Remote Operation

*OPC (Operation Complete)

*OPC (Operation Complete)

Syntax

*OPC

*OPC?

Description

The *OPC and *OPC? commands are used to synchronize remote interface software to internal module events.

•The *OPC (operation complete) command will cause the instrument to set the operation complete bit in the Standard Event Status Register when any switching operations that were in process at the time the *OPC command was received have completed.

•

•

*OPC is also used to signal the end of MEM:SAVE operation.

*OPC? causes a 1 to be put into the output buffer when any switching operations that were in process at the time the *OPC? command was received have completed.

If no switching operations were in process at the time the command was sent, the response will be generated immediately. Hence *OPC or *OPC? should only be sent after an operation has been initiated.

Example Command

OUTPUT 709;“*OPC”

Example Query The following sequence is correct, because the OPC command is sent after the operation is initiated:

OUTPUT 709; “ROUT:CLOS (@1(1,3,5,7,9));*OPC?”

ENTER 709;A

PRINT A

The following sequence is incorrect, because the OPC command is sent before the operation is initiated:

*OPC?;ROUT:CLOSE (@1(1,3,5,7,9));
