Details

The Coupling- / Decoupling Networks are used to inject common mode disturbances to Equipment under Test (EuT). Further the CDNs provide sufficient decoupling between Auxiliary Equipment (AE) and disturbance signal. The requirements for CDN and their application are described in the standard IEC 61000-4-6 (Immunity to conducted disturbances, induced by radio-frequency fields). CDNs have a common mode impedance of 150 Ohm and are available for a multitude of cable types and connectors.
