金属电缆和其他无源元件试验方法第4-15部分:电磁兼容性（EMC）测量传输阻抗和屏蔽衰减或三轴单元耦合衰减的试验方法

[中文适用范围]： 本部分 IEC 62153 规定了使用三轴单元测量连接器、电缆组件和部件（例如模拟和数字传输系统的附件，以及通信网络和电缆设备）的传输阻抗、屏蔽衰减或耦合衰减的程序。测量可以通过将测试设备直接应用于三轴单元或使用 IEC 62153-4-7 中的管中管方法来实现。 [外文原描述]： IEC 62153-4-15:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62153-4-15:2021 specifies the procedures for measuring with triaxial cell the transfer impedance, screening attenuation or the coupling attenuation of connectors, cable assemblies and components, for example accessories for analogue and digital transmission systems, and equipment for communication networks and cabling. This second edition cancels and replaces the first edition published in 2015.This edition includes the following significant technical changes with respect to the previous edition: a) measurement of coupling attenuation of balanced connectors, assemblies and components with balun and balunless added; b) application of a test adapter was added; c) application of a moveable shorting plane; d) application of the triaxial "absorber" cell; e) correction of test results in the case that the receiver input impedance R is higher than the characteristic impedance of the outer circuit Z2.
