扫频仪测传输线负载阻抗值的可行性研究

A study on the feasibility of using frequency sweep meter to measure load impedance of transmission line

在工程中常常会遇到对传输线的负载阻抗大小进行测量的问题，当负载为高频分布参数网络时，在没有专用仪器的情况下，测量成为一个难题。针对问题从理论上对用常规的扫频仪进行这种测量的可行性进行了分析，提出了测量方法和步骤。

In engineering practice it is frequent to measure the load impedance of a transmission line and it becomes a difficult problem when the load is a distributed network at high frequencies and it is lack of special instruments. The feasibility of using conventional frequency sweep meter for this measurement is analysed theretically,and the measurement methods and procedures are described in this paper.
