Anotation

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. IEC 62153-4-5:2021 convient pour determiner l’affaiblissement d’ecran ou de couplage de cables metalliques de communication dans la plage de frequences de 30 MHz a 1 000 MHz (2 400 MHz), selon les performances de la pince. Il s’agit d’une variante de la methode triaxiale de l’IEC 62153-4-4 ou de l’IEC 62153-4-9. Etant donne que le circuit externe de cette methode de la pince absorbante n’est pas defini, les resultats d’essai obtenus dans differents lieux et laboratoires peuvent varier de plus de ±6 dB. Cette deuxieme edition annule et remplace la premiere edition parue en 2006. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a. reorganisation des articles et des annexes;
