The ODU shown in Figure 4, performs the signal up-conversion from 70 MHz IF to RF
[2 GHz or 7 GHz] and provides signal amplifi cation, as required.
The NewStream IDU is typically mounted in a standard 19-inch [48.3 cm] rack for
mobile installations and the ODU is mounted on an antenna mast. 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 from the
rear panel and 70 MHz IF for control of a legacy ODU. The IDU also accepts ASI from
external encoders.

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 Google Chrome Web browser. A PC, tablet or smartphone can also be used to
provide remote control of the IDU during mobile operations.
