A Study on Network Analyzer Self-Calibration Using an Arbitrary Device

This paper studies the feasibility of calibrating a vector network analyzer with an arbitrary device serving as a calibration standard. The short-open-load-reciprocal and thru-attenuator-network (TAN) procedures are, respectively, extended to develop short-open-load-device and thru-attenuator-device algorithms. The developed algorithms eliminate the limitations and broaden the applicable range of the thru-open-load-reciprocal and TAN procedures by using the device under test as a transfer standard. To benchmark the developed algorithms against the thru-reflect-line algorithm, experiments are conducted with a nonreciprocal device having theoretically symmetrical reflections. Results of the experiments verify the applicability of the developed algorithms.
