Schwarzbeck CDN and CDNE Coupling Decoupling Networks Product Catalog Listing

Introduction to Schwarzbeck CDN and CDNE coupled decoupling networks:

CDN Introduction:

The Chinese name of CDN is Coupling / Decoupling Networks and the English name is Coupling / Decoupling Networks, which are used to inject common mode interference into the equipment under test (EUT). In addition, CDNs provide sufficient decoupling between the auxiliary equipment (AE) and the interfering signals, and the requirements for CDNs and their applications are described in the IEC 61000-4-6 standard (Immunity to conducted interference due to radiofrequency electromagnetic fields). The CDN test method can be used on a wide range of cable types and connectors.

CDNE Introduction:

The Chinese name of CDNE is Coupling / Decoupling Networks for emission, from the English name Coupling / Decoupling Networks for emission than the CDN more than an emission: emission, so CDNE is independent of the CDN another test instrument.

CDNE is mainly derived from another type of CDN proposed by the CISPR15-2018 standard.The CDNE test method is used only for luminaire emission measurements and complies with EN 55015 of 2009.

Difference between CDN and CDNE:

CDN can use an external amplifier and signal source to inject common-mode interference into the EUT from the CDN input port; whereas CDNE can only test the RF interference component on the EUT power or signal lines, so CDNE cannot be used for power injection.
