Remote Units Commands and Queries
W
CALibration:SELect {0|1} or {USER|FACTORY}, < cal_passcode >

command:
CAL:SELECT USER, 1234;
selects the USER calibration (if available) and requires that the
calibration passcode (“1234” in this example) be provided as a parameter.
If the calibration passcode is missing or incorrect, the Model 187 will beep

USER calibration if the user has previously performed a USER calibration
via the front panel interface or remotely.

as a parameter. The USER calibration is also made the current calibration
selection upon completion.
