B-12 Command Reference Model 2425 Service Manual
3. After sending a calibration command, repeatedly test the ESB (Event Summary)
bit (bit 5) in the status byte until it is set. (Use *STB? to request the status byte.)
4. Once operation complete has been detected, clear OPC status using one of two
methods: (1) use the *ESR? query, then read the response to clear the standard
event status register, or (2) send the *CLS command to clear the status registers.
Note that sending *CLS will also clear the error queue and operation complete
status.
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 2425. 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 com-
mand line, as covered above. Clear the SRQ by querying the ESR (using the *ESR?
query) to clear OPC status, then request the status byte with the *STB? query.
Refer to your controller's documentation for information on detecting and servicing SRQs.
