B-8 Calibration Reference
Generating an SRQ on calibration complete
An IEEE-488 bus SRQ (service request) can be used to detect operation complete instead of
repeatedly polling the Model 2303. To use this method, send both *ESE 1 and *SRE 32 to the
instrument, then include the *OPC command at the end of each calibration command line, as
covered above. Clear the SRQ by querying the ESR (using the *ESR? query) to clear OPC sta-
tus, then request the status byte with the *STB? query to clear the SRQ.
Refer to your controller's documentation for information on detecting and servicing SRQs.
