摘　　要：目前,矢量网络分析仪在微波领域中有着十分广泛的应用,由于端口功率输入超载或器件老化等原因,矢量网络分析仪会发生损坏,其中典型的故障便是源输出功率不足、接收机故障以及本振合成板故障等。基于此,以3种典型故障案例为切入点,阐述了功率测量法、自检结果分析法、观察对比法等在故障定位中的应用,为矢量网络分析仪的维修提供了参考。Currently,the network analyzers have the extremely widespread application in the microwave field.Due to port input power overload or instrument device aging,the network analyzers may be damaged,the typical faults are receiver fault,output power not enough and local synthesis fault.so taking these 3 typical faults as the starting point,the application of power measurement method,self-test result analysis method,observation and comparison method in fault location are described.It provides referrence for the service of network analyzers.
