Abstract The CDNE Coupling Decoupling Network is an essential tool for conducting electromagnetic compatibility (EMC) testing. By allowing precise injection and isolation of signals in compliance with international standards, the CDNE ensures reliable assessment of a device’s electromagnetic emissions. This paper focuses on the working principles, applications, and specifications of CDNE net...
What is Coupling and decoupling? Coupling is the energy exchange linkage between two circuits or two parts in one circuit, enabling energy to be transmitted from one circuit to another or from one part to another. Decoupling is the prevention of energy feedback from one circuit to another, to avoid unpredictable feedback reactions, resulting in abnormal operation of the next level amplifier or oth...
It is possible to do conducted immunity testing with the help of a coupling decoupling network (CDN). When connected to a generator, the CDNE-M316 will first cause a common mode disturbance into the EUT (EUT). An interference signal is sent to the EUT through the coupling network, which consists of cables and series conductors. Most electrical equipment will also interact with other devices, calle...
