Influence of calibration uncertainties on VNA S-parameter measurements

Abstract :
For the widespread 12-term TMSO calibration of 4-sampler vector network analyzers (VNAs), the sensitivity coefficients of the S-parameters of two-ports are derived with respect to the deviations of the reflection coefficients of the one-port calibration standards used. The obtained expressions are suitable for the establishment of the uncertainty budget.
