Variable Details
INPUT DEMOD MODE:
The DAP is capable of locking to a terrestrial (off-air) 8VSB or
CATV QAM Annex B modulated RF input signal. The selection
of the appropriate signal type must be made by the user to
ensure signals are properly identified during a scan. By setting
the Demod Mode the Channel Plan is automatically set to
Broadcast for 8VSB signals and Standard CATV for QAM
signals or 8VSB signals on the CATV channel plan.
