标准摘要
[中文适用范围]： IEC 62153-4-7:2021+AMD1:2025 CSV 规定了同轴管中管方法。该三轴方法适用于确定连接的屏蔽连接器（包括电缆与连接器之间的连接）和电缆组件的表面转移阻抗和/或屏蔽衰减和耦合衰减。此方法还可以扩展至用于确定平衡或多针连接器和多芯电缆组件的转移阻抗、耦合或屏蔽衰减。本第三版取消并替代了2015年发布的第二版及其2018年的修正案1。与前一版相比，本版包含了以下重大技术变更：- 附录E提供了关于直接测量连接器屏蔽效果的信息；- 附录F提供了关于混合模式参数的规范信息；- 附录G提供了关于测量耦合衰减附件的规范信息；- 附录H讨论了低频屏蔽衰减。 [外文原描述]： IEC 62153-4-7:2021+AMD1:2025 CSV 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.
