IEEE 488.2 Common Commands

*OPC (Operation Complete)

Description The *OPC (operation complete) command will cause the instrument

to set the operation complete bit in the Standard Event Status Register

only when all pending operations are complete. The *OPC? query

places an ASCII “1” in the output queue when all pending device

operations are complete. There is a one second minimum delay

between the query and the response. A pending operation in the

Agilent 8922M or Agilent 8922S is any measurement which is armed

but not complete. When in remote operation with repetitive triggering

all measurements, apart from BER, are self-arming. When in remote

operation with single triggering all measurements, apart from BER,

are armed by sending the TRIGger[:IMMediate] command or

*TRG. The BER measurement is armed by sending the

TRIGger:BETest:RUN command.
