This article presents a new method of accuracy verification of calibrated vector network analyzers based on the modified calibration comparison technique. The method is of particular interest for low frequency ranges as well as for cost-effective S-parameter measurement systems where the use of conventional ripple test and precision reference air line standards may be impractical and/or relatively...
A method is introduced for determination of a vector network analyzer's calibration residual errors for measurement of the reflection coefficient. The method utilizes unscented Kalman filtering and spline interpolation time domain techniques. All three residual errors are calculated by processing the measured reflection coefficient of a single verification device, such as an air line terminated with...
