FCC Coupling Decoupling Networks

Coupling Decoupling Networks (CDN)

The common mode current disturbance signal can be delivered to the EUT using a variety of coupling networks to inject the signal onto the unscreened cables, shielded cables, balanced cables, coaxial cables and power mains. Decoupling networks are used to insure that the disturbance signal does not influence the auxiliary equipment and are placed between the EUT and the auxiliary equipment.
