Shieldingshop offers a variety of Com-Power designed Coupling/Decoupling Networks (CDN’s). These devices are built to be used for RF conducted immunity tests in accordance with IEC 61000-4-6.
This standard describes a consistent method for assessing the immunity of equipment or a system against a defined phenomenon. Since the last published edition in 2008, the use of CDN’s has been included in the standard.
IEC 61000-4-6 defines the different functions of a CDN as follows:
Coupling Network: electrical circuit for transferring energy from one circuit to another with a defined impedance.
Decoupling Network: electrical circuit for preventing test signals applied to the equipment under test (EUT) from affecting other devices, equipment, or systems that are not under test.
Because a CDN must be connected in series with the line(s) under test, Com-Power designed four different models. Each of these is designed for a specific type of power or I/O interface. For more detailed information, please refer to the table below or the specific product pages.
