Standard Class Assi gnments
Standard Class Assign ments
Class assignment organizes calibration standards into a forma t compatible with the er ror
models used in the measurement calibrati on. A clas s or group of cl asses corresponds to the
systematic errors to be removed from the measured netw ork analyzer response. Table A-1
through A-3 list the classes of the devices in the kit for various network analyzers. This
information resides on the calibration definitions disk included in the kit.
