Abstract
A radio frequency network analyzer connected to a multi-port test set is calibrated. An initial calibration is performed for each test set port in the multi-port test set. The initial calibration is performed by first performing a measurement calibration using calibration standards. The calibration standards are located in a reference plane located outside the multi-port test set. The measurement calibration yields initial calibration coefficients. Also the initial calibration includes measuring electronic standards within the multi-port test set to produce initial measured electronic standards. The initial calibration coefficients and the measured electronic standards are used to generate initial corrected electronic standards.
