Quantifying Variance Components for Repeated Scattering-Parameter Measurements

Abstract
We quantify random uncertainties for scattering-parameters repeatedly measured with a vector network analyzer (VNA), focusing on variations due to multiple calibrations, disconnects, and repeat measurements. We describe a two-stage nested design, which allows us to model the random effects, and present results for a series of coaxial measurements performed by making use of an open-short- load-thru (OSLT) calibration kit with Type-N connectors.
