Programming Commands
Common Commands
*OPC
The *OPC (operation complete) command sets the operation complete
bit in the event status register when all pending device operations
have finished.
Syntax
*OPC
*OPC?
Description The *OPC? query places an ASCII “1” in the output queue when all
pending device operations have finished.
This command is useful when the computer is sending commands to
other instruments. The computer can poll the event status register to
check when the Agilent 86120C has completed the operation. Use the
*OPC? query to ensure all operations have completed before continuing
the program. By following a command with an *OPC? query and an
ENTER statement, the program will pause until the response (ASCII
“1”) is returned by the instrument.
Be sure the computer’s timeout limit is at least two seconds, since
some of the Agilent 86120C commands take approximately one second
to complete.
