Com ma nd Reference
The CAL:COARSEDAC is used to initiate the calibration of the TE current setpoint by
allowing the user to enter calibration coefficients.
Two <nrf> values are required. The first one represents the TE current setpoint slope and
the second represents the offset.
This is a service related command. Calibration mode should not be entered unless the
user has the proper measurement equipment in place. See the Calibration section of
Chapter 5 for complete calibration instructions.
CAL:COARSEDAC 1,0 action: Enters a slope of 1 and offset of 0 for the TE current
setpoint calibration.
The CAL:COARSEDAC? query is used to report the current TE current setpoint
calibration coefficients.
The response data will be two values. The first represents represents the calibration
slope. The second represents the offset.
See the Calibration sectionCalibration section for complete calibration instructions
CAL:COARSEDAC? response: 1,0
The CAL:DEFault command sets all of the calibration constants to default (uncalibrated)
values.
None.
This command should only be used in the case that the calibration has become
corrupted or the instrument needs recalibration. Measurements and setpoints are not
guaranteed to meet accuracy specifications after this command is issued. Accuracy will
remain unspecified until calibration is performed on the instrument.
This is a service related command. Calibration mode should not be entered unless the
user has the proper measurement equipment in place. See the Calibration section for
complete calibration instructions.
CAUTION: The CAL:DEFault command resets all of the calibration constants to their
default values of 1 for slope and scale factor, and 0 for offset, thus invalidating the factory
calibration. Default calibration values are also listed in Chapter 5.
CAL:DEFault: The instrument sets all of its calibration constants to their default values.
