6. Read and Write Measurement Data
Calibration Data Arrays
The calibration data arrays contain Open/Short/Load/Low-loss capacitor measurement data
in the complex format. This data is used to calculate calibration coefficients. There are
eight arrays containing Open/Short/Load/Low-loss capacitor measurement data.
Use the following GPIB command to read the calibration data array.
• DATA:CAD{1-8}? on page 345
When the sweep type is set to segment sweep, the following GPIB command can be used
to read the calibration data array for each specified segment.
• DATA:SEGM{1-16}:CAD{1-8}? on page 350
Note that the above GPIB commands can be used to read a calibration data array measured
with the calibration data measurement points of “User-defined frequency points and
User-defined power points.”
Writing the calibration data array is not allowed.
