The MRC ODU ( See Figure 2-2 ) performs the signal up-
conversion from 70 MHz IF to RF (2 GHz or 7 GHz) and provides
signal amplification, as required. For dual band operation, two
separate ODUs are required, one for 2 GHz operation, and one
for 7 GHz operation.

2.3 System Components
The MTX5000 system consists of the IDU and the ODU(s). A
typical system is shown in
Figure 2-4 on page 2-4 . The IDU
contains the baseband circuitry, power supply, and control
modules. It accepts a wide variety of audio and video inputs,
both analog and digital, and generates a 70 MHz IF output. The
IDU also accepts IF inputs from external modulators.
The IDU can be controlled locally from the front panel controls or
it can be controlled remotely. The IDU can be controlled from a
PC at a remote location, such as a studio, via the PC web
browser. The optional Remote Access Subnotebook PC can
also be used to provide remote control of the IDU during mobile
operations.
