The EUT and simulators were placed on a 0.8m high wooden t
ground plane. The turn table rotated 360 degrees to determine the position of the maximum emissio
level. The EUT was set 3 meters away from the receiving antenna, which was mounted on an antenna 
mask. The antenna moved up and down between from 1meter to 4 meters to find out the maximum 
emission level. 
Broadband anten
antenna were set on measurement. In order to find the maximum emission, all of the interface cable
were manipulated according to EN55022 requirement during radiated test. 
The bandwidth setting on R&S Test Receiver ESBI 40 was 120kHz. 
The frequency range from 30MHz to 1000MHz was checked.
