Abstract :
A weighted nonlinear least squares method to solve the 8- or 16-term calibration problem for a 2-port vector network analyzer is given. The method handles the connection repeatability problem, provides a test to verify whether the calibration problem can be solved with the available data and generates “soft” bounds on the accuracy of the calibration. The computational issues to obtain a fast and accurate implementation are stressed
