标准摘要
[中文适用范围]： 本部分IEC 62153涉及三轴管中管方法。这种三轴方法适用于确定匹配屏蔽连接器（包括电缆和连接器之间的连接）和电缆组件的表面转移阻抗和/或屏蔽衰减和耦合衰减。该方法还可以扩展到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。对于转移阻抗和屏蔽或耦合衰减的测量，只需要一个测试设置。 [外文原描述]： 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.
