Page 4 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual III TRANSMITTER INSTALLATION III TRANSMITTER INSTALLATION To ensure long and reliable trouble free service from the UTX1KW-A transmitter, the following steps for installation are recommended. 1. MECHANICAL INSTALLATION: The UTX1KW-A was designed to be installed in a building protected from the weather. The building should have a hard surface oor such as concrete with a moisture barrier. This barrier could be pressure-treated wood sub- ooring which could be anchored to the concrete and to the transmitter to make the installation earth quake resistant. Allow a minimum of three feet around the transmitter cabinet for service access. The top of the transmitter should be clear for three feet to allow the air to exhaust from the transmitter. Air ow through the transmitter is approximately 1000 CFM. Provisions for air inlet and exhaust from the room must allow air ow with minimal obstruction. In the event that the room temperature exceeds 35 degrees Celsius, cooling air must be provided so that the room temperature will not exceed 35 degrees Celsius under worse case conditions. Notice: This equipment is HEAVY and must be handled by professional movers with proper equipment. Any damage caused by the installers is not covered under warranty. Check to ensure that installing crews have proper insurance coverage. 2. GROUNDING: Transmitter grounding is VERY IMPORTANT and must be done correctly for safety and operational reasons. A typical installation may be done as follows:

Use a heavy gauge wire such as #2 AWG strained copper or solid copper buss one inch wide by 1/8 inch thick for connections. The bonding between the transmitter and the ground rods must be good quality and protected from corrosion. The ground wires should run over the oor and connected to the ground rods located outside the building. The wire should not go through the concrete oor but over and around it. 3. AC WIRING: A ten foot cable has been provided with the transmitter to facilitate the connection to the AC Main power source. Connections to the AC Main should be made as follows:

RED AND BLACK WIRES are connected to the 220 VAC terminals WHITE WIRE is connected to the NEUTRAL terminal GREEN WIRE is connected to the SAFETY GROUND NOTICE: All wiring of this type must be done by A QUALIFIED ELECTRICIAN and must conform to LOCAL and NATIONAL Wiring CODES. Consult with your electrician to ensure that the proper breaker size is selected for the main circuit. 4. ANTENNA CONNECTION: The transmitter is equipped with a 7/8 EIA Flange connector located at the top of the rack. Conditions vary from site to site so some engineering may be required to ensure that the antenna is receiving the correct amount of power to comply with FCC licenses and to ensure safety from lightning etc. Page 5 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual IV TRANSMITTER TURN-ON PROCEDURE IV TRANSMITTER TURN-ON PROCEDURE Before applying AC Power to the transmitter for initial turn on and check out, the installation should be approved by a quali ed broadcast engineer. The turn-on procedure that follows is recommended by Pineapple Technology Inc. engineering staff:

1. Check transmitter load or antenna for proper installation and connection to the transmitter. 2. Open the transmitter and inspect all cables and wires for lose connections or broken wires in the rack assembly 3. Check for damage to the equipment mounted in the rack. 4. Check all AC breakers and on/off switches to ensure that all are OFF. 5. TURN ON THE MAIN AC BREAKER LOCATED IN THE SUB-PANEL WHERE THE AC POWER CORD WAS CONNECTED. 6. TURN ON THE MAIN AC BREAKER LOCATED ON THE ACDIS1 POWER DISTRIBUTION PANEL LOCATED ON THE FRONT OF THE TRANSMITTER. A GREEN LIGHT SHOULD COME ONE INDICATING POWER IS ON. 7. TURN ON THE AC SWITCH LOCATED ON THE FRONT OF THE ADP1000. THE INDICAT-

ING LIGHTS SHOULD BE ON AND READY FOR OPERATION 8. TURN ON THE AUX BREAKER LOCATED ON THE ACDIS1 FRONT PANEL. THE PA FANS AND THE RACK EXHAUST FANS SHOULD COME ON. 9. TURN ON THE POWER SUPPLY BREAKERS LOCATED ON THE FRONT OF THE ACDIS1. CHECK THE RR6000 POWER MODULES (2) EACH TO SEE IF THE GREEN LIGHTS ARE INDICATING NORMAL OPERATION. 10. USING THE ADP1000, CHECK THE IDLING CURRENTS ON EACH PA TO ENSURE THAT THE CURRENTS ARE IN THE CORRECT RANGE. TYPICAL RANGE IS 1.5 TO 2.5 AMPS. SEE ADP1000 OPERATING SECTION FOR DETAILS 11. TURN ON THE DRV100 DRIVER AMPLIFIER. THE GREEN LIGHT SHOULD COME ON. NOTICE: The Modulator/Upconverter has been set at the factory so that the output power indication on the ADP100 will show 100% or 1 KW p-sync power level. It is important to read the instruction manual supplied with the modulator to locate key adjustment devices on the front panel. The output level adjustment will be necessary for the next step in the turn on procedure. 12. Locate the level adjustment on the modulator/upconverter and turn the level down to minimum or CCW. 13. Turn on the power switch located on the modulator rear panel. 14. Apply a video signal (1 volt P-P) to the video input terminal Page 6 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual IV TRANSMITTER TURN-ON PROCEDURE 15. Slowly increase the output level adjustment while watching the RF Output level on the ADP1000. When the output gets up to 50% indicated power stop the adjustments. 16. Using the ADP1000 re ected power indication check the LOAD re ected power. This should be less that 5% re ected. 17. Return to the PA current readings on the ADP1000 to verify that all the currents are approximately the same. 18. With successful performance through step 17, the transmitter output power can be increased using the output level adjustment on the modulator to achieve 100%. The aural power can be added at this time not exceeding 10% of output p-sync power as indicated on the ADP1000. Page 7 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual V THEORY OF OPERATION V THEORY OF OPERATION A. INTRODUCTION The UTX1KW-A transmitter was designed to meet or exceed all FCC applicable speci cations for TV Broadcast Equipment. Special attention was given to the selection of sub-assemblies and components to achieve maximum reliability and minimum down time. The construction of the UTX1KW-A is BASIC and MODULAR with most components eld replaceable. Special emphasis was placed on KEEPING IT SIMPLE and returning to more traditional transmitter layouts and instrumentation. This transmitter was designed for Analog (NTSC) transmission with provisions and options available to convert to Digital Service when necessary. Refer to the UTX1KW-A block diagram gure 1 (page 9) for an overview of the transmitter architecture. This will give the technician basic information needed to understand the operations of the transmitter and the function of each subassembly. SEE SECTION VI.A (Page 15) FOR PARTS LIST Page 8 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual UTX1KW Block Diagram ( gure 1) V THEORY OF OPERATION Page 9 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual V THEORY OF OPERATION B. ACDIS1 AC & DC DISTRIBUTION The ACDIS1 is the primary AC power inlet module. The UTX1KW-A transmitter was designed to accept 208 to 240 V AC using a four (4) wire connection. The four wires are:

2 wires for 208-240 V AC 1 wire for neutral connection 1 wire for safety ground connection CAUTION: Connection to the AC Primary Source must be made using all four wires listed above. Follow the wiring instruction given in the AC WIRING section III.3 (Page 5). If not followed, severe damage to the transmitter and or electrical shock is possible. The ACDIS1 performs the following functions:

1. 2. 3. Provides a primary AC power breaker point to shutdown the transmitter. Provides 220 VAC power to the each of the 2 KW DC power supplies with individual breaker points for added safety. Provides 110 VAC circuits for Modulator, ADP1000, ABS (auxilary power source for remote control), and AUX Power where needed. 4. Analog metering is provided to monitor the Power Supply voltage and current being applied to the RF Ampli er stages 5. Power supply current sharing test points are provided for checking current sharing between Power Supply modules. SEE SECTION VI.B (Page 16) FOR SCHEMATIC AND PARTS LIST C. RR6000 POWER SUPPLY The UTX1KW-A transmitter is designed with over 4 KW of DC power available to the transmitter. To achieve this level, the power supply is made up of two RR6000 power modules mounted into a main frame assembly which is capable of managing three 2 KW modules. This transmitter can be ordered with a spare supply module included in the unused port for a backup. The power modules are HOT PLUGGABLE or can be removed and installed without turning off the transmitter. If the third module is installed, removing a module will not affect the performance of the transmitter. Each power supply modules has OVER VOLTAGE, OVER CURRENT, AND OVER TEMPERATURE protection as well as a fault signal in the event of a failure. REFER TO MANUFACTURERS MANUAL PROVIDED WITH THE UTX1KW-A. D. ADP1000 PERFORMANCE MONITOR The ADP1000 (PERFORMANCE MONITOR) provides the following functions:

1. Monitors FORWARD AND REFLECTED POWER to the antenna and presents it as a percentage of power rating. The transmitter comes set to 100% P-Sync power based on the ratings of the transmitter. Page 10 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual V THEORY OF OPERATION 2. Monitors Aural Power as a percentage of P-Sync rating (5-10 % typical). 3. 4. Provides a HIGH ANTENNA VSWR MONITOR in the event of an antenna or coax failure where the re ected power exceeds 25% the transmitter will shutdown. Front panel LED will change from green to red in case of a fault. Provides current monitoring of all the pallets used in the two U600LDV2 power ampli er assem-

blies. The current levels can be read directly from the multi-meter on the front panel. Individual pallets are selectable. In normal operations, a PA FAULT is indicated by going from green to red. RED indicates that the current level is below 500 ma and a transistor could have failed. To read the actual current, select the appropriate PA Bank A1 or A2 where the fault is located and select the PA with the selector switch. The multi-meter will read the actual current. 5. A PA INHIBIT switch is provided for failure diagnostic purposes. When activated, this switch allows the technician to monitor the bias currents for each pallet. These readings should be recorded when the transmitter is rst installed and used as a reference. This is the best way to trouble shoot possible transistor failures. When in the PA INHIBIT mode, the RF PWR OFF LED will change from green to red indicating that the SHUTDOWN LINE is at a TTL 0 state and the output power has been reduced to near zero. 6. An RF MONITOR port (BNC) is available to connect a spectrum analyzer for monitoring the output signal. THE METER SELECTOR SWITCHES A1 and A2 switches will select one of the two U600LDV2 ampli ers located in the MFA1KW. A1 is the ampli er located in the left slot and A2 is located in the right slot when viewed from the front panel. The Rotor Switch is the detail selector for the multi-meter. The various positions are de ned as follows:

PA1 THROUGH PA5 Reads PA pallet currents as selected Typical reading in INHIBIT MODE 1.5 TO 2 A Typical reading SMPTE BARS 5-7 A for PA1 through PA4 Typical reading SMPTE BARS 2-3 A for PA5 PA6 PS VOLTS P FWRD P RFLD P AURAL NO CONNECTION Reads DC Voltage applied to PA Stages Typical reading would be +29 to 32 VDC Reads PA output power in P-Sync percentage of rating. Full power reading would be 100%

Reads PA output power being returned from the load and displayed as a percentage of forward power. Typical reading would be < 5% indicated. Reads the AURAL POWER component as a percentage of forward power. Typical reading would be 10%

UTX1KW-A Operating and Service Manual VII ROUTINE MAINTENANCE VII ROUTINE MAINTENANCE The following KEY MAINTENANCE AND PERFORMANCE CHECKS should be made monthly or more frequently in some environments:

TRANSMITTER Remove and clean the air lters with a light detergent and dry completely before re-installing. Dirty lters will cause PA amps to shutdown resulting in a loss of RF Power. Spare lters are available from Pineapple Technology, Inc. Request PN: 990199. Check and record the voltage and current meter readings on the ACDIS1 (AC AND DC DISTRIBUTION UNIT LOCATED NEAR THE POWER SUPPLIES). NOTE: current readings will vary with picture content, therefore a standard test such as SMPTE BARS should be used. Using the ADP1000 record the bias level settings on each PA Pallet by selecting the appropriate PA with the selector switch. To make this measurement of BIAS ONLY it is necessary to activate the PA INHIBIT switch momentarily for each reading. Using the ADP1000 check and record the RF Output power level to ensure that it is still reading 100% +/-

10% from the previous settings. Using the ADP1000 check and record the VSWR (Re ected power) to ensure that it is still reading only a few percent indicating normal load operations. Using the ADP1000 check and record Aural power readings. This is normally set at 10% of P-sync. Expect this to vary only a few percent from reading to reading. Carefully inspect RF Output coax and coaxial ttings for excessive heating or discoloration. Check DC power connections on shunt and power supplies for over heating and tighten as needed. Check DC connections on PA rear panel. FACILITIES Clean all air inlet lters and exhaust outlets to ensure that the transmitter is getting clean unobstructed air ow. Perform recommended service on air condition systems. Rodent traps or baits should be renewed to keep the facilities clear of these pest which can cause sever damage Page 50 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual VIII ADJUSTMENTS AND TUNING to transmitters. VIII ADJUSTMENTS AND TUNING The UTX1KW-A is basically an FCC Type Certi ed broadband transmitter with a few frequency selective sub-assemblies:

A. MODULATOR Instructions for making adjustments to the modulator are included in the Manu-

factures Instruction Manual B. BPU1KW Band Pass lter comes adjusted to the channel as purchased. To change frequency would require a tuning adjustment to the lter. To perform this adjustment it is necessary to use a NETWORK ANALYZER and a signal generator with necessary I/O Adaptors to connect to the lter. The Technician performing this adjustment should be skilled in tuning Band Pass Filters. If the target frequency is outside of the tuning range of the lter, it becomes necessary to purchase a new lter. Replacement lters and service is available from Pineapple Technology Inc. C. U600LDV2 POWER AMPLIFIER MODULE The U600LDV2 has three areas where adjustments may be necessary over time or in the event of a frequency change. These areas are:

1. Bias adjustments: The LDMOS FET devices used in these pallet ampli ers are set to 500ma/device side or a total of 1 amp/device. This adjustment can be made on the bench by rst terminating the input and output with 50 ohm terminations. Apply 31 volts DC to the PA using a power supply that can provide a minimum of 15 amps. Note: a cooling fan will be necessary to cool the ampli er during this adjustment. To adjust biases it is best to turn all the bias adjust resistors CCW or to minimum on the pallet being adjusted. Using a clamp on AMP Meter connected to the DC Feed terminal located on the DC ISOLATION AND CURRENT MONITOR BOARD measure the current levels. The rst resistor is increased to 500ma indicated on the Amp meter. Repeat this adjustment for each additional resistor for reading of 1.0 A, 1.5 A, and 2.0 A. This will indicate that each device half is set to 500 ma. This concludes the bias adjustment procedure. This adjustment should be made at any time when a device has to be replaced. Normal bias ranges from 1.5 amps to 2.3 amps per pallet as indicated on the ADP500/1000. DO NOT USE THE ADP500/1000 CURRENT READINGS FOR MAKING BIAS ADJUSTMENTS. 2. PA PALLET RF Circuit Tuning: These circuits are Broadband and Fixed tuned providing no adjustments. Any tuning at this level is performed by the factory. 3. GAIN & PHASE MATCHING: Each U600LDV2 comes with a circuit for making Gain and Page 51 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual VIII ADJUSTMENTS AND TUNING Phase adjustments. This adjustment is xed tuned for the channel of this transmitter. Adjustment to this circuits requires the following equipment:

HP 8508A VECTOR VOLTMETER BIRD THROUGH LINE WATT METER SPLITTER 2 ea. DIRECTIONAL COUPLERS 2 ea. 500 watt terminations Component selection charts for resistors Component selection chart for capacitors Component selection charts and setup block diagram provided as needed. Recommended tuning should be within +/- 0.15 dB and +/- 3 degrees as measured on the HP 8508A. D. PHASE MATCHED CABLES The cables used to connect the splitter to the PA Ampli er inputs and those provided to connect the PA Ampli ers to the combiner are phase matched. If a cable is damaged and needs to be replaced, additional cables are available from Pineapple Technology Inc. The customer may manufacture additional cables, however the same coax type with the same connector types should be used. The phase matching procedure listed above may be used for adjusting the lengths. Matching should be within +/- 2 degrees. E. ADP500/1000 WATT METER This unit comes calibrated from the factory for the rated power level of the transmitter. Adjustments are not recommended in the eld. Page 52 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual IX PROBLEM SOLVING/TROUBLE SHOOTING IX PROBLEM SOLVING/TROUBLE SHOOTING The UTX1KW-A is a complex assembly of Digital and Analog circuits and in many cases it is advisable to contact Pineapple Technology Inc. for assistance. If it is necessary to perform eld service on the transmitter, most parts are available from Pineapple Technology, Inc. for next day shipment. The failure analysis of the transmitter starts off with the following assumptions:

A. The transmitter is connected to an AC Source which is within the speci ed voltage range and has ample power to run the transmitter. This would normally be 208-240 V AC with a minimum of 30 Amps available. B. The antenna has been checked out and veri ed to have a VSWR of 1.2:1 or better. C. The room temperature is < 35 degrees Celsius. D. There are no restrictions on the air ow in or out of the building E. The video and aural signals to the Modulator, comply with stated speci cations. CHECKING THE WARNING LIGHTS A. MFA1KW: This unit has dual performance indicator lights located above the air inlets. One set of lights for each PA Assembly located inside the unit. HS OVER TEMP

+28 VDC FAN SUPPLY GREEN RED GREEN RED GREEN RED NORMAL FAULT NORMAL FAULT NORMAL FAULT HS OVER TEMP FAULT could indicate one of the following problems:

a. Room temperature too high and the Heat Sinks are over heating b. High VSWR on PA output port will cause the Dump Load sensor to Fault. c. Air lters are dirty and need to be cleaned d. Exhaust fan failure. (located in the top of the rack)

+28 VDC FAULT could indicate a power supply failure. Check the ADP1000 for PA voltage and current readings. The power supply modules will also indicate a loss of power. FAN FAULT indications could mean that the PA blower has failed or there has been a loss of AC power to the fan. There is also a fuse located just inside of the front panel in case there is a locked rotor condition. To access the fuse, the MFA1KW must be removed from the rack and the top cover removed. This is a 5 AMP 3 AG type fuse. Page 53 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual IX PROBLEM SOLVING/TROUBLE SHOOTING B. ADP1000: There are a number of fault indicator lights on this unit that can be used for trouble shooting possible problems with the transmitter. With normal operating conditions, all the LEDs located on the front panel should be green. Red lights could indicate a fault in normal operations of the transmitter. Fault indicators are listed below;

1. ANT VSWR HIGH light is RED. This indicates that the antenna re ected power exceeds the set point in the equipment which is normally set to 25%. When this LED is on, the transmitter shutdown line is pulled down to ZERO and the transmitter RF PWR OFF LED will also light RED indicating that the transmitter has been shutdown at the driver level. This condition will automatically reset when the problem is corrected. CHECK THE ANTENNA FOR POSSIBLE FAULTS. 2. RF PWR OFF light is RED. This will occur anytime the SHUTDOWN LINE is pulled to ZERO. This control line is pulled to ZERO with any of the following faults:

a. ANT VSWR HIGH b. PA INHIBIT SWITCH IN THE INHIBIT MODE NOTICE: ONLY THE PA INHIBIT SWITCH OR THE ANT VSWR HIGH WILL SHUT-

DOWN THE TRANSMITTER DRIVE CAUSING THE RF OUTPUT TO FALL TO NEAR ZERO. 3. PA1 THROUGH PA5 LEDs RED would indicate that the PA Pallet current level has fallen below the set point and could indicate a transistor failure. The normal current with the inhibit switch activated is 500 ma. C. RR6000 POWER SUPPLY MODULES: The Power Supply module has two warning lights located on the front panel. Normally these lights are GREEN indicating that the AC Line voltage and the Over Voltage circuits are within their normal range. Should either one go out of range, the lights will turn RED and the power supply module will shutdown. This will reduce the available power to the RF Stages and could result in lower RF Output Power from the transmitter. If this happens, turn off the transmitter for about 1 minute and then turn it back on. If this warning continues, the module should be removed from the rack and returned for service and a spare module should be installed to maintain normal operations. NOTICE: Normally removing one power supply module will result in a reduction of output power if the spare module is not installed. To continue operating the transmitter the RF Drive level will have to be reduced to a level where the working supply can carry the load of two PA Assemblies. Reduce the RF drive level to a point where the power supply voltage meter is reading approximately 31 VDC. If the RF drive level is too high, this will cause the power supply to go into current limit and the voltage reading will drop. The RF Output power of the transmitter will be reduced Page 54 PINEAPPLE TECHNOLOGY, INC. UTX1KW-A Operating and Service Manual X WARRANTY by 3 to 4 dB.
