Abstract
Techniques are provided for performing full N-port calibrations in an environment in which a test set is used to connect an N-port DUT to an M-port VNA, where N>M. Techniques for incorporating port impedances as part of a calibration sequence are provided. Also provided are techniques for using sequential characterization and de-embedding to generate virtual calibrations that are then used in a renormalization process.
