STAT:OPER:ENAB? <n>

Programming Examples - 4

A negative transition filter that functions as described under STAT:OPER:NTRPTR commands in Chapter 3. It is a read/write register.

A register that latches any condition that is passed through the PTR or NTR filters. It is a read-only register that is cleared when read.

A register that functions as a mask for enabling specific bits from the Event register. It is a read/write register.

The outputs of the Operation Status register group are logically-ORed into the OPER(ation) summary bit

(7) of the Status Byte register.
