摘要
结合电场辐射敏感度测试系统的基本工作原理和系统框图,提出了具体的方法来对测试系统进行维护和修理。为了在电场辐射敏感度测试系统出现故障时快速完成维修,把故障分为3大类加以分析,测不到场强,可沿着信号通路检查,根据检查情况判断故障位置;系统报错,可依据报错提示寻找到故障点;找不到仪器,可重点检查GPIB电缆和光纤。对反射功率大于前向功率故障的维修方法进行了详细讲解,并用维修实例对方法进行验证。
Based on the basic working principle and system block diagram of the electric field radiated susceptibility testing system,this paper puts forward specific methods to maintain and repair the test system.In order to quickly repair the fault in the electric field radiation susceptibility test system.Here are three major categories of fault analysis:The first type is the power is not measured.Judge the fault location according to the inspection situation.The second type is the system error,on the basis of error reporting to find fault point.The third type is can′t find the instrument,then focus on checking the GPIB cable and fiber.In this paper,the maintenance methods of the reflected power greater than the forward power failure are explained in detail.And verify the method with the maintenance example.
