Zusammenfassung
For the 7-term general TAN (Through-Attenuator-Network) self-calibration method of a four-sampler vector network analyser (VNA),
and for all derived calibration methods like TLN, TRL, TRM, TAR, or TMN, it is shown that a very simple evaluation procedure of the
seven error terms is possible, even if the Through connection is replaced by a reflectionless network with known transmission.
Expressions for the deviations of the measured S-parameters of two-port test objects (d.u.t.s) from the true values, which are caused
by deviations of the modeled S-parameters of nonideal calibration elements (“standards”) from their true values, are also presented.
Additionally, it is shown that a TAN calibration is also possible in case of unequal reflections of the Network.
