摘要

本文讨论了单端口矢量网络分析仪的射频校准方案，而不是传统的短开负载方案。在使用之前，校准标准是通过多项式拟合测量电压反射系数值来表征的。给出了各种校准方案的不确定度模拟曲线和测量不确定度实例。提出了一种针对特定器件在特定频率下自适应选择最佳校准方案的方法。

Generalised calibration schemes for precision RF vector network analyser measurements

This paper discusses RF calibration schemes for one-port vector network analysers other than the traditional short-open-load scheme. Before use, the calibration standards are characterised by fitting polynomials to measured voltage reflection coefficient values. Simulated uncertainty profiles and examples of measurement uncertainties obtained for various calibration schemes are presented. A method of adaptively choosing the best calibration scheme for a particular device at a particular frequency is suggested.
