Metallic communication cable test methods - Part 4 - 9: Electromagnetic compatibility (EMC) - Coupling attenuation of screened balanced cables, triaxial method
IEC 62153-4-9:2018 is also available as IEC 62153-4-9:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62153-4-9:2018 applies to metallic communication cables. It specifies a test method for determining the coupling attenuation aC of screened balanced cables. Due to the concentric outer tube, measurements are independent of irregularities on the circumference and external electromagnetic fields. A wide dynamic and frequency range can be applied to test even super screened cables with normal instrumentation from low frequencies up to the limit of defined transversal waves in the outer circuit at approximately 4 GHz. However, when using a balun, the upper frequency is limited by the properties of the balun. Measurements can be performed with standard tube procedure (respectively with standard test head) according to IEC 62153-4-4 or with open tube (open test head) procedure.
The procedure described herein to measure the coupling attenuation aC is based on the procedure to measure the screening attenuation aS according to IEC 62153-4-4. This second edition cancels and replaces the first edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
– two test procedures, open head and standard head procedure;
– measuring with balun or with multiport respectively mixed mode VNA;
– extension of frequency range up to and above 2 GHz.
Méthodes d’essais des câbles métalliques de communication - Partie 4 - 9: Compatibilité électromagnétique (CEM) - Affaiblissement de couplage des câbles symétriques écrantés, méthode triaxiale
IEC 62153-4-9:2018 est disponible sous forme de IEC 62153-4-9:2018 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L'IEC 62153-4-9:2018 s'applique aux câbles métalliques de communication. Elle spécifie une méthode d'essai pour la détermination de l'affaiblissement de couplage, aC, de câbles symétriques écrantés. Grâce au tube concentrique extérieur, les mesures sont indépendantes des irrégularités de la circonférence et des champs électromagnétiques externes. Une large plage dynamique de fréquences peut être appliquée pour soumettre aux essais des câbles même fortement écrantés avec des instruments normaux depuis les basses fréquences jusqu’à la limite des ondes transversales définies dans le circuit externe à environ 4 GHz. Toutefois, lorsque des symétriseurs sont utilisés, la fréquence supérieure est limitée par les propriétés des symétriseurs. Des mesures peuvent être réalisées en suivant la procédure à tube normalisé (tête normalisée) selon l'IEC 62153-4-4 ou la procédure à tube ouvert (tête ouverte). La procédure de mesure de l'affaiblissement de couplage, aC, décrite ici est fondée sur la procédure de mesure de l'affaiblissement d'écran, aS, de IEC 62153-4-4. Cette deuxième édition annule et remplace la première édition, parue en 2008. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
– deux procédures d'essai: à tête ouverte et à tête normalisée;
– mesure avec un symétriseur ou avec un analyseur de réseau vectoriel en mode mixte ou multiport;
– extension de la plage de fréquences jusqu'à 2 GHz et au-delà.
