详谈单片机系统的EMC测试

所谓EMC就是:设备或系统在其电磁环境中能正常工作,且不对该环境中任何事物构成不能承受的电磁骚扰的能力。EMC测试包括两大方面内容:对其向外界发送的电磁骚扰强度进行测试,以便确认是否符合有关标准规定的限制值要求;对其在规定电磁骚扰强度的电磁环境条件下进行敏感度测试,以便确认是否符合有关标准规定的抗扰度要求。对于从事单片机应用系统设计的工程技术人员来说,掌握一定的EMC测试技术是十分必要的。EMC是电磁兼容(Electro- Magnetic Compatibility)的缩写,它包括电磁干扰(EMI)和电磁敏感性(EMS)两部分。由于电器产品在使用时对其它电器有电磁干扰,或受到其它电器的电磁干扰,它不仅关系到产品工作的可靠性和安全性,还可能影响其它电器的正常工作,甚至导致安全危险。
