapter 3 Installation 3 Setting Up Transmitter Make sure that the transmitter is standing in a stable position and that ventilation is suffi-
cient. Note During installation, the transmitter must be easily accessible from the front and rear. A clearance space of at least 1.2 m is necessary in order to install all components. 3.1 Preparations Before setting up and installing the transmitter, you must make the following preparations:
Check general suitability of location Prepare any openings required in the floor Set screw holes in floor for fixing the rack (optional) 3.1.1 Checking Structure, Flatness and General Suitability of Installation Surface Before installing the transmitter you must check whether the floor of the building in which the transmitter is to be operated has an adequate weight to floor-area ratio. The total weight of a transmitter rack can be as much as 385 kg when fully equipped with plug-in units. This results in a weight to floor-area ratio of at least 800 kg/m2. Note The exact weight of your transmitter is given in the specifications. The installation surface should be flat (i.e. horizontal along all axes) and measure 600 mm x 800 mm to accommodate the transmitter rack. Note During installation, the transmitter must be easily accessible from the front and rear. A clearance space of at least 1.2 m is necessary in order to install all components. Check the structure, flatness and general suitability of the chosen installation location. 3.1.2 Preparing Floor Openings (only if Feed and Return pass through Floor) If the intention is to connect cables (RF cable, control lines etc.) or intake air/exhaust air feeds from below, the appropriate floor openings need to be made in the operational build-

E-1 Chapter 3 Installation 3.2 Erecting Transmitter Rack The transmitter rack can be set up using lift equipment (crane). Lifting eyes are attached to the rack roof for this purpose. Fig. 3 Lifting eyes WARNING!
Do not stand under suspended racks, otherwise you could be crushed. Take the relevant safety precautions when climbing ladders, otherwise you could fall. 3.3 Aligning Transmitter Rack The rack must be aligned vertically and horizontally in order to prevent distortion caused by shearing forces. Use a spirit level to align the rack. Using the height-adjustable rack feet, align the rack such that it is vertical and horizontal along all axes. 3.4 Fastening the Transmitter Rack to the Floor If required the transmitter rack can be screwed to the floor or to a floor-frame. Two 12-mm boreholes are provided in the lower crossbeam of the transmitter rack for this purpose. 3.5 Removing Front Panels/Rear Panel Before you start installing the individual units, make sure that you have easy access to all units, connectors and interfaces needed. 2098.0188.72

E-1 Chapter 3 Installation 4 Ventilation System Note The ventilation system is already installed and wired inside the transmitter. 4.1 Connecting Air Intake/Exhaust Ducts The intake and exhaust air outlets are located either on the top or bottom of the transmitter rack, depending on your order specifications. The "Intake air from room" option is also avail-
able. In this case, the intake air is routed to the intake box via an integrated air filter on the rear panel. The external pressure drop must not exceed 100 Pa for the required air volume (e.g. for R&S NV8304, 4 amplifiers: 17 m2/min). As a result, a pipe system of max. 12 m in length (D = 250 mm), two 90 bends and an air filter with a drop in discharge pressure of 40 Pa can be installed. Note Always use pipes with a diameter of 250 mm. ATTENTION!
The temperature of the cooling air must not drop below the dew point, otherwise conden-
sation may occur in the air shafts. If intake air is fed in directly from outside the building, an air filter must be used. Note Be sure to connect the intake and exhaust lines properly, otherwise the system may be-
come overheated. The following drawings show the dimensioning on the top and base of the transmitter re-
quired for properly connecting the transmitter to the station. 2098.0188.72

E-1 Chapter 3 Installation 6 Amplifiers When the transmitter is delivered, one or two exciters and an R&S NetCCU800 are already mounted in the rack. The amplifiers, however, are not and must be retrofitted in the rack. 6.1 Installing Amplifiers WARNING!
Always make sure that the power supply is disconnected before commencing any installa-
tion work on the transmitter rack. This will prevent injury caused by electric shock and damage to the instruments. CAUTION!
Always have a second person assist you in installing the amplifiers as the instruments are very heavy (approx. 28 kg). Note Note Before installing the amplifier, make sure that the ventilation covers on the amplifier slots provided in the frame are open on both sides. Remove the covers if necessary. It is advisable to install the amplifiers in sequence starting at the top and working down to the bottom. Install the amplifiers as follows:
1. Carefully remove the amplifier from its packaging. 2. Select the installation position provided for the amplifier in the transmitter rack. 3. Place the amplifier on the guide rails and slide it carefully into the rack as far as it will go. The amplifier is guided onto the connections by means of guide pins on the rear panel. 4. Secure the amplifier in place using the 4 screws of the two front brackets on the rack. 5. To install additional amplifiers, repeat steps 1 to 4. Fig. 15 Installing an amplifier 2098.0188.72

E-1 Chapter 3 Installation 7 Connecting Antenna/Dummy Antenna to RF Connector The connection flanges for the antenna cables are uniformly 1 5/8 EIA for TV transmitters in the R&S NV8300 family. These flanges are located on the roof of the transmitter. Depend-
ing on the transmitter station (one or more transmitters), either the antenna (RF cable or RF transmission line) or an RF connection is connected directly to a multiple combining filter. ATTENTION!
You should not connect the antenna until you have completed all measurements. 7.1 Connecting Antenna Connect the antenna as follows:
Using the 4 screws (M8, 35 mm), secure the coaxial cable preassembled on the station to the EIA flange of the transmitter's RF output. To prevent the screw connection from loosening, insert a plain washer and a spring-lock washer. Note In regions with high humidity, the supplied rubber ring can be inserted into the groove be-
tween the two EIA flanges. 2098.0188.72

E-1 Chapter 3 Installation Fig. 16 RF connection with adapter 7.2 Connecting Dummy Antenna The dummy antenna is only connected when putting the system into operation or for main-
tenance and repair purposes. With some dummy antennas that have coolant monitoring and overtemperature monitoring, the monitoring equipment can be connected to the transmitter. The main protection loop
(X41.1 and X41.2 in the power distribution) can be used here as a temporary measure (e.g. while the unit is being put into operation). 1. To connect the main protection loop, use the inserted jumper plug and remove the jump-
er. 2. Connect the monitoring cable in place of the jumper. If you are using an RF patch panel that allows you to switch between the antenna and dum-
my antenna by means of an RF U-link connector (permanent installation), you should con-
nect the dummy antenna monitoring unit to the standby protection loop (X41.3 and X41.4 in the power distribution). This requires the patch panel messages to be additionally con-
nected to the R&S NetCCU800 transmitter control unit (X12.15 antenna message or X12.3 dummy antenna message, to X12.16 GND). Activation of the dummy antenna (via X33 in the power distribution) is then also active. 2098.0188.72

(Amplifier 1 to max. Amplifier 10). Since the numbering is derived from the chronological sequence in which the amplifiers can be detected on the CAN bus, it does not always cor-
respond to the sequence in which the amplifiers are physically arranged from top (= 1) to bottom (= n) in the rack.

E-1 Chapter 4 Commissioning 4 Precorrection This section describes the non-linear precorrection sequence in manual mode. 4.1 Functions of Nonlinear Precorrector 4.1.1 General In the basic version, the graphical user interface of the non-linear precorrector for DTV and video signals consists of the Nonlinear control panel and the FreqCorrection control pan-
el. In the case of ATV split, two further control panels are provided: Dynamic Control for the video precorrector and Nonlinear Audio for the audio signal. In combined mode an au-
dio phase precorrector is also provided for audio. 4.1.2 Linear Basic Precorrection The basic functions of the non-linear precorrector can be accessed via the Nonlinear and Nonlinear Audio control panels. Additional functions can be performed in the other control panels. Every non-linear precorrector consists of an amplitude precorrector and a phase precorrec-
tor, each independently affecting the phase distortion and amplitude distortion of the same signal. The setting of the characteristic is displayed in a graphic in which the X axis repre-
sents the instantaneous signal amplitude. The figures 0% and 100% stand for no signal am-
plitude and maximum amplitude respectively. The Y axis represent the effect and is scaled to 50 % for amplitude precorrection and 45 for phase precorrection. 50% means that at 100% amplitude the level is increased by 3 dB. Every precorrector has a series of frequency reference points which are used to model the characteristic. Frequency reference points can be user-defined, shifted in the X and Y di-
rections, be given a fixed or free slope and be deleted. In the X direction a frequency refer-
ence point can only be shifted between the two adjacent reference points. The connections between frequency reference points are computed by means of spline functions. Every characteristic consists of at least two points, one of which must be at 0% and the oth-
er at 100%. In the case of amplitude precorrection the first point is at [0%, 0%] and cannot be shifted. The second point is at 100% and can be shifted without restriction in the Y direction. A rising or falling straight line between the two points represents only an amplification or attenuation of the signal and does not create non-linear products. In the case of phase precorrection the first point is at 0% and the second point is at 100%. Both points can be shifted without restriction in the Y direction. A straight line parallel to the amplitude axis creates only a signal phase shift and does not create non-linear products. 2098.0188.72
- 4.31 -
E-1 Chapter 4 Commissioning 4.1.3 Nonlinear Frequency Responses As an additional function, the non-linear components of the DTV/video precorrection (am-
plitude or phase precorrection) can be assigned a frequency response in the FreqCorrec-
tion control panel, and the effect of the frequency response depends on the modulation. If the amplitude precorrection or phase precorrection is affected by an amplitude frequency response, only the "individual" precorrection is affected. Amplitude precorrection and phase precorrection have no influence on one another. If the amplitude precorrection or phase precorrection is affected by a phase frequency re-
sponse, part of the "individual" precorrection affects the other precorrection. The amplitude precorrection and phase precorrection therefore have an influence on one another. 4.1.4 Dynamic Precorrection (ATV Split Only) In ATV split systems, the large fluctuations in the average value of the video signal brings about temperature changes in the output-stage transistor which lead to changes in the out-
put stage characteristic as a function of the average value of the modulation. This error can be compensated for by dynamically modifying the characteristic as a function of the aver-
age signal value. 4.1.5 Audio Phase Precorrection (ATV Combined Only) In ATV combined systems, the common amplification of video and audio causes the audio signal to be affected by the video signal. This effect can be minimized with the aid of an audio phase precorrector. 4.2 General Information on Operating Precorrector The precorrector is operated by means of a web browser. The R&S NetCCU800 or exciter provides a JAVA applet which is launched by the web browser. This applet contains all of the elements needed to operate the precorrector. Note Detailed information on operating the precorrector and configuring the graphical user inter-
face can be found in the chapter "Operation" of the exciter manual. 4.3 Performing Precorrection The objective of precorrection is for the precorrector to simulate the non-linear characteris-
tic of the amplifier as accurately as possible in order to increase the linearity of the output signal. However, the precorrection limit is tied to the overload capacity of the output stage. To ob-
tain the greatest possible efficiency and lowest possible costs for a given transmitter, the output stages are set so as to achieve a transmitter output signal of the required quality. 2098.0188.72
- 4.32 -
E-1 Chapter 4 Commissioning 4.3.1 General Requirements The following requirements should be fulfilled prior to precorrection:
The transmitter must be operated at its nominal power output and the system level must be adjusted at all points. Precorrection must be on, for which the Nonlinear control panel must be selected in the precorrector graphical interface. A precorrection curve consisting of a straight line posi-
tioned on the X axis must be set for the amplitude precorrection and another for the phase precorrection. 4.3.2 Determining System Levels The graphical area contains lines representing distinctive signal levels such as all-white lev-
el (Wht), all-black level (Blk) and sync pulse level (Sync), as well as sync pulse level (Sync/
Aud) in the case of ATV combined. In DVT the level lines indicate the peak level (Peak) and the average value (Avh). These marks indicate maximum level; the actual level may be dif-
ferent. Changes to the set curve that affect only the range above the system level have no effect on the signal or on precorrection of the signal. The following method can be used to determine the actual values:
1. Use two interpolation points to determine the ends of the effective dynamic range in or-
der to define the possible setting range of the precorrector:
a) Add two interpolation points to the amplitude precorrection graph in the area above the highest mark and set their slope. You now have four points, consecutively numbered 1 to 4 from left to right. Points 2 and 3 are each indicated by an arrow. b) Shift points 3 and 4 in the positive Y direction by +50%. Point 3 should then be im-
mediately adjacent to point 2. c) Use the Write button to write this curve to the precorrector. 2. Now use the Navigator window to reduce the position of interpolation points 2 and 3 to-
gether in steps of one percent. Observe the effect:
ATV Split In ATV split systems, the first effect is seen in the sync pulse length, which can be clearly observed on the TV demodulator (sync pulse length dis-
play) or the TV analyzer. ATV Combined In ATV combined systems, the first effect is seen in the intermodulation products about the two sound carriers fTx default f(T2-T1) DTV In DTV systems the effect is seen as a reduced shoulder distance The upper of the two interpolation points thus represents the determined dynamic range limit. 3. Restore the original status. 2098.0188.72

E-1 Chapter 4 Commissioning Fig. 1 Determining system levels 4.3.3 Precorrection Procedure 4.3.3.1 Starting Precorrection Requirements The following requirements should be fulfilled prior to precorrection:
The transmitter must be operated at its nominal power output and the system level must be adjusted at all points. A spectrum analyzer must be connected to the transmitter output. Note A measurement should be taken upstream of the output filter as the shoulders are difficult to detect owing to the band limiting of the filter. When measuring signals using the spectrum analyzer, it is important to ensure that the precorrection target (e.g. 38 dB shoulder dis-
tance) is well above the noise limit, but the frequency range of the spectrum analyzer is such that no intermodulation is generated in its input section. Precorrection must be activated. In the graphics area for the amplitude and phase pre-
correction, two interpolation points are present in each graph: the first point is modula-
tion 0% with magnitude 0% or 0, and the second point is modulation 100% with magnitude 0% or 0. A DTV spectrum with clear shoulders should be visible on the analyzer. 2098.0188.72

Since phase precorrection and amplitude precorrection affect one another, repeat both precorrection procedures if necessary until the optimum result is obtained. 4.3.3.2 Phase Precorrection Proceed as follows for phase precorrection:
1. Add in a phase reference point at about 10%. This position corresponds to a lower modulation of the amplifier. 2. Shift the magnitude of the interpolation point for 100% up or down in steps of 0.5 or smaller (+ or -) until the shoulder distance on the analyzer visibly improves. 3. Keep improving the shoulder distance on the analyzer until the optimum result is ob-
tained. 4. Set another point at about 35%. 5. Shift the magnitude of the interpolation point for 10% up or down in steps of 0.5 or smaller until the shoulder distance on the analyzer visibly improves. 6. Keep shifting the magnitudes of interpolation points 2 (10%), 3 (35%) and 4 (100%) in small steps until the optimum result is obtained. Further interpolation points can be added for an optimum precorrection. The recommended number is four to a maximum of six interpolation points (including the interpolation points at 0% and 100%). If phase precorrection gives no improvement or only a minor one, the phase precorrection must be canceled and amplitude precorrection must be carried out first. Note 2098.0188.72

E-1 Chapter 4 Commissioning Fig. 3 Typical curve for starting precorrection with amplitude precorrection switched off 4.3.3.3 Amplitude Precorrection The procedure for amplitude precorrection is the same as that for phase precorrection. If the first interpolation point brings about an improvement, deal similarly with the other in-
terpolation points. 1. Set the interpolation points more or less at the positions of the phase values. 2. Set all magnitudes to zero. 3. Starting with the interpolation point for the white level (low), change the magnitude (in steps of 0.5 or smaller) in order to find the precorrection. From here on it is a prerequisite that the precorrection for phase and amplitude has been optimized at all interpolation points. Note 2098.0188.72
- 4.36 -
E-1 Chapter 4 Commissioning Fig. 4 Typical curve with both phase and amplitude precorrection switched on 4. Optimize the shoulder distance using all interpolation points again, in particular by shift-
ing the interpolation point at 100%. Keep carrying out phase precorrection and amplitude precorrection alternately until no fur-
ther improvement can be obtained. Note Further interpolation points can be added for an optimum precorrection. The recommended number is four to a maximum of six interpolation points (including the interpolation points at 0% and 100%). 4.3.3.4 Frequency-Dependent Precorrection Background The FreqCorrection control panel can be used to influence the characteristic by means of an amplitude and/or phase frequency response, the effect of which is dependent on the lev-
el. A set frequency response is applied to all signal components having a level greater than the selected threshold. On the other hand lesser signal components are unaffected. An amplitude frequency response (Amplitude Slope Amplitude 1/2 or Amplitude Slope Phase 1/2) and a phase frequency response (Phase Slope Amplitude 1/2 or Phase Slope Phase 1/2) can be applied to the amplitude characteristic and the phase characteristic in-
dependently of one another. Two independent thresholds are available (Position Point 1 or Position Point 2). The position of the thresholds (1 or 2) and their effect (A or P) are symbolically represented in the graphic. 2098.0188.72

E-1 Chapter 4 Commissioning Optimizing the shoulder distance 1. First use the the Curve Data Amplitude Read and Curve Data Phase Read buttons in the Nonlinear control panel to read off the characteristics currently set in the precorrec-
tor. The characteristics are displayed in the display part of the graphic. 2. Go to the FreqCorrection control panel. The characteristics can be seen in the graphic. 3. In the precorrector graphical user interface, switch Correction to ON and also activate Correction Point 1, Amplitude Slope Point 1 and Phase Slope Point 1. Set Position Point 1 to 5%. Fig. 5 The FreqCorrection user interface with an onset point at 5%
4. Now minimize the shoulder distance to left and right of the signal range by alternately setting the amplitude and phase regulators with the aid of the slopes of point 1. 5. Go back to the Nonlinear control panel. 6. If necessary optimize the characteristic. 7. Keep repeating steps 2, 3, 4 and 6 until the shoulder distance to left and right of the sig-
nal range reaches the required value between 37 dB and 40 dB. If necessary you must to some extent suppress the frequency dependent non-linearity in the upper level range. 2098.0188.72

E-1 Chapter 4 Commissioning 1. Set another onset point in the upper level range >25%. 2. Optimize the shoulder distance by alternately setting the amplitude and phase regula-
tors with the aid of the slopes of point 2. The slopes will then point in the opposite direction than at Point 1. Fig. 6 The FreqCorrection user interface with a second onset point 4.3.3.5 Fine Adjustment Using an Existing or Preset Characteristic If the required data is not or is no longer observed to be in an existing or factory-set precor-
rection characteristic, the precorrection does not necessarily have to be readjusted. An adjustment to the true amplifier characteristic can be obtained by changing individual interpolation points. The range with the greatest effect can be determined by slightly chang-
ing individual interpolation points. Changing the interpolation values in this range will most probably produce the desired result. Changes should be made in small steps, preferably with the aid of the Navigator window. A change must be undone if it does not result in an improvement. 2098.0188.72

E-2 Chapter 5 Operating 1 Operating Options The transmitter is controlled using the R&S NetCCU800. The R&S NetCCU800 can be op-
erated in the following ways:
Local operation via the display and menu keys on the front panel of the R&S NetCCU800 Operation via the web browser Monitoring and control via SNMP If the unit is operated via the web browser of a connected PC/client computer, two modes are possible:
Remote operation via a directly connected PC (connector on front panel) Remote control via a remotely connected network client (connector on rear panel) 1.1 Local Operation 1.1.1 Menu Keys Fig. 1 Menu operation Key MENU BACK HOME FUNCTION OK Meaning / function Starts the menu control function (activation from the system overview); calls a context menu (activation from menu) Cancels an entered value if not confirmed with OK; used to move one step back in the menu Used to return from the menu tree to the system overview. Calls a context menu for the current menu entry Confirms an entry or selection 2098.0720.72

E-2 Chapter 5 Operating Key STATUS Meaning / function Displays the system logbook (when activated from the sys-
tem overview); displays the status screen for a system com-
ponent (when activated after selecting a system component from the menu) CURSOR KEYS Used to move through the menu structure and to highlight menu elements; used to select entries 1.1.2 Operating Structure 1.1.2.1 Navigation in Menu System Note Different entry screens and menus are displayed depending on whether the R&S NetCCU800 is used as a NetCCU (transmitter control) or as an NCU/NSU (control of low-
power transmitters / control of n+1 systems). This is how you navigate within the menu system:
1. Press the MENU key. The menu is called. Note When you access the menu system for the first time, you are logged on by default under the user ID Operation which authorizes you to make settings that directly affect trans-
mitter operation. 2. Select the required menu and confirm with OK. The overview for the selected menu is then opened (here NetCCU). 2098.0720.72

E-2 Chapter 5 Operating 1.1.2.2 Selecting and Editing Entries The possibility of changing settings is controlled by a user administration facility with autho-
rization system (see the section "User Administration") and a local/remote concept which is valid for the entire transmitter. Local and Remote operating modes Local means the transmitter can be configured onsite. Local access is available via the dis-
play on the front panel of the R&S NetCCU800 or by PC via the local Ethernet port. Remote means the transmitter can be configured offsite. Remote access is available via the remote port on the transmitter. Since local and remote operation are mutually exclusive, configuration work carried out on-
site cannot collide with settings entered remotely. However, it is always possible to view transmitter settings. The Local key on the R&S NetCCU800 is used to switch between the local and remote op-
erating modes. Locked and variable settings Depending on the user rights concerned and the type of access (local or remote access) some or all processing parameters can be locked. These include restrictions arising from the actual constellation chosen. An appropriate symbol in front of the parameter value shows whether or not a parameter can be changed at this time. Symbol Meaning The present user can change the setting. A change takes effect straight away. The present user can change the setting. For the change to take effect, a restart of the R&S NetCCU800 a) (and possibly the exciter b)) must be carried out. The setting cannot be changed at the present time. Possible reasons:
The user does not have the necessary rights. c) Access is via the remote port when the R&S NetCCU800 is in local mode. Access is local when the R&S NetCCU800 is in remote mode. Setting is not possible in this constellation.
- none -
This parameter value is for a display; it cannot be set. a) To restart the R&S NetCCU800, run the Restart command in the SW Maintenance context menu. b) If the parameter identified in this way is a setting for the exciter (Exciter ..... menu path), the exciter must be restarted and then the R&S NetCCU800. To restart the exciter, run the Reboot Tx command in the Tx Setup context men (Exciter menu). c) The Info command from the context menu gives information on the necessary user rights among other things. Examples:

Detailed information about this topic can be found under http://www.wikipedia.org/. A description of the unit - the MIB (Management Information Base) - must be loaded in the central unit ("manager") from which the transmitters are monitored. A monitored unit contains a program ("agent") which can answer queries from the manager and execute commands. Furthermore, the agent may of its own accord generate a mes-
sage and send it to the manager. In this way, the central unit can be informed of a fault. 1.4.1 Installation The MIBs required for monitoring and controlling a transmitter are stored as a ZIP archive directly in the transmitter control unit and can be downloaded from there using any network-
compatible unit. All of the information required for configuration is contained in the MIBs themselves. When the transmitter is put into operation, both the agent in the transmitter and the manag-
er must be configured. Additional steps may be necessary if the transmitter is connected via routers, firewalls or similar devices as they may block data packets. The XX8000 transmitter family supports the versions SNMPv1 and SNMPv2c. Alarms can be sent as v1Traps, v2Traps or v2Informs. 2098.0720.72

E-2 Chapter 5 Operating Several destinations can be set for fault messages (alarm sinks). Several communities can be set with Read Only authorization and Read/Write authori-
zation. 1.4.1.1 Settings on Transmitter Side You can make settings yourself via the local display (if available), the web server or SNMP. The menu windows of the SNMP menu contain all the settings that are required for access-
ing a transmitter. Note Changes to these settings are adopted immediately. The device does not need to be re-
started. 2098.0720.72
- 5.22 -
E-2 Chapter 5 Operating Note Detailed information about the individual parameters can be found in the descriptions of the respective menu windows. 1.4.1.2 Settings on Manager Side To be able to monitor and control a transmitter with SNMP, the MIB of the device and a pro-
gram which can interpret the MIB must be available on the manager side. You can load all available MIBs from any device using a web browser. 1. Log on using the web browser and select the SNMP Administration menu. MIBs from Rohde&Schwarz and IRT are available. MIBs from IRT allow transmitters to be linked using SNMP irrespective of the manufacturer. They are, however, limited with respect to their functionality. When using IRT MIBs, you can select the "Inhibit Status"
for local operation (in the same way as for the parallel contacts). If this function is acti-
vated, no alarms/traps are sent when the transmitter is in local mode. You can activate/
deactivate this function using Inhibit Status in the SNMP > General menu window. The MIBs have the naming convention RS-XX8000-<TV/Radio Standard>-<Standby Concept/Option>-MIB. An example is RS-XX8000-ATV-TX-MIB for signal transmitters for analog TV. Examples of MIBs and contents:
MIB Description RS-COMMON-MIB Contains general Rohde&Schwarz definitions RS-XX8000-COM-
MON-MIB Contains definitions which all XX8000 transmitters fulfill (e.g. type plate, configuration) RS-XX8000-DVB-TX-

a) RS-COMMON-MIB b) RS-XX8000-COMMON-MIB c) MIB of the standby concept or option A detailed description of the MIBs, the information that they contain and the associated op-
tions is given below. 1.4.1.3 Testing SNMP Communication SNMP communications is properly set up if you have loaded the MIBs in your program and you are using the correct IP address of the transmitter and the correct community. For que-
ries and settings you must set the SNMP version in your manager; the transmitters detect the used protocol automatically. The following query can be used as a simple test:
In the example above, a transmitter with the IP address 10.123.10.7 queries the OID (Ob-
serialNumber jectIdentifier:
(.1.3.6.1.4.1.2566.127.1.2.167.1.1.1.2). The reply from the agent is 100111. designation unique point) data of a 2098.0720.72
- 5.24 -
E-2 Chapter 5 Operating Using a further test, you can check whether the transmitter sends an alarm message in the event of an error and whether this message reaches the alarm destinations. To do so, set an OID sendTestTrap (.1.3.6.1.4.1.2566.127.1.2.167.1.1.2.3) to the value 2, which triggers a testTrap (.1.3.6.1.4.1.2566.127.1.2.167.1.2.0.1). This alarm is sent to all receivers which have been entered for the alarms (Trapsinks, see above). This type of fault message functions in a slightly different way than that used for querying and setting values (default: UDP Port 161 for SET/GET and UDP Port 162 for alarms). The following illustration shows that the testTrap has been received correctly by the unit with the serial number 100111. Known problems If querying the data does not work or if you do not receive an alarm, check the following:

E-2 Chapter 5 Operating Has the network been connected correctly? Does the SNMP connection function exclu-
sively via the remote Ethernet interface of the device (R&S NetCCU800: X5 NETLINK, R&S Sx800/SX801: X2, R&S xLx8000: X32 ETHERNET REMOTE)?
Are the network settings (IP address, gateway) correct?
Has the correct Community been entered for accessing the manager and the transmitter
(case-sensitive)?
Is a PC firewall blocking incoming SNMP packets?
Has the program which receives alarms been started and correctly configured?
In large networks: Is a router or firewall blocking the SNMP packets?
Is message suppression (Inhibit Status in the SNMP > General menu) activated?
1.4.1.4 Configuration This chapter provides an overview of the available properties. RS-XX8000-COMMON-MIB This MIB contains general data that supports every unit:
Type plate: serial number, software version, etc SNMP configuration: table for alarm destinations and alarm versions Triggering of a test trap Counter for counting the transmitted traps List of the alarm messages last transmitted Parameters which are used in several other MIBs This information always applies to the instrument that is being monitored via SNMP. RS-XX8000-DVB-TX-MIB This MIB contains the parameters for:
the standby concepts "single transmitter", "passive exciter standby", "active output-
stage standby" and "passive output-stage standby"
all power classes (low-power, medium-power and high-power) air-cooled and liquid-cooled transmitters Different parameters are available depending on the system being queried. For example, cmdTxOpModeExcAutomatic (.1.3.6.1.4.1.2566.127.1.2.167.4.1.1.1.7) gives the reply NoSuchName if you query a single transmitter since this transmitter does not have an au-
tomatic exciter function. It is easy to find out which parameters are valid by checking the
"module compliances" (e.g. under .1.3.6.1.4.1.2566.127.1.2.167.4.5.2). Example: DVB configuration, passive exciter standby, medium power, optional DVB receiv-

This information is supplied by the internal clock of the R&S NetCCU800. If necessary, the time and date can be corrected in the Date/Time menu window. Setting item Explanation Date Used to set the current date Local Time Used to set the local time The local time is the time of day or zone time applicable at the station. Unlike universal time (UTC = universal time coordinated), there is a pos-
itive offset for time zones east of Greenwich or a negative offset for time zones west of Greenwich.This offset is determined by the time zone and is always a multiple of a full hour or sometimes of a half hour. In some countries, the clock is set forward by 1 hour in summer (daylight saving time). The time offset relative to UTC then changes correspond-
ingly. UTC Time Offset Used to enter the time offset between local time and UTC 2098.0720.72

Main + Reserve or Upper + Lower The Function of the respective parallel interface card is displayed in a box highlighted in light or dark blue. Light-blue highlight for CAN Bus A, dark-blue highlight for CAN Bus B. When a new parallel remote control interface card is installed, it is detected and displayed at a random position in the Serial number column. When more than one parallel remote control interface card is installed, it is usually necessary to identify the real card concerned. 2098.0720.72
- 5.58 -
E-2 Chapter 5 Operating To identify a card displayed in Serial number, highlight IdentifyStart in the column on the right and confirm with OK. Click the relay of the card selected, and the card can be identified via this sound. Note If the card cannot be identified in this way, a helpful alternative is to install the cards one after another and to identify each card as soon as it is installed, labeling it appropriately. Each parallel remote control interface card displayed in a random row in the Serial number column after installation must then be assigned to a function. This is done by means of the position number (No. column) in the row in which the card is displayed. 1. Double click the position number (No.) of the displayed card. 2. From the editor, select the position number of the row in which the desired function is displayed (e.g. the No. next to RemoteCtrl) and click OK to confirm. The selected parallel remote control interface card is assigned to the corresponding function (the function and card are in the same row). 2.6.5 General Purpose ParIO Menu Window In the General Purpose ParIO menu window you can control and monitor third-party equip-
ment (e.g. a generator or smoke detector) that is connected via a parallel remote control interface card. Note The window is only displayed if the use of a parallel remote control interface card for Gen-
eral Purpose ParIO in the NetCCU > Setup > NetCCU Setup > Remote Control ParIO menu is enabled. Depending on the remote control interface cards used, you now have 12 command (set) and 9 acknowledge (get) or 80 command (set) and 32 acknowledge (get) pins available. Note For technical reasons, the ratio of the available get and set ports is exactly the reverse com-
pared to remote control interface cards used for controlling transmitters. Function Link Explanation Indicator is green when the parallel remote control interface card has been identified and activated. 2098.0720.72

sages are issued if these thresholds are violated. Used to enter the nominal value, determined if necessary by external measurement of the forward power Used to select a dB value referenced to the set nominal power for for-
ward power; a fault message is issued if the actual value drops below the nominal value. RF Warning Limit Used to select a dB value referenced to the set nominal power for for-
ward power; a warning is issued if the actual value drops below the nominal value Timeout RF Fail Con-
trol Used to select the time that the lower threshold for the forward power
(specified as the RF Fail Limit) must be violated for before a fault mes-
sage is output. For example, if a value of 3 dB has been entered as the RF Fail Limit and the actual value drops below that level for 8 seconds
(typical setting for Timeout for RF Fail Control), a fault message will be output. Calibration Execution of calibration and display of the results. Gain Offset Set Gain Set Offset Internal measurement value of the nominal value Deviation from the zero value of the power display Used to calibrate the internal measurement system. Set Gain assigns the currently measured DC voltage to the nominal value for transmitter power. Used to calibrate the zero point as of which the externally measured power is displayed. Set Offset calibrates the zero point. 2.7.2 RF Probe Reflected Menu Window In the RF Probe Reflected menu window you can define the nominal values for the output power and determine the lowest level of deviation at which fault messages are to be output. Two test points are available for measuring the RF power (RF Probe Forward and RF Probe Reflection). Each test point has two RF rectifiers so that you can measure both the forward and reflected power. The reflected power is always measured using the second test point
(RF Probe Reflection). In the R&S NetCCU800 status screen, the forward power (Forward) is displayed in the left-
hand window and the reflected power (Reflection) in the right-hand window on the basis of the values entered here. 2098.0720.72

E-2 Chapter 5 Operating Display/LED Color Description Output Terminated Self Test Red Red The cable-break sensor has reported that the RF output is not terminated A hardware fault has occurred in one or more modules of the exciter; detailed information about the fault is recorded in the log-
book Temperature Red At least one module is overheating Fan Yellow A fan has failed; there is a possibility of overheating Red Both fans have failed; there is an acute risk of overheating Datarate Yellow Wrong data rate on the active input Mute Yellow Output signal from signal processing disabled Test signal Yellow Exciter is set to test mode 3.2.1 Status Displays, Warnings, and Error Messages When warnings and error messages occur, this usually means that transmission operation is impaired. Different signal colors are used to distinguish the severity of an impairment or the "quality" of the defect. The following applies:
Status display Warning green [OK]
yellow [W]
Error message red [F]
Transmission is not impaired. Although the exciter is functional, external influ-
ences may impair transmission or transmission operation. A severe error has occurred so that transmission operation is generally not possible. Note This type of LED signaling using colors and abbreviations (OK, W, F, etc) is identical for the complete menu. Indications with and without memory effect Status displays (green) and warnings (yellow) always reflect the current status of the excit-
er. On the other hand, error messages (red) remain active even after the reason for the error has passed or the error has been corrected. If the error has been corrected, you can reset the error display with the RESET key. 3.3 Logbook Menu The logbook is used to record changes in state (events) of the exciter. 2098.0720.72

E-2 Chapter 5 Operating In the first case a R&S NetCCU800 assumes control of the power amplifiers connected to the rack controller. In the case of a low-power transmitter the amplifiers are connected to the exciter, which also delivers the control signals. Each version requires slightly different setup options. These can be enabled with the aid of the Tx Mode parameter. In the case of low power, a further distinction is made between two single transmitter modes and two standby modes (see table). On delivery from the factory, the Med./High Power w. NetCCU operating mode is preset as standard. When a low-power transmitter is brought into use for the first time, its operating mode must therefore be changed. The settings do not take effect until the exciter has been rebooted.1 Note Depending on the configuration of the instruments concerned, it may no longer be possible to operate the exciter after having changed the operating mode via R&S NetCCU800 or NSU. This problem can be solved as follows:
a) Configure the operating mode appropriately in the R&S NetCCU800/NSU menu or b) correct incorrect settings via the web interface of the exciter. 3.4.2 Setup > Option Keys Submenu Certain features of the device are activated using the Option Keys mechanism. Each available software option can be enabled by installing a valid activation key. If a soft-
ware option is later no longer required, activation can be canceled again by installing a de-
activation key. Note The deactivation mechanism allows software options which are no longer required to be
"returned" to Rohde & Schwarz. Option keys are available from your local Rohde & Schwarz sales partners. Installing option keys Option keys can be installed in three ways:
Automatic installation of one or more activation keys using the Software Distributor The procedure is the same as for performing software updates (see the chapter "Main-
tenance"). Installation of an option key by means of a web browser With this method, the option key can be transferred from, for example, a received mail using the copy/paste function. Installation of an option key directly at the display With this method, a 30-digit code is entered using the keyboard. The two last methods use the installation menu Setup > Option Keys > Install described below. 1 To reboot, briefly disconnect the exciter from the AC power supply. 2098.0720.72

Display for checking the measured data rate. The maximum data pro-
cessing rate is displayed. Active Mode Displays the data format detected or set at the respective input:
ASI: As described SMTPE: As described AUTO: Auto is selected and there is no data stream 3.6.1.1 Checking Measured Data Rate By comparing the Meas. Data Rate [bps] and Req. Data Rate [bps], it is possible to check that the input buffers (FIFOs) are neither overflowing nor underflowing (both cases would result in transmission interruptions). Maximum data processing rate First, all null packets are removed from the transport stream. The associated useful data rate is measured and displayed under Measured Data Rate. Trouble-free operation is pos-
sible provided that this measurement value remains below the value for Required Data Rate. Note After the useful data rate has been measured, stuffing to the required data rate is per-
formed, i.e. the difference between Required Data Rate and Measured Data Rate is com-
pensated by inserting null packets. 2098.0720.72

E-2 Chapter 5 Operating 3.6.2 Input > Input Automatic Setting item Description Preselect Input Preselection of inputs INPUT 1: Operating input is TS 1 IN. INPUT 2: Operating input is TS 2 IN. Autoswitch Activates and deactivates automatic input switchover Priority In the event of a failure on the active operating input, automatic switcho-
ver to the standby input takes place. The automatic switchover mode is defined by the following parameter settings. Selects the priority mode EQUAL: The preselected operating input and standby input have the same priority. Once a switchover has taken place the system does not normally switch back to the previously faulty operating input. PRIO: The preselected operating input is the priority input. Once a switchover has taken place the system switches back to the prese-
lected operating input as soon as the signal reappears. Check Time Forward For setting a delay time (0 to 60 s) which must elapse before the switchover to the standby input takes place in the event of a failure on the operating input Check Time Back For setting a delay time (0 to 60 s) which must elapse before switching back to the preselected operating input after switching over from the standby input (which is no longer active) The function has no effect if the priority mode is set to EQUAL. On Input Loss For setting the behavior in the event of a defective input signal (synchro-
nization error) No Mute: The output signal is not suppressed (only effective with Mute: The output signal is suppressed if the data rate is incorrect (rec-
MFN) ommended for SFN) 2098.0720.72
- 5.83 -
E-2 Chapter 5 Operating Setting item Description Type of Loss of Input Selection:
Warning: If the input signal fails, only a warning will be generated. Fault: If the input signal fails, an additional sum fault will be generated after the time set under Fail Delay Time has elapsed. In the case of transmitters with exciter standby, switchover to the second exciter occurs. Fail Delay Time For setting a delay time which must elapse after an input signal dropout before a general fault is generated. 3.6.2.1 Automatic Input Switchover The exciter has a circuit for automatic switchover from one input to the other following a sig-
nal failure, provided that a valid signal is present at the second input. Before a failure oc-
curs, the preselected input is active. The mode of this automatic switchover circuit is defined by the following factors:
Automatic: ON or OFF (Autoswitch) Delay times until switchover (Check Time Forward and Check Time Back) Priority mode: Inputs have equal priority or the preselected input has priority (Priority) Automatic input switchover ON/OFF If automatic switchover is OFF, the preselected input remains active even if the input signal fails. If automatic switchover is ON and there is a failure at the preselected input, switchover to the associated standby input takes place. Priority mode PRIO (input priority) Following a switchover of the preselected input, the automatic system switches back to this priority input as soon as a signal reappears. Switchover is delayed for the set delay times. If the signal fails at both the operating input and the standby input, the priority input remains active. Priority mode EQUAL (equal input priority) Following a switchover of the preselected input, the standby input with the same priority re-
mains active until the input signal fails on this input also. The automatic system switches back to the preselected input, but only if a signal is present on it once again. Switchover is delayed for the set delay times. Note Selecting this operating mode keeps to a minimum the number of switchover operations and in certain cases the number of breaks in transmission (in the case of unsynchronized input streams). 2098.0720.72
- 5.84 -
E-2 Chapter 5 Operating 3.6.2.2 Behavior with Defective Input Signal The behavior in the event of a defective input signal can be influenced by the On Input Loss switch as follows:
Mute: The output signal of the exciter is suppressed as soon as synchronization with the input signal (from the operating input and standby input) is no longer possible. No Mute: The output signal of the exciter is not suppressed even though the input signal is defective. Only null packets are transmitted. 3.7 Precorrection Menu Using the menu windows in the Precorrection menu, you can activate or deactivate linear and nonlinear precorrectors individually without having to call up the precorrector GUI (see the section "Introduction to Precorrector Operation" in the chapter "Operating" of the exciter manual). If the software option "ADE" (K05) has been activated, additional functions for the automatic mode are available. The switch settings (On/Off) correspond to the related settings in the precorrector GUI. Menu windows The Precorrection menu branches to the following menu windows:

The menu windows The RF menu leads to the following menu windows:
Synthesizer: Set pilot frequency and reference frequency source Output: Used to enable the RF output, to activate output level control or set the level manually, or to correct the amplitude frequency response of subsequent components IQ Adjust: Used to adjust the modulator Limiter: Used to suppress signal peaks in the output spectrum and/or baseband 3.8.1 RF > Synthesizer 2098.0720.72
- 5.88 -
E-2 Chapter 5 Operating Setting item Explanation Frequency Reference Setting of the pilot frequency Selecting the reference source for stabilization of the frequency pro-
cessing (reference frequency source). The following settings are possi-
ble:
Internal: Operation without external reference frequency source External 5 MHz: Operation with external 5 MHz reference External 10 MHz: Operation with external 10 MHz reference External 1pps: Operation with external time reference (1 pps) The same setting options can be found in the RF > Reference menu window. OCXO Adjust Used to adjust an internal OCXO frequency (for operating mode "Inter-
nal") The same setting options can be found in the RF > Reference menu window. 3.8.1.1 Reference Frequency Source The basis for frequency generation is a 10 MHz oven-controlled crystal oscillator (OCXO). This OCXO can be operated in different modes:
"Internal" mode The OCXO runs in uncontrolled mode. It obtains its control voltage via a D/A converter which can be set using the OCXO adjust setting item. The OCXO can be adjusted via the 10 MHz MONITORING test output (front panel of exciter).
"External 5 MHz" and "External 10 MHz" modes The OCXO runs in controlled mode. Due to the control, the control voltage generated by the D/A converter is adapted on an on-
going basis so that the 10 MHz frequency of the OCXO is synchronized with the externally supplied 5 MHz or 10 MHz reference frequency.
"External 1pps" mode The OCXO runs in controlled mode. The 10 MHz frequency of the OCXO is synchronized with the external seconds pulse. In this mode, for example, SFN operation is possible without separate feed of a 10 MHz ref-
erence. 2098.0720.72
- 5.89 -
E-2 Chapter 5 Operating 3.8.1.2 Holdover Mode (if reference frequency fails) As soon as a failure of the external reference frequency is detected, the control voltage for the OCXO is no longer modified. The result of this is that the RF generation is now based on the stability of the OCXO. As soon as the external reference frequency is restored, the control voltage on the OCXO will be controlled again with the externally supplied reference frequency. 3.8.2 RF > Output Setting item Description RF Output Regulation Enables (On) or disables (Off) the RF output. Activates (On) or deactivates (Off) the output level control. During trans-
mission operation, control must be enabled. The current status of the related level adjuster is displayed as a percent-
age under RF > RF Monitor > AGC Exciter. Manual RF Level Manual setting of the output level; the setting has an effect only if output level control is deactivated. The current status of the related level adjuster is displayed as a percent-
age under RF > RF Monitor > AGC Exciter. Output Attenuation For level adaptation purposes, an integrated attenuator with a value of 3 dB, 6 dB or 9 dB can be connected. This has no influence on the level control. RF Slope Correction of a slope of the amplitude frequency response in the spec-
trum for equalizing subsequent components (output stage, filter). Modulation Slope Correction of a curvature of the amplitude frequency response in the spectrum for equalizing subsequent components (output stage, filter). 2098.0720.72

E-2 Chapter 5 Operating Display Description AGC Regulation Displays the level of the output level control 3.8.2.1 Output Level Control The output power delivered by the exciter is set to the nominal output level of 13 dBm by means of a controller. For test purposes, this controller can be deactivated. The output level is then set via the Manual RF Level control element. Note If Manual RF Level is set too low, the RF FAIL fault will be generated. 3.8.3 RF > IQ Adjust When the exciter is delivered, the I/Q modulator is factory-adjusted so that no customer in-
tervention is normally required. If a further I/Q adjustment is needed at a later time, the menu window RF > IQ Adjust offers the associated setting options. Note In the section "Maintenance" (exciter manual), you will find a description of how to perform the I/Q adjustment. The I/Q adjustment depends on the automatically selected intermediate frequency LO1. Ac-
cordingly, it applies only to the intermediate frequency displayed under LO1 Frequency. Note The following table shows the relationship between the set vision carrier frequency and in-
termediate frequency LO1:
Vision carrier frequency 47 MHz fB < 510 MHz 510 MHz fB < 580 MHz 580 MHz fB < 680 MHz 680 MHz fB < 860 MHz Intermediate frequency LO1 = 2160 MHz LO1 = 1920 MHz LO1 = 2160 MHz LO1 = 1920 MHz 2098.0720.72

E-2 Chapter 5 Operating Setting item/Dis-
plays Explanation Auto I/Q-Adjust Automatic I/Q adjustment The switch offers the following options:
Start: starts the automatic I/Q adjustment. The calculation takes approx. 1 minute. During this time (display Calc), the RF output signal is suppressed. Break: immediately stops the adjustment. The modulator must then be adjusted again in any case. Important: Before performing the I/Q adjustment, make sure that the exciter has been in operation for at least 30 minutes. During adjustment, transmitter parameters must not be changed. The values for the actuators Bias Coarse, Bias Fine, Gain and Phase determined during automatic I/Q adjustment are displayed under the setting items of the same name for manual adjustment. The values are valid only for the intermediate frequency displayed under LO1 Frequency and can, if required, be checked and optimized with a manual I/Q adjustment (see section "Adjustment of I/Q modulator"). I/Q Test Signal Switches a test signal on or off to manually perform the I/Q adjustment. Bias Coarse [I/Q]
For coarse setting and display of an actuator for suppressing the undes-
ired center carrier; setting range: -1023 to +1023 Bias Fine [I/Q]
For fine setting and display of an actuator for suppressing the undesired center carrier; setting range: -32767 to + 32767 Gain [I/Q]
Phase For setting and display of an actuator for suppressing the undesired car-
rier in the sideband; setting range: 0 to 255 For setting and display of an actuator for suppressing the undesired car-
rier in the sideband; setting range: -14 to +14 Display Explanation Auto I/Q Adjust Status display of automatic I/Q adjustment:
In Progress: an adjustment has been started; the calculation is cur-
rently being performed. Adjusted: After completion of the adjustment, the display changes from "In Progress" to "Adjusted". This status is valid until a new and automatic I/Q adjustment is carried out. The "Adjusted" display does not necessarily mean that the modulator is (currently still) adjusted. Not Adjusted: An error has occurred during the last adjustment. The automatic I/Q adjustment has to be repeated. If the automatic I/Q adjustment is still not functioning after several attempts, contact tech-
nical support. LO1 Frequency Display of the intermediate frequency LO1 which is automatically set in the modulator (1.92 GHz or 2.16 GHz) The adjustment values of the above actuators are only valid for the dis-

E-2 Chapter 5 Operating 3.8.4 RF > Limiter Setting item/display Explanation Main Limiter The main limiter suppresses signal peaks across the entire output spec-
trum of the exciter. State Level Used to activate (Enable) or deactivate (Disable) the Main Limiter Status display: Active/Off Used to set an operating point for the main limiter If 100% is set, the limiter is deactivated (like State = Off). If 0% is set, the useful signal is suppressed completely. This leads to RF Fail. Typical setting: 50%

sizer. Mute on PPS Fail For setting the behavior in SFN mode in the event of failure of the exter-
nal time reference. The following settings are possible:
off: The output signal is not suppressed. only at startup: the output signal is suppressed at startup until a valid 1 pps signal is recognized; if the 1 pps signal fails after successful synchronization, the output signal is no longer suppressed. after fail delay time: The output signal is suppressed if the 1-pps sig-
nal fails for longer than the period specified at Fail Delay Time This is the recommended setting for operation in SFN mode. Mute on Ref. Fail For setting the behavior in SFN and MFN mode in the event of failure of the external reference frequency source. The following settings are pos-
sible:
off: The output signal is not suppressed. only at startup: the output signal is suppressed at startup until a valid reference source is detected; if the reference source fails after a suc-
cessful synchronization, the output signal is no longer suppressed after fail delay time: The output signal is suppressed if the reference source fails for longer than the period specified at Fail Delay Time This is the recommended setting for operation in SFN mode. 2098.0720.72

E-2 4 Note Chapter 5 Operating Adjustment of I/Q Modulator Before performing the adjustment, make sure that the exciter has been in operation for at least 30 minutes. Objective If quadrature modulation were optimal (theoretically possible), the residual carrier would be completely suppressed. In actual practice, however, residual carriers arise (e.g. due to crosstalk). They must be suppressed using suitable correction carriers. The objective of I/Q adjustment is to suppress the undesired center carrier and undesired carrier in the sideband with respect to a test carrier by better than 60 dB. Two methods are available Two methods are available to perform the I/Q adjustment: setting and testing actuators manually or via a convenient automatic process. The automatic method will usually meet the requirements. Yet, it may sometimes be useful to test the automatically determined values for the actuators and to improve them. Note How to perform I/Q adjustment is described in the chapter "Maintenance" of your exciter manual. 2098.0720.72
