More information, Conducted emission test: RBW:9KHz,VBW:30KHz.ATN:10dB. Radiated emission test: RBW:100KHz,VBW:300KHz,ATN:20dB. The reply to question#2: Yes,A ferrite core is used on the power adaptor by the manufacturer of the adaptor. The ferrite core used on the video cable is to settle the problem of Out-going Reliability Test. It is not available to EMC. Is the non-EMC information to be included in the test report? I am not sure. thank you. Best Regards!

When the EUT is a tabletop system, a wooden table with a height of 0.8 meters is used and is placed on the ground plane as per EN 55022 (see Test Facility for the dimensions of the ground plane used). When the EUT is a floor-standing equipment, it is placed on the ground plane which has a 3-12 mm non-conductive covering to insulate the EUT from the ground plane. 2) Support equipment, if needed, was placed as per EN 55022. 3) All I/O cables were positioned to simulate typical actual usage as per EN 55022. 4) The EUT received DC power from an adaptor, and adaptor received AC power through a Line Impedance Stabilization Network (LISN) which supplied power source and was grounded to the ground plane. 5) All support equipment received power from a secon…
