*OPC
This command causes the interface to set the OPC bit (bit 0) of the Standard Event Status register when it
has completed all pending operations. 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.
