ABSTRACT:
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.
