标准摘要
[中文适用范围]： 该三轴方法适用于确定配对屏蔽连接器（包括电缆和连接器之间的连接）和电缆组件的表面传输阻抗和/或屏蔽衰减和耦合衰减。该方法还可扩展以确定平衡或多针连接器和多芯电缆组件的传输阻抗、耦合或屏蔽衰减。对于传输阻抗和屏蔽或耦合衰减的测量，只需要一种测试装置。 [外文原描述]： IEC 62153-4-7:2015 describes a triaxial method, 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. For the measurement of transfer impedance and screening- or coupling attenuation, only one test set-up is needed. This edition includes the following significant technical changes with respect to the previous edition: The document is revised and updated. The changes of the revised IEC 62153-4-3:2013, and IEC 62153-4-4:2015, are included. Measurements can be achieved now with mismatch at the generator site, impedance matching devices are not necessary. The contents of the corrigendum of April 2016 have been included in this copy.
