STATus:QUEStionable?
This query returns the value of the Questionable Event register. The Event register is a read-only register
which holds (latches) all events that are passed by the Questionable NTR and/or PTR filter. Reading the
Questionable Event register clears it.
NOTE: On the Agilent 6834B, each signal that is fed into the Questionable Status Condition
register is logically-ORed from three corresponding status signals that originate from each
phase.
