In collaboration of Working Group 8.42 (
Data analysis and measurement uncertainty) and Working Group 2.22 (High-Frequency Measuring Techniques) a novel math-based procedure for the high-accuracy calibration of vector network analyzers (VNAs) has been evaluated. The procedure is based on a single VNA measurement employing a high precision airline. From this measurement, the error characteristics of the VNA are determined over the entire frequency range using a sophisticated estimation procedure. Virtual experiments were used to optimally tune the parameters of the estimation procedure.
The novel calibration procedure has been confirmed by a comparison with an established but involved reference method. The novel calibration procedure now enables high-accurate calibrations of VNAs at low costs, as well as easy performance checks of mechanical calibration kits and electronic calibration units.
