Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for enabling self-calibration, without adding a calibration standard sample, e.g. a calibration kit with a network analyzer, in a vector network analyzer VNA. SOLUTION: Calibration is performed by acquiring an S parameter by using an unknown-though method, with an RF power source, two cables, a multi-stage impedance module and a test port connector.
