5.4 *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. (See *ESE 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 Lx\Ls Series. 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.
