Abstract: Embodiments describe methods of correcting S-parameter measurements for a DUT. The method includes coupling at least one tracking module associated with a set of electrical standards to a S-parameter measurement device to form a test system. An initial calibration for the test system is then determined. This may include measuring the S-parameters of the electrical standards, generating a calibration along a calibration plane, generating a calibration along a correction plane and determining at least one error adapter from the calibrations. The DUT is coupled to the test system and the S-parameters of the DUT are measured. Changes in the initial calibration are tracked using the tracking modules. Tracking may include measuring the S-parameters of the electrical standards, generating a correction plane calibration and generating a corrected calibration plane calibration from the correction plane calibration and the error adapter(s). The measured S-parameters are corrected using the tracked changes.
