Metallic cables and other passive components test methods - Part 4-15: Electromagnetic compatibility (EMC) - Test method for measuring transfer impedance and screening attenuation - or coupling attenuation with triaxial cell
IEC 62153-4-15:2021 specifies the procedures for measuring with triaxial cell the transfer impedance, screening attenuation or the coupling attenuation of connectors, cable assemblies and components, for example accessories for analogue and digital transmission systems, and equipment for communication networks and cabling. This second edition cancels and replaces the first edition published in 2015.This edition includes the following significant technical changes with respect to the previous edition:
a) measurement of coupling attenuation of balanced connectors, assemblies and components with balun and balunless added;
b) application of a test adapter was added;
c) application of a moveable shorting plane;
d) application of the triaxial "absorber" cell;
e) correction of test results in the case that the receiver input impedance R is higher than the characteristic impedance of the outer circuit Z2.
Méthodes d’essais des câbles métalliques et autres composants passifs - Partie 4-15 : Compatibilité électromagnétique (CEM) - Méthode d’essai pour le mesurage de l’impédance de transfert et de l’affaiblissement d’écran - ou de l’affaiblissement de couplage avec cellule triaxiale
L'IEC 62153-4-15:2021 spécifie les procédures de mesure de l’impédance de transfert, de l’affaiblissement d'écran ou de couplage des connecteurs, des cordons et des composants, par exemple les accessoires pour les systèmes de transmission numérique et analogique, et les équipements de réseaux de communication et de câblage, avec une cellule triaxiale. Cette deuxième édition annule et remplace la première édition parue en 2015. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) le mesurage de l’affaiblissement de couplage des connecteurs, cordons et composants symétriques avec ou sans symétriseur a été ajouté;
b) l’application d’un adaptateur d’essai a été ajoutée;
c) application d’un plan de court-circuit amovible;
d) application de la cellule "absorbeuse" triaxiale;
e) correction des résultats d'essai dans le cas où l’impédance d’entrée durécepteur R est supérieure à l’impédance caractéristique du circuit externe Z2.
