摘要
从传输线基本理论出发,建立了两端口器件S参数的误差模型.以此误差模型为基础,利用OΩ、Os、50Ω三个校准件,对测量系统进行校准,通过求解校准方程,得出修正系数.即可获得精确的S参数.
From the basic theory of transmission line, an error model of parameter S for two end device has been set up. On the basis of this model, the measuring system was corrected using three calibrated com-ponents with load of 0Ω,0s and 50Ω respectively, then the solving calibration equations for correction coefficient were used to obtain precise parameter S.
