STRATA TX System Analog + Digital Portable 3.4 to 13.25 GHz Microwave Transmitter Manual Part No. 400504-1 Rev. C February 2007 Operators Guide Note To User - RF Exposure MPE Calculation RF Exposure Microwave Radio Communications (MRC) provides this warning for safety purposes with the intent to inform the user of the potential hazard to RF exposure. The following guidelines for safe operation were derived from OET bulletin 65, August 1997, as recommended by the Federal Communications Commission

(FCC). The 6.4 - 7.125 GHz STRATA transmitter is a mobile transmitter designed to provide services to broadcast ENG users under CFR 74 subpart F and 74.601 TV pickup stations. This unit, operated without an antenna, will not create RF energy exceeding 1.0 mW/cm2, the FCC limit for exposure. Once connected to an antenna, the potential for harmful exposure will be greatly enhanced. In this situation, a certain distance from the radiator is to be maintained. Calculations need to be performed to understand what that safe margin for exposure is. This is known as the Maximum Permissible Exposure (MPE) limit. Calculations provided are for common antennas often utilized in the ENG environment. The following formula used is that suggested by OET 65. Calculating MPE S=

PG (or EIRP) 4R2 EIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * P P = RF power delivered to the antenna in mW G = Power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna in centimeters S = MPE in mW/cm (milliwatts per square centimeters) Conversions dBi to numeric gain = Antilog (dBi/10) Feet to centimeters = Feet * 30.48 Centimeters to Feet = cm * .0328 4 = 12.57 User Input RF power delivered to the antenna = Watts Antenna gain (referenced to isotropic antenna) = dBi Distance from the center of radiation = Feet Calculation steps:

[S] Divide (R * 4) into EIRP S = Power Density in milliwatts per square centimeters. Note:

At frequencies above 1500 MHz, S must not be greater than 1 Reference FCC OET Bulletin 65, August 1997 - Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields Figure 1 and Figure 2 show the maximum exposure distance for various antennas. One plot provides the maximum permissible output of the STRATA transmitter for analog modulation, and the other plot for digital modulation. MRC, in accordance with the requirements set forth by the FCC, provides this information as a guide to the user. It is assumed that the users of this equipment are licensed and qualified to operate the equipment per the guidelines and recommendations contained within the product user guides and in accordance with any FCC rules that may apply.

Remote Control Options 2.2.4 For portable mobile or airborne operations, the STRATA TX System may be controlled by one of two models of Remote Control Panels. The Remote Control Panels are mounted in mobile racks or aircraft instrument panels and are connected via an RS-232 cable between the Remote Control Panel and the STRATA TX System. Antenna and Power Options 2.2.5 The flexible architecture of the STRATA TX System allows a number of options for both the transmit antenna and the power. Antenna Options The STRATA TX System is fully compatible with the MRC family of transmit antennas, including:

OmniPole omnidirectional

Megahorn compact horn

SectorScan flat panel

MicroScan parabolic

Ellipse parabolic Contact your Sales Representative to explore the wide array of antenna choices available. CAUTION To prevent damage to your STRATA TX System, MRC recommends using a +28 VDC power supply. Do not exceed +36 VDC input power or damage will occur. STRATA TX Operators Guide/Tech Ref Manual Product Description 2-3 Power Options The STRATA TX System configurations operate on +28 VDC power, supplied externally. This DC power can be supplied by the optional STRATA ACU, or from another DC power source. Contact your Sales Representative for the latest details. Note A TCU and TXU are defined as being co-located when the TXU and TCU are physically separated by not greater than 6 feet. If the TXU and TCU are co-located, power must be supplied to each unit through their individual power connectors from the same power source. See Figure 2-2. Do not use DC on coax to power the TXU or TCU when the units are co-located. Figure 2-2: Powering the TXU and TCU Independently Refer to the Installation Chapter on page 6-1 (part of the STRATA TX Technical Reference Manual only) for additional information. For those applications that use a TCU in a standalone mode, i.e., to generate ASI or DVB-S signals, DC power from the TCU to the TXU or from the TXU to the TCU cannot be used. Figure 2-3: Powering the TXU from the TCU STRATA TXU Coax Up to 600 ft.

(180 m) STRATA TCU Power Cable DC Power (+28 V) STRATA TXU STRATA TCU Branched Power Cable DC Power (+28 V) If your installation calls for separating the TXU and TCU, the TXU is powered by DC supplied by the TCU or the TCU is powered by DC supplied by the TXU. The DC power is superimposed on the coaxial cable connected between the units. See Figure 2-3 and Figure 2-4. The DC input voltage to the unit co-located with the DC power supply must be greater than +24 VDC. Figure 2-4: Powering the TCU from the TXU STRATA TXU Coax Up to 600 ft.

(180 m) STRATA TCU DC Power (+28 V ) STRATA TX Operators Guide/Tech Ref Manual Product Description 2-4 DC power superimposed on the coaxial cable between a TCU and a TXU can be supplied from either the TCU or TXU, depending upon the location of the DC power supply. Coaxial cable length/voltage limitations exist when powering from either the TXU or TCU. These limitations are based on cable size, DC voltage input, cable resistance, and cable length. A maximum length of 600 feet (180 meters) between the TXU and TCU is supported. Contact MRC Technical Support for more information on cable requirements. DC power required for a STRATA TX System depends upon the TX System configuration, i.e., if the TXU or TCU are operated in a standalone mode, if the TXU and TCU are co-located, or if the TXU and TCU are mounted in separate locations. See Figure 2-

5 on page 2-6 for the various STRATA TX System configurations available. For TX Systems that use DC power sources other than a STRATA ACU, contact MRC Technical Support for additional power information. 2.2.6 Mounting and Deployment Options The STRATA TX offers a number of options for either mobile or portable applications. For more details on installation of the STRATA TX in various applications, see the Installation Chapter on page 6-1 (part of the STRATA TX Technical Reference Manual only). Mobile Installation For mobile applications such as in a vehicle or in an aircraft, the STRATA TX System is usually mounted in an MRC fixed mounting bracket and is installed in a bulkhead or compartment. The cabling is permanently installed and power comes from aircraft or vehicle power. Portable Deployment In portable applications, the STRATA TX System will be moved from place to place and set up each time. The TXU and TCU will usually be mounted in a MRC universal mounting bracket. The bracket is attached to a tripod using a mounting plate and quick release. The cabling between the TXU and TCU is typically left in place and the power, antenna, and audio/video connections are removed at the end of each deployment. System Integration 2.2.7 System Communication When the TXU and TCU are connected, they automatically communicate via signals superimposed on the coaxial cable between the two units. This allows them to share information on installed hardware, preset configurations, current status, and alarms. System Operation Once the TXU and TCU are connected and communicating, the units work seamlessly together. System settings can be selected and modified from the front panel of either unit, regardless of which unit holds the hardware being configured. System Configuration The STRATA TX System offers two levels of system configuration, designed to match the needs of different personnel. For the field operator, the STRATA TX System has up to 9 Presets that can be selected from the front panel. Each Preset controls key parameters such as modulation, frequency, and audio and video settings. Additional settings that are front panel-

controlled include band, channel, offset, and filtering. For the advanced operator and technical staff, the STRATA TX Configurator software allows complete control of all parameters in the STRATA TX System. The STRATA TX Configurator software runs on a Windows-based PC and connects to either the TXU or the TCU via an RS-232 serial interface cable. STRATA TX Operators Guide/Tech Ref Manual Product Description 2-5 Interfacing a PC to either the TXU or TCU in a connected system gives you complete control of both units. You can read the current settings, program new settings, or return the units to their factory default settings. The STRATA TX Configurator software Figure 2-5: STRATA TX System Options automatically detects what hardware is installed in the system and assigns the appropriate configuration to the correct hardware, regardless of which unit holds the hardware being configured. 70 MHz IF Output Only NTSC or PAL Analog Video with 4 Audio Channels Available TXU RF/IF Only TXU FMT Option HPU

STRATA TXU

STRATA TCU

STRATA ACU

STRATA Remote Control Panels For details on connections between the STRATA TX System components, refer to the Installation chapter (part of the STRATA TX Technical Reference Manual only). STRATA TXU 2.3.1 The TXU (See Figure 2-6) always contains an IF/RF module that accepts either a 70 MHz COFDM, FMT IF, or external 70 MHz input signal and up-converts these signals to the required RF band. The RF frequency synthesizer circuit included in the IF/RF unit, in conjunction with the command and control power supply module, provides the means to channelize RF video and audio signals in the TX System RF band. The TXU, with either an analog (FMT) or digital (MPEG/COFDM) module, is integrated in the same housing as the HPU components. This provides the ability to incorporate high RF power output (12 watts of saturated RF power) into a single analog or digital transmitter assembly. Standard U.S. FCC band plans, as well as customer-created channel plans, may be customized using the STRATA TX Configurator software. Figure 2-6: STRATA TXU As noted previously, the TXU may also include either an MPEG/

CODFM or FMT module (but not both), in which case the TXU serves as a stand-alone digital or analog video microwave transmission system. STRATA TCU 2.3.2 The TCU (See Figure 2-7 on page 2-8) may contain either analog or digital or both analog and digital video modulation modules. Where an application might initially employ only analog video transmission but expects to migrate to dual, switchable, analog and digital operation, the TCU may be upgraded to add the MPEG/COFDM module to add this capability. STRATA TX Operators Guide/Tech Ref Manual Product Description 2-7 Figure 2-7: STRATA TCU Figure 2-8: AC to DC Converter

DCDC OUTPUT OUTPUT Where only digital or analog video transmission is desired, the MPEG/COFDM or FMT modules may be installed in a TXU, thereby eliminating the need for a TCU. The STRATA TX design does not permit splitting digital and analog video modulator modules between a TXU and a TCU. A TCU may also consist of a stand-alone configuration whereby either or both MPEG/COFDM and FMT modules may be used independent of the TXU. This configuration permits use of a TCU equipped with analog and/or digital video modulation modules for a variety of signal input and output configurations, including a digital option using NTSC or PAL composite video input and ASI

(digital) signal output. STRATA ACU 2.3.3 For fixed or portable deployment applications, the STRATA TX System may be powered by the optional AC to DC Converter

(ACU). See Figure 2-8. The ACU installs as part of an integrated stack for either tripod or fixed applications. The ACU may also be used to power the TXU or TCU only when a TXU and TCU are not co-located. In this case, the TXU would receive DC power from the TCU or the TCU would receive DC power from the TXU superimposed on the coaxial cable connected between the units. In standalone TXU or TCU operations, the optional ACU may be used to supply DC power directly to the applicable unit. In the case where a TXU and a TCU are co-located, it is recommended that both the TXU and TCU be powered directly from the ACU in lieu of supplying DC power from the TCU to the TXU or from the TXU to the TCU via the coaxial cable connected between the units. STRATA Remote Control Panels 2.3.4 For mobile or airborne operations, two Remote Control Panel models are currently available. Contact your Sales Representative for the latest information. STRATA TX Operators Guide/Tech Ref Manual Product Description 2-8 Both Remote Control Panel models provide simplified transmit operations by allowing the operator or pilot to select either analog or digital pre-configured Presets, Channels, and Offsets, depending upon the required operating mode. Standard Remote Control Panel The standard STRATA Remote Control Panel (See Figure 2-9) provides instrument panel remote control of the STRATA TX System for mobile operations and features 9 selectable Presets. For additional information, refer to the STRATA Remote Control Panel Operators Guide (part no. 400489). Figure 2-9: Standard Remote Control Panel For additional information, refer to the STRATA Aircraft Remote Control Panel Operators Guide (part no. 400490). Figure 2-10: Aircraft Remote Control Panel TXU and TCU Configurations 2.4 TXU Different configurations of the TXU are available, depending upon if your TX System contains a standalone TXU or if your TX System contains both a TXU and TCU. The different configurations are described below. If your TXU is equipped with either an analog (FMT) module or a digital (MPEG/COFDM) module and was ordered to operate in a standalone mode without a TCU, the front panel will contain an AUDIO connector. See Figure 2-11 on page 2-10. Aircraft Remote Control Panel The STRATA Aircraft Remote Control Panel (See Figure 2-10) is a simplified version of the standard STRATA Remote Control Panel. This panel provides instrument panel remote control of the STRATA TX System for airborne operations. This model features only two Presets for ease of operation. The unit is designed to fit a standard aircraft instrument panel and provides user-friendly controls, combined with well placed and easy to read LED displays and color indicators.

STRATA TX Operators Guide/Tech Ref Manual Routine Operation 3-9 Preparing for Operation 3.3 Each installation or deployment will have its own specific tasks according to the application and the installed hardware. 3.3.1 Mobile Installation For mobile applications such as aircraft or vehicle, the STRATA TX System is usually mounted in a bulkhead or compartment using an MRC Fixed Mounting Bracket. See Figure 3-5. Mounting brackets are available to mount from one to three units. Figure 3-5: Fixed Mounting Bracket Figure 3-6: Fixed Mounting Bracket on Tripod Fixed Mounting Bracket Quick Release MRC Tripod

(Typical) The cabling is permanently installed and power comes from aircraft (or vehicle) power. Portable Deployment 3.3.2 For situations where you need to mount a STRATA TX System and its Fixed Mounting Bracket to an MRC tripod, MRC also offers a Quick Release. See Figure 3-6. For situations where you are mounting to another type of tripod that doesnt directly accept the Quick Release, consult with MRC or your tripod manufacturer. MRC has Dovetail Adapter Plates that will convert some types of tripods to accept the Quick Release. Note The versatility of the Quick Release Mount and mating Dovetail Adapter Plate allows the Dovetail Adapter Plate to be attached to the bottom of the Universal Mounting Bracket and the Quick Release Mount to be attached to a non-MRC tripod, or vice versa. For optional methods of attaching your STRATA TX System to a non-MRC tripod, refer to the Installation Chapter on page 6-1 (part of the STRATA TX System Technical Reference Manual only) For portable applications where the STRATA TX System will be moved from place to place and set up each time, the system will STRATA TX Operators Guide/Tech Ref Manual Routine Operation 3-10 usually be mounted in an MRC Universal Mounting Bracket. The Universal Mounting Bracket will then be attached to a Quick Release for easy mounting on an MRC tripod. See Figure 3-7. Universal Mounting Brackets are required for each unit in the STRATA TX System, i.e., TXU, TCU, and an optional ACU. For applications using multiple units such as a TXU, TCU, and an ACU, a Mounting Plate is also used to provide additional stiffness. The Mounting Plate typically remains attached between the Universal Mounting Bracket and the Quick Release. The cabling between TX System units is also typically left in place. The power, antenna and audio/video connections are usually removed at the end of each deployment. For portable deployment situations where you are mounting to another type of tripod that doesnt directly accept the Quick Release, consult with MRC or your tripod manufacturer. MRC has Dovetail Adapter Plates that will convert some types of tripods to accept the Quick Release. Note The procedures and illustrations contained in the following paragraph are typical, reflecting use of an MRC tripod. Mounting to the Tripod Following are the general steps to mount a STRATA TX System to an MRC Tripod. These steps assume the TX System is already assembled into its Universal Mounting Bracket(s), and that the Mounting Plate and Quick Release are attached.

(Typical) Powering the STRATA TX System 3.3.3 The STRATA TX System will be in one of two configurations which provide different options for controlling application of DC power between units. Model variations are as follows:

STRATA TX Operators Guide/Tech Ref Manual Routine Operation 3-12 Superimposing DC Power In this configuration, DC power is superimposed with the IF signals between units and there is no manual control of DC power from the TCU. The DC power is superimposed on the coaxial cable between the TCU and the TXU. To turn DC power on and off, the operator uses the TCU and TXU front panel PWR switches and either the TCU or TXU control switch and alphanumeric display menus. The TXU DC ON COAX switch must be set to ON. Superimposing DC Power with Manual Control In this configuration, DC power superimposed on the IF signals between the units is manually controlled. The operator can manually turn DC power on or off to the TXU from the TCU or to the TCU from the TXU using DC ON COAX switches and TCU or TXU front panel control switches and alphanumeric display menus. The DC ON COAX switches provide the manual control and must be set to ON to allow application of DC power to the TXU , and TCU using the control switches and alphanumeric display menus. Powering STRATA TX Systems The method you use to power up your STRATA TX System will vary, depending upon the following:

The model of your STRATA TX System, whether or not you have DC power manual override control.

The transmitter configuration, whether you are using a single TCU, a single TXU, or a TCU and TXU

Whether the TCU and TXU are to be co-located or physically separated over some distance.

Following are some points to make this easier. Main Screen The Main Screen is your starting point for navigating through the Monitor and Control option screens. The Main screen provides the current values of the Preset selected and the selected Preset output power level. When the STRATA TX System completes its power-up sequence, it will display the Main Screen. A typical Main screen is shown in Figure 3-17. Figure 3-17: Typical STRATA TX Main Screen Currently Selected Preset Output Power Level Preset 3

. W Accessing the Main Screen You can access the Main screen at any time by scrolling to the end of the screens you are viewing

(either Monitor or Control). Your next click of the control switch will bring up the Main screen. Accessing the Monitor Screen You can access the Monitor option screens at any time by turning the control switch clockwise (cw). Accessing the Control Screen You can access the Control option screens at any time by turning the control switch counter-

clockwise (ccw). Default to Main Screen If you do not turn or push the control switch for a period of about 7 seconds, the display will default to the Main screen. If you turn the control switch within those 7 seconds, you will continue scrolling within that set of screens (Monitor or Control). Unit vs.System Control If youre using a standalone TXU or TCU, the menus and options that appear on the display will be based on the hardware option(s) installed in that individual unit. When you connect your TCU and TXU, the two units automatically detect what hardware is installed in each unit, and automatically configure the menus and options to match the installed hardware. The connected STRATA TX System then allows you to control the entire system from either the TXU or the TCU front panel. TXU and/or TCU Monitoring 3.5 Operations The STRATA TX System Presets are set to six possible modes of operation, based on the options contained in your TXU and/or TCU. These operating modes are established using the STRATA TX Configuration Utility software. The operating mode options available via the Configuration Utility software are as follows:

MPEG Only ASI Out (MPEG Output mode) (Standalone TCU Operation Only)

External 70MHz IF In (Ext IF Input mode)

MPEG/COFDM IF Out (COFDM - IF mode)

Press the control switch for one second to place the TX System in the transmit mode, as required. Controlling TCU to TXU DC Power on Coax 3.6.4 If your STRATA TX System requires the TXU and TCU to be mounted in separate locations, MRC recommends powering the TCU via the coaxial cable from the TXU. Note When the TCU and TXU are mounted in separate locations, it is recommended that DC input power be connected to the TXU. Since either unit may be powered from the other unit via DC power superimposed on the coaxial cable between the units, DC input power may therefore be applied to either the TXU or the TCU. If your TXU and TCU configurations contain DC ON COAX switches mounted on the units, these switches must be set to ON in addition to controlling DC power superimposed on the coaxial cable from the TXU to the TCU or from the TCU to the TXU. To apply DC power from the TXU to the TCU superimposed on the coaxial cable between the two units, perform the following steps. Notes This procedure must only be performed on STRATA TX Systems where the TXU and TCU are physically mounted in separate locations. This procedure may be performed using either the TXU or TCU control switch and display. Apply DC Power on Coax 1. 2. Verify the STRATA TX System is connected and powered up. See Powering the STRATA TX System on page 3-12. Observe the Main screen is displayed. See Figure 3-
