Phase Selectable
This command returns the value of the Questionable Event register for a specific output of a three-phase
ac source. The particular output phase must first be selected by INST:NSEL.
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.
