A.7
*OPC — OPERATION COMPLETE COMMAND
*OPC
Syntax:
*OPC
Description: Causes power supply to set status bit 0 (Operation Complete) when pending operations are
complete. This command sets Standard Event Status Register bit 0 (see Table A-2) to “1” when all
previous commands have been executed and changes in output level have been completed. This
command does not prevent processing of subsequent commands, but bit 0 will not be set until all
pending operations are completed. (1 = set = enable function, 0 = reset = disable function). (See
example, Figure A-1.) As an example, the controller sends command(s), then sends *OPC. If control-
ler then sends *ESR?, the power supply responds with either a “0” (if the power supply is busy execut-
ing the programmed commands), or a “1” (if the previously programmed commands are complete).
(See example, Figure A-1.)
A.8
*OPC? — OPERATION COMPLETE QUERY
*OPC?
Syntax:
*OPC?
Return value: <1> (ASCII) placed in output queue when power supply has completed operation.
Description: Indicates when pending operations have been completed.When all pending operations are com-
plete (all previous commands have been executed and changes in output level have been completed)
a “1” is placed in the Output Queue. Subsequent commands are inhibited until the pending operations
are completed. *OPC? is intended to be used at the end of a command line so that the application pro-
gram can monitor the bus for data until it receives the “1” from the power supply Output Queue. (See
example, Figure A-1.)
