紧凑型城域波分仪传导抗扰度对策研究

Countermeasure Study on RF Conducted Immunity of Metro WDM Compact Instrument

紧凑型城域波分仪一般用于电信环境,外界干扰信号容易通过信号线或外壳耦合到紧凑型城域波分仪,影响其正常工作。基于以上情况,本文分析介绍GR-1089-CORE射频传导抗扰度的测试原理和设备在试验中出现的问题,然后从接口滤波器的选取及安装电路设计两方面出发,进一步提出一系列的对策措施,增强紧凑型城域波分仪的射频传导抗干扰能力。

Metro WDM compact instrument is generally used for base station environment.External interference signal affects its normal work through the signal line or shell.Based on the above situation,the paper analyses the test principle of RF conducted immunity in GR-1089-CORE.The problem is also discussed in the test.And a series of countermeasures are put forward to strengthen the conducted immunity capability of Metro WDM compact instrument from the filter selection and circuit design two-pronged approach.
