PTX-PRO User and Technical Manual Notices Notices-i WARNING - RF Power Hazard High 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 Distances MRC 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 MPE 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:

Graphs and data will vary, based on the actual transmitter, output power, frequency, and antenna utilized. The plot provides the permissible output of the transmitter 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.

PTX-PRO User and Technical Manual Routine Operation 3-4 DC Fuse The rear panel DC fuse provides DC input power protection for units used with DC power sources. RS 232 DB-9 Connector The RS 232 DB-9 connector provides connections for factory test or to a Microsoft Windows-based PC when using the Configurator software. The connector also provides connections for Wayside data. Preparing for Operation 3.3 Each installation or deployment will have its own specific tasks according to the application and the installed hardware. Portable Deployment - Typical 3.3.1 For portable applications where the PTX-PRO will be moved from place to place and set up each time, the system will typically be mounted on an MRC Quick Release Mount for easy attachment to an MRC tripod. Other mounts are also available. For additional information, refer to the Installation Chapter on page 6-1. Powering the PTX-PRO Transmitter 3.3.2 The procedures required to power up and power down the PTX-

PRO are contained in the following steps. Power Up 1. 2. Verify the power cable is properly connected to the PTX-PRO front panel power connector. Verify all front and rear panel cables and connectors have been properly connected. If you are unsure of the connections, refer to the Installation Chapter on page 6-1. Connect the power cable to the power source. 3. 4. 5. If you are unsure of the power requirements or the connections, refer to the Installation Chapter on page 6-1. Verify the power source is turned on. Set the front panel PWR switch to on ( I ). The normal power-up sequence is as follows:

- The PWR LED above the PWR switch should illuminate and should quickly change colors from red, to green, to amber, to green, and should remain green.

- The alphanumeric display should light up and quickly display a self-test screen, then the version of the firmware, and finally the Main screen.

- Some typical screens are shown in Figure 3-3. Exact screens displayed will vary.

- The PTX-PRO will typically power up using the last

settings in use when power was turned off. If the PTX-PRO does not power up normally, refer to the Troubleshooting Chapter on page 4-1. Figure 3-3: Typical PTX-PRO Power Up Screen Firmware Version PTX-PRO V X.X.X Main Screen Preset #1 0.00W C 3 PTX-PRO User and Technical Manual Routine Operation 3-5 Power Down 1. 2. Set the PWR switch to off ( 0 ). Set the power source power to off. Using the Display Screens 3.4 As you use the PTX-PRO, you will interact extensively with the screens displayed on the alphanumeric display. 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 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 screen at any time by turning the control switch clockwise (cw). Accessing 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). PTX-PRO Monitoring Operations 3.5 The 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:

PTX-PRO User and Technical Manual Routine Operation 3-6 utilizes a single carrier modulator and supplies a configurable LMV-S signal to the transmitter RF output and MONITOR connectors. This mode is operational for QPSK and 16 QAM modulation formats. See Figure 3-8 on page 3-11 for the LMS-T Monitor Menu Map.

Introduction Chapter on page 1-1 Product Description Chapter on page 2-1 Routine Operation Chapter on page 3-1 Configurator Software 5.2.2 This chapter also assumes the Configurator software is installed and operating on your PC and that you are familiar with its tabs, buttons, pages, etc. Settings 5.2.3 Before beginning to create or program a configuration or channel plan into your PTX-PRO, you must define what settings are required. PTX-PRO User and Technical Manual Advanced Operation 5-1 5.2.4 System Rules CAUTION Do not make any configuration changes to your PTX-PRO while the PTX-PRO is connected to a radio system that is actively transmitting. Attempts to program configuration changes into a PTX-PRO when the radio system is actively transmitting will interrupt broadcast operations. When configuring your PTX-PRO on-line (connected to a PC), the following system rules must be followed.

When the PTX-PRO is properly connected to your PC and the system is powered up, the Configurator software will automatically detect your PTX-PRO, your hardware configuration, and the licensed options contained in your PTX-PRO.

The PTX-PRO must be powered up prior to initializing the Configurator software.

The configuration settings can be saved to the PTX-PRO or can be saved to a file and can be recalled at a later date.

Configuration settings may be loaded into the Configurator from your PTX-PRO, may be modified, and may be loaded into your PTX-PRO and/or saved to a file in the on-line mode.

The PTX-PRO must not be placed in the transmit mode when utilizing the Configurator software.

Channel plans may be created in the on-line mode or in the offline mode. Channel plans created in the offline mode can be saved to a file on your PC and can be recalled at a later date.

Channel plans may be loaded into the Configurator from your PTX-PRO, may be modified, and may be loaded into your PTX-PRO and/or saved to a file in the on-line mode.

PTX-PRO configurations and channel plans may be created or modified from a file on your PC in the on-line mode.

When selecting options in the on-line mode, if the option is a licensed option that is not contained in your radio, the option may not be displayed, e.g., if you do not have the LMS-T licensed option in your radio, the LMS-T tab will not be present on the Configurator. In certain instances, licensed options may be displayed on a Configurator page, but if your radio does not contain the licensed option, the option will be inactive, you cannot select the option, and you cannot load the option into your radio.

The procedures required to create or update configurations and/

or channel plans are provided in the following sections. Configurations 5.2.5 New configurations can created from scratch, updated from existing files on your PC, or may be loaded in from a PTX-PRO and modified.

Create or Update a Configuration 5.3 There are various ways to create or modify a configuration on-

line with the PTX-PRO connected to a PC via an RS-232 link.

Create a configuration on-line.

Load in an existing configuration from a file and modify it on-line. Load in a configuration from the PTX-PRO and modify it. Load and modify individual configuration pages.

Once a configuration is created and saved to a file on your PC, the configuration file can be loaded into the PTX-

PRO. Each of these methods is explained in detailed steps in the following sections. Using the Configurator Software 5.3.1 The MRC Radio Configurator software has an easy-to-use Graphical User Interface (GUI) to access Preset configuration settings and channel plan settings. The Configurator software is accessed through the MRC Radio Configurator icon displayed on your PC desktop. The settings are grouped into pages according to function. The pages are accessed using tabs. Pages also contain option buttons, pull-down menus, text boxes, radio buttons, and check boxes to select or activate different functions and options. Procedures contained in this Chapter utilize easy-to-use flowcharts to navigate through the various procedures. 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. Determine Licensed Options 5.3.2 Prior 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.

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:

Topic System Architecture System Theory of Operation Command and Control Power Supply MPEG/COFDM Encoder/Modulator Module Page 8-1 8-2 8-2 8-2 System Architecture 8.2 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.

Digital: COFDM or LMS-T

COFDM Modulation:

Selectable 6, 7, or 8 MHz bandwidth QPSK, 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 User and Technical Manual Theory of Operation 8-1 All 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. System Theory of Operation 8.3 The PTX-PRO is comprised of the following primary components:

Command and control universal power supply module

MPEG encoder/COFDM modulator module See 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. Command and Control Power Supply 8.3.1 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.
