This command returns the decimal sum of the bits in the Data Questionable Modulation

enabled with no signal connected, a Modulation 1 Undermod condition exists (bit 0) and
a value of 1 is returned.

Key Entry N/A
Remarks Refer to “Data Questionable Modulation Status Group” on page 130
and “Data Questionable Modulation Event Register” on page 132 for
more information.
The equivalent PTR or NTR filters must be set before the condition
register can set the corresponding bit in the event register.
