8.3 Test set-up and test procedure 

 
 
 
The measurement was applied in an semi-anchonic chamber.  
The EUT and simulators were placed on a 0.8m high wooden turntable above the horizontal metal 
ground plane. The turn table rotated 360 degrees to determine the position of the maximum emission 
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 antenna was used as receiving antenna. Both horizontal and vertical polarization of the 
antenna were set on measurement. In order to find the maximum emission, all of the interface cables 
were manipulated according to EN55022 requirement during radiated test. 
The bandwidth setting on R&S Test Receiver ESVS10 was 120kHz. 
The frequency range from 30MHz to 1000MHz was checked. 
The mode (playing) was checked on radiated disturbance test and all the test results are listed in the 
sec.7.6.
