Optimization of automatic exclusion algorithm of the vector network analyzer measuring equipment

[摘要] Automatic elimination of measuring equipment (deambedding) in measuring S-parameters has become widespread with the development of modern vector network analyzers. This handy feature allows to get the measurement results in the "ready form", eliminating the need to perform calculations manually with the transformation of S-parameters matrices many times (by the number of points in the source ∗.s2p file). At the same time, this function has certain limitations that become critical with the exclusion of measuring equipment with large (more than 30 dB) losses. This paper describes the experience of determining the limitations of the applicability of the deambedding operation, provides an analysis of the reasons for their existence, and also suggests a method for eliminating these limitations.
