In this webinar one- and two-port calibration of a Vector Network Analyzer (VNA) will be examined in depth. The properties of a typical SOLT calibration kit will be explained. The two-port, twelve term error model and the three-term error model for one-port calibration will be analyzed and the mathematics for three term, one-port calibration will be shown. Finally, Brian will highlight the simple steps to use more than three calibration standards for an over-determined calibration.
