Discovery variables are QAMB Only, QAMA Only (N/A for USA), VSB (8VSB for Broadcast/
OTA) and All Mod..
All Mod. includes all prior digital modulation schemes.
All schemes include Analog. Using All Mod. will make the discovery time take longer as the
meter searches through more modulation possibilities to find a match.
The typical setting when using the meter on a CATV feed is USACAB and QAMB.
NOTE: This setting also populates the Master TV Plan parameter on page 8.
