Determination of efficient parameters of calibrated one-port vector network analyzers for limited frequency ranges using a short-circuited air line

This article presents a new method of accuracy verification of calibrated one-port vector network analyzers based on the least mean square algorithm. The method is of particular interest for significantly limited frequency ranges as well as for costeffective S-parameter measurement systems where the use of conventional ripple test may be impractical and/or relatively expensive. Experimental studies were conducted for few frequency ranges in coaxial measurement environment.
