Test Results on the New TSZ Calibration Method

The new ANA calibration method TSZ has been developed and success fully tested by computer simulation . TSZ is a modified version of the well known TSD method and is intended for those practical measurement situations where the insertion of the reference transmission 1ine, of nominal wave-impedance and of finite length, as " Delay " standard, is either physically difficult Of totally impossible. TSZ uses, besides a "Through" (T) and a "Short" (S), two "Impedance Standards" (Z), to be connected in series or in parallel to the measurement 1ine. The results of computer - simulated calibration tests show the rigorous validity of the new method, which equals that of the older TSD.
