摘要
在电子设备的电磁兼容(EMC)测试中,被测设备(EUT)的互连电缆电磁辐射较难抑制。本文通过交调干扰分析得出EUT内部的可能产生的频谱,并对这些频谱进行滤波处理,使其耦合到电缆线上的电磁辐射较小,同时对电缆上的电磁辐射进行屏蔽处理,保证EUT能通过EMC的辐射发射测试。
The radiate emission of EUT cable is difficult to restrain in EMC test .In this paper, the potential frequencies are educed cross-modulation, in order to decrease the transmission line radiation, filter and shield must be applied to the transmission line,which may guarantee EUT pass The radiate emission test in EMC.
