如何利用现场校准减少大型医用电气设备现场EMC测试的误差

摘要

In this paper, we ifrst study the method and necessity of in-situ calibration for EMC radiated emission testing instrument in non-standard test environment, and speciifcaly developed a special method of calibrating the ifeld EMC testing instrument, based on in-situ calibration result the engineer can eliminate the radio interferences,which exist in the surrounding environment over the large medical electrical equipment,and with this help the testing engineer wil be easier to reduce the error form ifled EMC test.%本文先探讨了电磁兼容辐射发射测试设备在非标准试验环境中如何进行现场校准和其必要性，再具体研究了对现场测试用仪器的特殊校准方法，以便在需要开展大型医疗电气设备现场辐射发射测试的相关人员尽可能的剔除环境背景中的无线电干扰，大幅度减少现场检测结果误差。
