A coupling decoupling network, or CDN, is a piece of electronic test equipment used to couple the disturbing signal to several cables connected to the equipment under test. A coupling decoupling network is useful for immunity testing, or testing the reproducibility and protection of auxiliary equipment. CDNs can ensure that a disturbance signal does not influence auxiliary equipment. Typical application of CDNs usually spans from 9 to 150 kHz.
