*OPC
This command causes the interface to set the OPC bit (Bit 0) of the Standard
Event Status register when the ac source has completed all pending operations.
(refer to “*ESE” on page 207 for the bit configuration of the Standard Event Status
registers.) Pending operations are complete when:
– All commands sent before *OPC have been executed. This includes overlapped
commands. Most commands are sequential and are completed before the next
command is executed. Overlapped commands are executed in parallel with
other commands. Commands that affect output voltage or state, relays, and
trigger actions are overlapped with subsequent commands sent to the ac
source. The *OPC command provides notification that all overlapped
commands have been completed.
– All triggered actions are completed and the trigger system returns to the Idle
state.
*OPC does not prevent processing of subsequent commands but Bit 0 will not be
set until all pending operations are completed. The query causes the interface to
place an ASCII “1” in the Output Queue when all pending operations are
completed.
