UNIT DESCRIPTION
The input to the unit is a wideband AM and PM
modulated IF carrier in the VHF band. The IF
signal is power divided into four (4) channels
and up-converted to separate UHF bands. Any
combination of the four bands can be selected
and combined in one primary RF output. The
output level is controlled by a four bit digital
attenuator with 45dB range. The unit has a
second, selectable RF output to monitor the
primary RF output.
