Abstract

This paper discusses RF calibration schemes for coaxial one-port vector network analysers other than the traditional short-open-load approach. Before use, the calibration standards are characterised by fitting polynomials to measured voltage reflection coefficient values. Simulated uncertainty profiles and example measurement uncertainties are presented for various calibration schemes. Examples of non-SOL schemes and a method of adaptively choosing the best calibration scheme, based on minimising the uncertainty of measurement, for a particular frequency are also presented.
