Standard Class Assignments
Class assignment organizes calibration standards into a format compatible with the error
models used in the measurement calibration. A class or group of classes corresponds to the
systematic errors to be removed from the measured network 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.
