摘要
本篇文章主要介绍了中波广播发射环境,并对中波天馈线系统在干扰环境下的测量实践进行了介绍,首先通过矢量网络分析仪,利用其功能模块进行的准确测量干扰环境下中波天馈线参数测量方法。通过介绍中波发射台的主要功能,引出如果天馈线系统处在一个存在干扰的环境下其性能就会产生变化,从而指出为什么要做好干扰环境下中波天馈线参数测量。
This paper mainly introduces the medium wave broadcast transmitting environment, and introduces the measurement practice of the medium wave sky feeder system in the interference environment. Firstly,the vector network analyzer is used to measure the parameters of the medium wave sky feeder accurately in the interference environment. By introducing the main functions of the medium wave transmitting station, this paper points out that if the antenna feeder system is in an environment with interference, its performance will change, and then points out why it is necessary to measure the parameters of the medium wave antenna feeder well.
