Details
When *OPC is sent, the OPC bit (bit 0) in the Status Event Status Register is set after all pending
command operations have been executed. After all programmed operations are complete, the
instrument returns to idle, at which time all pending commands (including *OPC and *OPC?) are
executed. After the last pending command is executed, the OPC bit is set or an ASCII “1” is placed in
the Output Queue.
When the trigger model is executing, most sent commands are not executed. If a command cannot
be processed, an error event message is generated in the event log.
