标准摘要
[中文适用范围]： IEC 62153 的这一部分给出了现场测试方法，用于确定模拟和数字通信系统中使用的已安装链路和通道的耦合衰减。该方法用于确定布线系统中干扰功率对信号功率的衰减，反之亦然。这决定了布线对系统 EMC 性能的影响。注 1：已安装链路和通道的耦合衰减取决于布线组件的性能（平衡和屏蔽，如果适用）@工艺（尤其是屏蔽的端接）以及接地。此过程决定了这些参数的总体效果。注 2：该方法不能用于验证整个系统@（包括有源组件）是否符合辐射和抗扰度 EMC 标准。 [外文原描述]： IEC 62153-4-14:2012(E) is applicable to the in-field test method that is used to determine the coupling attenuation for installed links and channels used in analogue and digital communication systems. This method is used to determine the attenuation of disturbing power to signal power in a cabling system, and vice versa. This determines the influence from cabling on the EMC performance of a system. This standard is part of the IEC 62153 series titled Metallic communication cable test methods.
