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 coupling/decoupling networks EM TEST also supply special or customised coupling/decoupling networks.

The Lüthi AG, headquartered in Frenkendorf, Switzerland, is one of the world's leading and best known manufacturers of coupling/decoupling networks for conducted immunity testing and emission measurement as well as of EMC measuring clamps and accessories.

In January 2010 the Lüthi AG became a part of the EM TEST Group. It will be independently operated and the Lüthi brand will remain. As one of the pioneers in the development of EMC measurement clamps, Lüthi AG products are chosen by the most important suppliers of EMC measuring systems world-wide.
