GSOLT: the calibration procedure for all multi-port vector network analyzers

The general method of 1- to n-port network analyzer calibration is described using the classical SOLT model which includes all linear errors of the network analyzer test-sets. This developed GSOLT-procedure works with vector network analyzers with n+1 measurement channels to measure n-port devices with high accuracy. The presented error correction algorithm of the GSOLT-procedure is outstanding regarding the simplicity and numerical robustness. The algorithm allows an easy programming for the correction of measurements of any device independent of the number of ports (1 to n). Experimental results attest to the very good precision of GSOLT error corrected measurements.
