Data-Based Model
The data-based model (85059B) of each calibration kit provides higher
accuracy for describing calibration standards than a polynomial model. The
data-based nominal S-Parameter model for each calibration standard is
generated by using a theoretical derivation or a high accuracy S-Parameter
measurement. These nominal S-parameter models are stored as part of the
data-based model. Errors that can be the result of polynomial model
approximations do not exist.
The data-based models may only be used with the SmartCal (Guided)
Calibration method of the Cal Wizard. Using the data-based models with the
Unguided Calibration method of the Cal Wizard is not allowed.
The data-based models may NOT be edited with the Advanced Modify Cal Kit
dialog box. Attempts to programmatically edit the definitions of the
data-based-model calibration standards will result in reported errors (i.e. SCPI
Execution Error).
In the PNA’s Modify Calibration Class Assignments dialog box
1
, the “Expanded
Math” feature is turned ON by default when the 85059B data-based model is
selected from a cal kit menu. In order to achieve a more accurate calibration,
Expanded Math uses the data at any given frequency from ALL measured
standards instead of using only the three standards specified in the class
definitions.
