2 2.1 Product Description 2.2 Chapter Overview This chapter provides an overall description of the STRATA TX System, its components, and its capabilities. Here are the topics covered: System Description The STRATA TX System is a highly reliable, flexible, and compact portable microwave transmitter system ideal for tripod, airborne, or mobile installations. A typical STRATA TX System is composed of the Transmitter Unit (TXU) and the Transmitter Control Unit (TCU), as shown in Figure 2-1 on page 2-2.
Figure 2-1: STRATA TX System Block Diagram 1.84 MHz OOK Tone y y y y y NTSC PAL SDI ASI IF Telemetry Telemetry TCU IN TXU RF Out DC Power and/or IF RS-232 +28 VDC RS-232 The STRATA TX System TXU and the TCU may be operated in stand-alone configurations depending upon specific video applications. 2.2.1 System Options The STRATA TX System can be ordered configured for 1 of 11 specific RF bands as follows: • 3.4 to 3.9 GHz • 4.4 to 5.0 GHz • 6.4 to 7.1 GHz • 6.9 to 7.5 GHz • 7.4 to 8.
TCU The Transmitter Control Unit (TCU) can be equipped with either an FM Modulator or COFDM/MPEG module, or both. ACU The optional AC to DC Power Converter (ACU) provides +28 VDC power from an AC power source to power one or more units in a system. Remote Control Panels Optional Remote Control Panels are available to allow remote control of the STRATA TX System from an instrument panel during airborne or mobile operations. 2.2.
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.
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.
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 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.
