Abstract :
Coupling and decoupling networks (CDNs) for two-wire, four-wire, and eight-wire telecommunication ports have been developed for use in radio-frequency conductive immunity testing. The requirements for the CDNs are based on the IEC recommendations, the telecommunication conditions, and the induced voltage at the telecommunication ports. The circuit parameters are chosen to meet these requirements. The measured characteristics of the CDNs show that they satisfy the requirements, and that they can be used for the immunity testing
