EM TEST CNV 504N / CNV 508N8-series Coupling/Decoupling Networks

CNV 504N/508N-series Coupling/decoupling networks for signal/data lines.

Surge pulses or Ringwave pulses are applied to unshielded unsymmetrical interconnection lines (signal/data lines) by means of standalone coupling/decoupling networks. For such testing EM TEST offers a range of CNVs for either 4 or 8 signal/data lines.

According to IEC/EN 61000-4-5 and IEC/EN 61000-4-12 the pulses are coupled via different coupling elements such as capacitors or gas arrestors depending on the characteristics of the line signals.
