Notices Notices-iiPTX-PRO User and Technical ManualWARNING - RF Power HazardHigh levels of RF power are present in the unit. Exposure to RF or microwave power can cause burns and may be harmful to health.Remove power from the unit before disconnecting any RF cables and before inspecting damaged cables and/or antennas.Avoid standing in front of high gain antennas (such as a dish antenna) and never look into the open end of a waveguide or cable where RF power may be present.RF Exposure - Safe Working DistancesMRC provides this warning for safety purposes with the intent to inform the user of the potential hazard of 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 PTX-PRO 13 GHz Transmitter is a mobile transmitter system 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.Note Hazardous RF radiation limits and recommended distances may vary by country. Ensure that all applicable state and federal regulations are observed when using this transmitter.Calculations provided are for common antennas often utilized in the ENG environment. The following formula used is that suggested by OET 65.Calculating MPEEIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * PP = RF power delivered to the antenna in mWG = Power gain of the antenna in the direction of interest relative to an isotropic radiatorR = distance to the center of radiation of the antenna in centimetersS = MPE in mW/cm² (milliwatts per square centimeters)ConversionsdBi to numeric gain = Antilog (dBi/10)Feet to centimeters = Feet * 30.48Centimeters to Feet = cm * .03284 π = 12.57User InputRF power delivered to the antenna = WattsAntenna gain (referenced to isotropic antenna) = dBiDistance from the center of radiation = FeetCalculation steps:

Following are some points to make this easier.Main Screen The Main screen is your starting point for navigating through the Monitor and Control screens. The Main screen provides the current values of the Preset selected and the selected Preset output power level. When the PTX-PRO completes its power-up sequence, the Main screen will be displayed. A typical Main screen is shown in Figure 3-4.Figure 3-4: Main Screen - Typical 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 screen at any time by turning the control switch clockwise (cw). Preset 3 . WCurrently Selected PresetOutput Power LevelAccessing the Control Screen You can access the Control screen at any time by turning the control switch counter-clockwise (ccw). Default to Main Screen If you do not turn or press the control switch within a period of approximately 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).3.5 PTX-PRO Monitoring OperationsThe PTX-PRO Presets are set to five possible modes of operation. These operating modes are established using the Configurator software. Operating mode options displayed on the Monitor screens are indicated below in bold fonts. Operating mode options available via the Configurator software are as follows:• MPEG/COFDM IF Out (COFDM mode)• COFDM Only - ASI In (ASI/SDI In mode)• External 70MHz IF In (Ext IF Input mode)• LMS-T (Terrestrial) (LMS-T mode) Once the PTX-PRO is set up and powered up, you will be able to check its configuration and monitor its operation. When configuration settings are established for the individual Presets using the Configurator software, the individual Preset operating modes should be recorded for quick reference.The following sections describe how to use the Monitor screens. Here are the tasks described:

The procedures allow use of the Configurator in the on-line mode with the Configurator software connected to the PTX-PRO via an RS-232 interface.5.3.2 Determine Licensed OptionsPrior to preparing or modifying any PTX-PRO configuration settings in the offline mode, you must determine what licensed options are contained in your PTX-PRO.If you have not previously recorded your PTX-PRO licensed options, you must perform this procedure. In order to determine the licensed options contained in your PTX-PRO, you must connect your PTX-PRO to the Configurator software via an RS-232 link to your PC. When your PTX-PRO is powered up and is connected to the Configurator in the on-line mode, the Configurator software automatically detects the licensed options contained in your PTX-PRO.After determining what licensed options are contained in your PTX-PRO, you must record the options. You can then disconnect from the Configurator software and can prepare configuration settings in the offline mode without having your PTX-PRO connected to your PC and the Configurator software.The flowchart required to determine the licensed options contained in your PTX-PRO is contained in Figure 5-1 on page 5-4.

8 Theory of Operation 8-1PTX-PRO User and Technical ManualTheory of Operation8.1 Chapter OverviewThis chapter provides technical details about the design and functioning of the PTX-PRO 13 GHz Transmitter (PTX-PRO). This chapter is intended to complement information contained in the “Product Description” Chapter on page 2-1. The descriptions in this chapter assume you are already familiar with the information contained in Chapter 2. We recommend that you review Chapter 2 before beginning to read this one.Here are the topics covered:8.2 System Architecture The PTX-PRO is designed around a flexible, modular architecture. The overall PTX-PRO system architecture for a PTX-PRO is shown in Figure 8-1.The PTX-PRO is a versatile portable transmitter designed to accept an IF 70 MHz input signal or composite video signal, audio signals, or SD/HD SDI signals or ASI/SDI signals from external sources and to provide a 13 GHz microwave signal output.Topic PageSystem Architecture 8-1System Theory of Operation 8-2Command and Control Power Supply 8-2MPEG/COFDM Encoder/Modulator Module 8-2Figure 8-1: PTX-PRO System ArchitectureAll configurations are available with either NTSC or PAL system modulation. PTX-PRO key features are:• RF output high/low power selection for 13 GHz operation • System modulation scheme:Digital: COFDM or LMS-T• COFDM Modulation: Selectable 6, 7, or 8 MHz bandwidthQPSK, 16 QAM, or 64 QAM• COFDM Modulation with selectable Guard Interval technology (1/4, 1/8, 1/16/ or 1/32)• Forward Error Correction (FEC) (1/2, 3/5, 5/6, or 7/8)• MPEG encoding with SD and optional HD video solution technologies• Front panel local control• Wide choice of antennas.PTX-PRO TX SystemRS-232120/240 VAC, 50/60 Hz or +11.0 to +36.0 VDCAUDIO/AES/EBURF OUTMONITORSDI/SD/HDSD I/ASI IN PU TSIGNAL IN PU T
Theory of Operation 8-2PTX-PRO User and Technical ManualAll PTX-PRO configurations are available with Standard Definition (SD) or SD and optional High Definition (HD) video technologies.The PTX-PRO can accept a wide variety of signal formats and includes an RF up-converter for use in transporting signals over a microwave link. The PTX-PRO also contains an MPEG/COFDM module. The PTX-PRO contains a universal power supply and can operate on 90 to 264 VAC, 50/60 Hz or +11.0 to +36.0 VDC. 8.3 System Theory of Operation The PTX-PRO is comprised of the following primary components:• Command and control universal power supply module• MPEG encoder/COFDM modulator moduleSee Figure 8-2 on page 8-3 for a block diagram of the 13 GHz PTX-PRO. The PTX-PRO also contains the IF/RF module which accepts either a 70 MHz COFDM or external 70 MHz input signal and up-converts these signals to the 13 GHz RF band. The PTX-PRO can therefore serve as a standalone digital video microwave transmission system.The RF frequency synthesizer circuit included in the IF/RF module, along with the command and control module, provide the means to channelize RF video and audio signals in the 13 GHz RF band. Standard U.S. FCC band plans, as well as custom channel plans, may be accommodated using the MRC Radio Configurator (Configurator), when the Configurator software is connected to the PTX-PRO.8.3.1 Command and Control Power Supply The PTX-PRO command and control power supply modules contain external and internal communications circuitry, as well as supplying necessary system voltages. The PTX-PRO power supply accepts a wide range of DC input voltages (+11.0 to +36.0 VDC) or 90 to 264 VAC, 50/60 Hz. The supply converts the input voltage to the DC voltages required by the rest of the PTX-PRO circuits and distributes the appropriate output voltages to the various circuits.The on-board microprocessor manages the system configuration and operation of all modules to which it is connected, e.g., MPEG/COFDM, IF/RF modules, etc. This ensures that the PTX-PRO can permit switching modes of operation, change system Presets, etc. Therefore, system control may be accomplished using front panel control or remote control.8.3.2 MPEG/COFDM Encoder/Modulator Module The MPEG/COFDM module is the heart of the PTX-PRO digital mode circuitry. This circuit may be configured to accept a wide range of digital or analog video and audio signal inputs and provide COFDM IF (70 MHz) video signal outputs.The various signal inputs and outputs are connected through the PTX-PRO combiner circuit where they are switched under software control.
