ABSTRACT:
A calibration technique (200) uses a set of calibration standards to solve for unknown network parameters of calibration standards as well as error correction terms. A set of standards provides an over-determined system of calibration equations having more calibration equations than unknown error terms (202). The additional calibration equations are used to solve for the unknown network parameters of the calibration standards (210). Once solved, the network parameters of the calibration standards provide a more accurate determination of error terms for a network analyzer (214).
