The CN Type T coupling network is used to inject RF disturbances into telecommunication lines of the EUT, simulating real-world conditions where communication lines of up to 2 pairs encounter electromagnetic interference. Operating across the 0 Hz to 150 kHz frequency range, CN Type T includes an integrated decoupling network that isolates the test voltage from auxiliary equipment, eliminating the need for an external decoupling transformer. As specified by IEC/EN 61000-4-16, CN Type T provides a complete solution for testing telecommunication devices, ensuring they maintain performance and data integrity when subjected to conducted disturbances.
