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 8 signal/data lines. According to IEC/EN 61000-4-5 resp. 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. EM TEST also offers special coupling/decoupling networks for railway test applications.

The EM TEST CNV 508 series of coupling decoupling networks are multifunctional CNVs for the application of Surge and Ringwave pulses onto signal/data lines. The standard CNV 508 models combine three different applications; coupling of Surge pulse via capacitor or gas arrestor and coupling of Ringwave pulses via capacitor being required by the relevant standards. The required coupling mode can easily be selected by means of a simple jumper. The CNVs also include the required decoupling part consisting of decoupling inductors of 20mH for each line. To protect the auxiliary equipment being needed for testing the DUT an additional protection circuit is integrated at the signal/data line input. EM TEST offers CNV 508 coupling/decoupling networks for various test voltages up to 10kV and for higher signal voltages/currents (up to 600V and up to 4A). Dedicated CNVs are available e.g. for railway applications as per EN 50155 and for other customer specific test applications.
