信息技术设备辐射骚扰诊断与对策研究

针对信息技术设备电磁辐射骚扰超标问题,通过分析辐射产生的典型模式,由外及内排查诊断,初步定位辐射骚扰源,再借助磁场探测器、电场探测器及频谱仪精确定位辐射骚扰源.根据骚扰源的特点,提出整改策略,并以液晶显示器辐射骚扰测试整改为实例加以说明.结果表明,通过分步诊断、分析、改进,可以有效减少电磁辐射骚扰强度.

Research and Diagnosis of Electromagnetic Radiated Interference Problems for Information Technology Equipment

In order to deal with the electromagnetic radiation problems for Information Technology equipment,the typical radiation patterns were analysised,diagnosis from outside to inside and positioning radiation interfereing source.Then find the precision interfereing source position with Magnetic detector,electric field detector and spectrum analyzer.Based on the characteristics of the interfereing source,strategys were proposed,and examples were illustrated.Results shows that radiated emissions can be suppressed ...
