operating and maintaining the equipment covered by this manual
to ensure awareness of potential hazards.
Notices Notices-iiPTX-PRO User and Technical Manual
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/cm² (milliwatts per square centimeters)
Conversions
dBi to numeric gain = Antilog (dBi/10)
Feet to centimeters = Feet * 30.48
Centimeters to Feet = cm * .0328
4 π = 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:
Notices Notices-iiiPTX-PRO User and Technical Manual
1. [P] RF power input. Convert watts to milliwatts =
Watts * 1000
2. [G] Antenna gain dBi. Convert to numeric gain =
Antilog (dBi/10)
3. [EIRP] Multiply P * G
4. [R] Convert centimeters to feet = Centimeters * .0328
5. Square R
6. Multiply R² * 4π
7. [S] Divide (R² * 4π) into EIRP
S = Power Density in milliwatts per square centimeters.
Note: At frequencies above 1500 MHz, S must not be
greater than 1

2.2.4 System Integration
System Operation Once the PTX-PRO is connected and
powered up, system settings can be selected or modified from
the front panel of the PTX-PRO.
System Configurations The PTX-PRO offers two levels of
system configurations designed to match the needs of different
personnel.
For the field operator, the PTX-PRO has up to nine 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 may be controlled from the front
panel include channel and offset.
For the advanced operator and technical staff, the Configurator
software allows complete control of parameters in the PTX-PRO.
The Configurator software runs on a Microsoft Windows-based
PC and connects to the PTX-PRO via an RS-232 serial interface
cable.

3.3 Preparing for Operation
Each installation or deployment will have its own specific tasks
according to the application and the installed hardware.
3.3.1 Portable Deployment - Typical
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.
3.3.2 Powering the PTX-PRO Transmitter
The procedures required to power up and power down the PTX-
PRO are contained in the following steps.
Power Up
1. Verify the power cable is properly connected to the
PTX-PRO front panel power connector.
2. 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.
If you are unsure of the power requirements or the
connections, refer to the “Installation” Chapter on
page 6-1.
3. Verify the power source is turned on.
4. Set the front panel PWR switch to on ( I ).
5. 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.

3.4 Using the Display Screens
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
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

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 Operations
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:
Routine Operation 3-7PTX-PRO User and Technical Manual
3.5.1 Using the Monitor Screens in COFDM Mode
When the PTX-PRO is operating in the COFDM mode, 70 MHz

Figure 3-5 on page 3-8 for the COFDM Monitor Menu Map.
3.5.2 Using the Monitor Screens in ASI/SDI Input
Mode
When the PTX-PRO is operating in the ASI In mode, the internal
MPEG encoder is bypassed and an externally supplied ASI
stream is routed to the MONITOR and RF output connectors.
See Figure 3-6 on page 3-9 for the ASI In Menu Map.
3.5.3 Using the Monitor Screens in Ext IF Input
Mode
When the PTX-PRO is operating in the Ext. IF In mode, the 70
MHz IF input signal to the SIGNAL INPUT connector is routed
through the transmitter. See Figure 3-7 on page 3-10 for the Ext.
IF Monitor Map.

Advanced Operation 5-2PTX-PRO User and Technical Manual
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.
5.2.5 Configurations
New configurations can created from scratch, updated from
existing files on your PC, or may be loaded in from a PTX-PRO
and modified. Once a configuration is created or modified and
saved, you can load the configuration into your PTX-PRO. The
steps required to load configuration changes are provided in the
applicable procedures.
Once a configuration is created or modified, it should be saved to
a file on your PC. The steps required to save configuration
settings are provided in the applicable procedures provided in
this Chapter.
Advanced Operation 5-3PTX-PRO User and Technical Manual
5.2.6 Channel Plans
New channel plans can be created from scratch, updated from
existing files on your PC, or may be loaded in from a PTX-PRO
and modified. Once a channel plan is created or modified and
saved, you can load the channel plan into your PTX-PRO. The
steps required to load channel plan changes are provided in the
applicable procedures provided in this Chapter.
Once a channel plan is created or modified, it should be saved to
a file on your PC. The steps required to save channel plan
settings are provided in the applicable procedures.
5.3 Create or Update a Configuration
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.
5.3.1 Using the Configurator Software
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.
5.3.2 Determine Licensed Options
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.

be walked upon. Protect cables against
pinching and chafing. Pay special attention
to locations where the cables enter or exit
an enclosure or make a sharp bend.
CAUTION Ensure that the electrical supply is protected
by over-current protection devices, as
required by the applicable electrical codes.
Each installation or deployment will have its own specific tasks
according to the application and the installed hardware. The
following section describes mounting and cabling the PTX-PRO.
6.5.1 Portable Deployment
For portable applications, the PTX-PRO will typically be moved
from place to place and set up each time. The power, antenna,
and audio/video connections are usually removed at the end of
each deployment.
Mounting - MRC Tripod The PTX-PRO will typically be
attached to a Quick Release Mount for easy mounting on an
MRC tripod. The Quick Release Mount is attached to the bottom
of the PTX-PRO using four 1/2-inch long, #6-32, flat head
screws. The Quick Release Mount typically remains attached to
the PTX-PRO. The Quick Release Mount and PTX-PRO are

Theory of Operation 8-2PTX-PRO User and Technical Manual
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.
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 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.
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.
