多端口反射计的任意相位单位矢量五点校准法及误差分析

Calibration Method Using Five Unit Vectors with Arbitrary Phases for a Multi-Port Reflectometer and Its Error Analysis

本文讨论用五个任意相位的单位矢量来校准多端口反射计的方法。该方法使用简便 ,且适用于扫频测试。对于各类多端口反射计的校准、测量和误差分析 ,均是一种十分有效的方法。另外 ,本文利用该方法完成了对多端口反射计的误差分析 ,得到定量分析结果。

A method for the calibration of a multi-port reflectometer is presented, which utilizes five unit vectors with arbitrary phases to separate and obtain the near center point Γ N and the far center point Γ F. This method can be e asily used for the sweep-frequency measurement and is valid for the calibration ,measurement and error analysis of a multi-port reflectometer with amplitude re sponse.The quantitative error analysis using this method for a multi-port refle ctometer is given also.
