This document specifies test methods for measuring the attenuation of converted differential-mode signals into common-mode signals, and vice versa, due to unbalance characteristics of cables used in analogue and digital communication systems. The unbalance attenuation is measured in, respectively converted to, standard operational conditions. If not otherwise specified, e.g. by product specifications, the standard operational conditions are a differential-mode which is matched with its nominal characteristic impedance (e.g. 100 Ω) and a common-mode which is loaded with 50 Ω.
