Cable Shielding Test Methods: A Comparison of Different Test Methods

This paper presents a comparison between different cable shielding test methods. Examples of cable shielding measurements using the wire injection and absorbing clamp method will compare both methods. The limitation of simple methods like the close field probe will be illustrated. For frequencies from 1-18 GHz the Reverberation Chamber is applied to characterize cable shields. It will be shown how the combination of the Wire Injection method with a Reverberation Chamber can provide a seamless cable shielding characterization from DC to 18 GHz. Finally a correlation between the Reverberation Chamber results with far field measurements in an Anechoic Chamber will illustrate the correlation of the presented measurement methods to radiated emission testing.
