IEC/EN 61000-4-6 specifies the performance requirements for coupling/decoupling networks (CDNs) used in immunity testing, particularly in the 150 kHz to 230 MHz frequency range. The CDN S for multimedia is specifically engineered to support the testing of audio and video signals. Teseq's CDN S models allow for the safe injection of RF disturbances into shielded multimedia cables, ensuring that testing accurately reflects real-world EMI conditions. This capability helps manufacturers verify the robustness of their multimedia equipment, ensuring that devices remain functional and free from signal degradation during interference.
