12.4. Test Procedure

The EUT are placed on a table that is 0.8 meter height, and a Ground reference plane on the

table, EUT are placed upon table and use a 10cm insulation between the EUT and Ground

reference plane.

For Signal Ports and Telecommunication Ports

The disturbance signal is through a coupling and decoupling networks (CDN) or EM-clamp

device couples to the signal and Telecommunication lines of the EUT.

For Input DC and AC Power Ports

The EUT is connected to the power mains through a coupling and decoupling networks for

power supply lines. And directly couples the disturbances signal into EUT.

Used CDN-M2 for two wires or CDN-M3 for three wires.

All the scanning conditions are as follows:
