EM Test (Lüthi) CDN T-Type Coupling/Decoupling Network for Unshielded Lines

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. Dedicated CDNs are also used as per CISPR 15 and EN 55015 for measurement of emission.
A large range of appropriate coupling/decoupling networks as well as the necessary accessories for standard compliant levelling are avialable. 

You'll find an overview of all available CDN's on the datasheet. Apart from the listed standard T-type coupling/decoupling networks EM TEST also supply special or customised coupling/decoupling networks.
