摘　　要：本文开展了基于Maury公司的Tuner和Agilent公司PNA-X矢量网络分析仪组建的超快噪声参数测量系统的不确定度评定研究工作,通过分析测量系统的输入、输出数据,独立开发了不确定度评定的测量模型,设计了满足国际标准ISO/IEC98-3要求的不确定度评定方法,编制了不确定度仿真软件,首次报道了四个噪声参数的不确定度数据,最佳估计值和95%概率下得包含区间。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.
