Evaluation of Measurement Uncertainty on Noise Parameters of Low Noise Package Device

A study on the evaluation of measurement uncertainty of a super fast noise parameters measurement system, which consists mainly of an automatic impedance tuner produced by Maury Micro-wave Corporation and Agilent PNA-X VNA equipped with an internal low noise figure measurement re-ceiver, is introduced. This paper gives a thorough analysis of system＇s input and output data, based on which a new measurement model is developed independently by us, and a new method of evaluating measurement uncertainty is designed according to the international standard of ISO/IEC98-3 . A simula-tion software developed by the authors of this paper is used to obtain the measurement uncertainty data of four noise parameters, giving the best estimated data and probability distribution. It is we reported for the first time.
