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.
