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.
