5.5 *OPC
This command causes the interface to set the OPC bit (bit 0) of the Standard Event Status
register when the 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 such as measurement and calibration are
overlapped with subsequent commands sent to the AC/DC power source. The *OPC
command provides notification that all overlapped commands have been completed.
*OPC does not prevent processing of subsequent commands but Bit 0 will not be set until all
pending operations are completed. The *OPC 1 command must be part of the same
message with the command for which the OPC status is requested.
The query causes the interface to place an ASCII "1" in the Output Queue when all pending
operations are completed.
