基于ZVA矢网的DBF接收机自动测试系统

介绍了基于ZVA矢网的DBF接收机自动测试系统的搭建。通过对变频器件DBF接收机测试原理以及R＆S ZVA矢网混频测试功能的说明,详细介绍了利用该矢网设计完成的一套DBF接收机自动测试系统,系统具有良好的通用性,测试精度和准确度高,测试速度快,能够同时完成7路DBF接收机的幅度、相位、隔离度等多个关键指标的自动测试。该系统的应用使得DBF接收机的测试效率大大提高,充分满足多路DBF接收机的测试要求。

Automatic test system for DBF receiver basing on ZVA Network Analyzer

This paper intends to introduce the construction of automatic testing system of DBF receiver on the basis of ZVA vec- tor network.It illustrates the design of DBF receiver automatic testing system with the vector network through instructing the testing principle of DBF receiver and the frequency-mixing testing function of RZ ZVA vector network.It turns out that this system is universal with high precision,accuracy and high speed operation,which can automatically test multiple key indexes of seven DBF receivers,such as range,phase and insulation.The application of this system enhances the testing efficiency of DBF re- ceiver greatly so that it can fully meet the testing request of multipath DBF receiver.
