Abstract

IEC 62153-4-9:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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:
โ€“ two test procedures, open head and standard head procedure;
โ€“ measuring with balun or with multiport respectively mixed mode VNA;
โ€“ extension of frequency range up to and above 2 GHz.
