标准范围

IEC 62153-4-5:20 21适用于确定30 MHz至1 000 MHz（2 400 MHz）频率范围内金属通信电缆的屏蔽或耦合衰减，具体取决于夹具的性能。它是IEC 62153-4-4或IEC 62153-4-9三轴方法的替代方法。由于这种吸收钳方法的外部电路未定义，在不同地点和实验室获得的测试结果可能会有至少±6 dB的差异。这第二版取消并取代了2006年出版的第一版。与上一版相比，此版本包括以下重大技术变更:a.条款和附件的重组；b.频率范围扩展到2.4 GHz；c.虚拟巴伦的应用分别是无巴伦测试程序与多端口VNA。

IEC 62153-4-5:2021 is suitable to determine the screening- or the coupling-attenuation of metallic communication cables in the frequency range of 30 MHz to 1 000 MHz (2 400 MHz), depending on the performance of the clamp. It is an alternative method to the triaxial method of IEC 62153-4-4 or IEC 62153-4-9. Due to the undefined outer circuit of this absorbing clamp method, the test results obtained at different places and laboratories could vary by at least ± 6 dB.
This second edition cancels and replaces the first edition published in 2006. This edition includes the following significant technical changes with respect to the previous edition:
a. reorganisation of clauses and annexes;
b. extension of frequency range to 2,4 GHz;
c. application of a virtual balun respectively balunless test procedure with multiport VNA.
