Error Terms

Information in This Appendix

Information in This Appendix
Your PNA series network analyzer calculates error terms by measuring well-defined
calibration devices over the frequency range of interest and comparing the measured data
with an ideal model for the devices. The differences of the compared data represent
systematic (repeatable) errors of the analyzer system. The analyzer calculates and stores
these differences as error terms. These error terms are then removed from subsequent
measurements when error correction is on.
For details on the various levels and theory of error-correction, refer to the
NOTE
embedded help in the analyzer.

Summary of Content
How to use error terms as a preventive
maintenance and troubleshooting tool.
Procedure for measurement calibration.
Measurement calibration must be performed
before you can use error terms as a tool.
Flowgraphs of the error terms for 1 port and
2 port calibrations.
How to access error terms either manually or
programmatically using the analyzer front
panel or SCPI and COM/DCOM commands.
Values of the error terms of your analyzer.
Included are:
• a table of error term values
• typical response plots
• typical assembly failures
