4.2 Block diagram and test set up 
 
 
According to EN 55013 

 
 
 
The measurement was applied in an semi-anechoic 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 
EN55013/EN55022 requirement during radiated test. 
The bandwidth setting on R&S Test Receiver ESI26 was 120kHz. 
The frequency range from 30MHz to 1000MHz was checked.
