Material
Selection
When performing calibration in the dielectric material measurement mode, use the
following GPIB command to select whether the Load standard included with the Agilent
16453A or a user-defined Load standard is used.
• SENS:CORR1:CKIT on page 420
User-Defined Load Standard Value
If the Load standard included with the Agilent 16453A is used, each parameter of the Load
standard is set to the E4991A predefined value. When a user-defined Load standard is used
to perform calibration, the following GPIB commands must be used to define the
parameters for the Load standard.
Select Calibration Data Measurement Points
Select calibration data measurement points from the following table. Note that when fixed
points are used to measure calibration data, calibration coefficients are calculated through
interpolation.
Use the following GPIB command to select calibration data measurement points.

NOTE Calibration data measurement points are set in coordination with fixture compensation data
measurement points. To select fixture compensation data measurement points, use the
SENS:CORR2:COLL:FPO command.
