*OPC
Sets the OPC (operation complete) bit in the standard event register. This occurs at the completion of the pending
operation. Refer to
Status Overview for more information.
Parameter Typical Return
(none) (none)
Set the Operation Complete bit: *OPC
– The purpose of this command is to synchronize your application with the instrument.
– Used in conjunction with initiated acquisitions, initiated transients, output state changes, and output to settling
time to provide a way to poll or interrupt the computer when these pending operations complete.
– Other commands may be executed before the operation complete bit is set.
– The difference between *OPC and *OPC? is that *OPC? returns "1" to the output buffer when the current
operation completes. No further commands can be sent after an *OPC? until it has responded. In this way an explicit
polling loop can be avoided. That is, the IO driver will wait for the response.
*OPC?
Returns a 1 to the output buffer when all pending operations complete.
Parameter Typical Return
(none) +1
Return a 1 when commands complete: *OPC?
– The purpose of this command is to synchronize your application with the instrument.
– Other commands cannot be executed until this command completes.
*OPT?
Returns a string identifying any installed options.
Parameter Typical Return
(none) AC68GPBU, AC68ALGU, or 0
Return installed options: *OPT?
– 0 (no options installed)
– AC68GPBU (GPIB installed), or AC68ALGU (analog interface board installed).
*PSC 0|1
*PSC?

– Questionable Data Register (STATus:QUEStionable:ENABle)
