Verifying the Input Reference Signal

The TSG-3800 automatically selects the input reference signal. Upon failure of the
input reference, the TSG-3800 selects the highest priority valid input providing that
Autoswitch is On. If Autoswitch is Off and the input reference fails, the TSG-3800
enters the Holdover mode.
The Input module providing the reference signal has its REF indicator illuminated; to
verify the reference in use, type:
REFERENCE
The TSG-3800 responds with:
TSG->REFERENCE
The Current Reference is «input»
TSG->
