Embodiments of the present invention are directed towards systems, methods, and computer readable media for performing multiport vector network analysis. Embodiments of the present invention relate to a multiport network analysis that is derived from a family of two port calibration techniques including Thru/Reflect/Line (TRL), Thru/Reflect/Match (TRM), Line/Reflect/Line (LRL), Line/Reflect/Match (LRM) and several others. An improved calibration method enables the use of a simplified switch matrix to perform accurate vector network analysis in communications and networking systems. After determining some characteristics through conventional methods, a two tier load match correction is performed on the results. The improved correction mechanism enables the system to perform comparably to systems with more complicated switch matrices.

Calibration techniques for simplified high-frequency multiport differential measurements

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&#x3e;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.
