Abstract
A method of compensating a calibration for a vector network analyzer includes performing calibrations on at least a pair of ports to determine error terms associated with each port wherein at least one of the error terms is based upon selecting the reactance of the load standard from a set of potential values in a manner such that the reference reactance errors are reduced.
