determines the coupling or screening attenuation of metallic communication cables in the frequency range of 30 MHz to 1 000 MHz. It is an alternative method to the injection clamp method of IEC 62153-4-3 or the triaxial method of IEC/ PAS 62338. 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 ¿6dB.
