标准摘要
[中文适用范围]： 本标准（IEC 62153-4-7）涉及同轴管中管法。该同轴方法适用于确定互连屏蔽连接器的表面转移阻抗和/或屏蔽衰减和耦合衰减（包括电缆与连接器之间的连接）以及电缆组件。该方法也可扩展用于确定平衡或多针连接器和多芯电缆组件的转移阻抗、耦合衰减或屏蔽衰减。对于转移阻抗、屏蔽或耦合衰减的测量，仅需一套测试装置。 [外文原描述]： IEC 62153-4-7:2021 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 62153-4-7:2021 deals with the triaxial tube in tube method. This triaxial method is suitable to determine the surface transfer impedance and/or screening attenuation and coupling attenuation of mated screened connectors (including the connection between cable and connector) and cable assemblies. This method could also be extended to determine the transfer impedance, coupling or screening attenuation of balanced or multipin connectors and multicore cable assemblies. This third edition cancels and replaces the second edition published in 2015 and its Amendment 1:2018.This edition includes the following significant technical changes with respect to the previous edition: - Annex E contains informative information about the direct measurement of screening effectiveness of connectors; - Annex F gives normative information about mixed mode parameters; - Annex G contains normative information about accessories for measuring coupling attenuation; - Annex H discusses the low frequency screening attenuation.
