Measure Calibration Data
Perform Measurement
Use the following GPIB command to measure Open/Short/Load and, if necessary,
Low-loss capacitor calibration data used to calculate calibration coefficients.
SENS:CORR1:COLL on page 437
NOTE If a trigger source is set to an external trigger, execution of the above command does not
start calibration data measurement. After executing this command, prepare a trigger.
NOTE In the dielectric material measurement mode, an Open/Short/Load standard is used on the
DUT-connect surface of the text fixture to measure calibration data. If the dielectric
material measurement mode is selected, the test fixture is automatically set to Agilent
16543A, eliminating the need to select a test fixture in advance. In addition, fixture
compensation is disabled in this mode.
Completion of calibration data measurement can be detected by monitoring when the status
bit 0 of the Operation Status Event Register changes. Use one of the following GPIB
commands to monitor the status bit.

Enable Calibration
After measuring calibration data, use the following GPIB command to calculate calibration
coefficients. This GPIB command automatically enables calibration.
SENS:CORR1:COLL:SAVE on page 439
NOTE Calculation of calibration coefficients requires all of the Open/Short/Load measurement
data. If the above command is executed before data measurement is complete, an error
occurs and the command is ignored.
The following GPIB command can be used to disable the calibration function. However,
this command cannot be used to enable calibration.
SENS:CORR1 on page 419
NOTE When the calibration function is disabled, calibration data arrays and calibration coefficient
arrays are cleared.
