5.5 *OPC

This command causes the interface to set the OPC bit (bit 0) of the Standard Event Status

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.
