RF Coupling Networks/ LISN

Coupling decoupling networks (CDN), CN, CDND, CDNE and line impedance stabilization networks (LISN) are an essential component in EMC RF testing. Teseq offers a wide range of CDNs and LISNs used in different applications according to various international standards.

  • CDN

    IEC/EN 61000-4-6 specifies the design and performance of a range of coupling/decoupling networks (CDNs). AMETEK CTS offers an extensive range of CDNs (M, AF, S, CAN series) which fully comply with the requirements of the standard.

  • CDNE

    CISPR 15 edition 9 offers different methods for the measurement of radio disturbance characteristics of electrical lighting equipment. One of these is the CDNE method which specifies the use of a coupling_/_decoupling network for emission measurement (CDNE) to measure disturbance voltages in the 30 to 300 MHz frequency range.
