EM Test (Lüthi) CDN S4 4-Line Coupling/Decoupling Network (BNC, USB, Sub-D9)

The EM Test (Lüthi) CDN S4 4-Line Coupling/Decoupling Network (BNC, USB, Sub-D9) is a configurable CDN used for shielded signal lines. Please specify configuration under CDN Power Capacity in the order box above.

Immunity test to conducted disturbances, induced by radio-frequency fields according to the standards IEC/EN 61000-4-6 and IEC/EN 60945 introduce different types of coupling/decoupling networks according to the characteristics of the interconnection lines. 

For testing conducted RF immunity according to IEC 61000-4-6 and IEC / EN 60945 different types of CDN are required, depending on cable. Specific CDNs are also used for emission measurements according to CISPR 15 and EN 55015. 

EM Test (Lüthi) offers a wide selection of appropriate coupling / decoupling networks, and current probes and the associated accessories for standard-compliant calibration.
