GSO IEC 62153-4-2:2014 Scope

This part of IEC 62153 describes the injection clamp test method which determines the screening attenuation (as) of coaxial cables and the coupling attenuation (ac) of balanced shielded or unshielded data cables in a frequency range from 30 MHz up to 1 000 MHz and in a dynamic range up to 130 dB. NOTE 1 Contrary to the absorbing clamp method, the method described here uses an injection clamp according to IEC 61000-4-6. NOTE 2 Due to the low operational attenuation of the injection clamp, the coupling attenuation and the screening attenuation can be determined in a dynamic range up to 130 dB with common measuring equipment. Using an amplifier the dynamic range can be additionally improved.
