Conducted Immunity - Measurement Standards : CEI 1000-4-4

To inject disturbances into the power inputs (in order to test the device facing the conducted disturbances), the following apparatus is used. This is closed to the CDN in part 3.4 (radiated susceptibility)


The coupling part (C_c=330nF) allows disturbances to go to the main high quality	The decoupling part (C_c=330nF) allows disturbances to be injected into the DUT

For the other access (data bus for instance), the disturbances are injected with the help of the coupling clamp. The DUT must be disposed on he same side as the disturbance injection.
