The EUT and its simulators are placed on a turn table which is 0.8 meter above ground. The turn table 
can rotate 360 degrees to determine the position of the maximum emission level. The EUT was 
positioned such that the distance from antenna to the EUT was 10 meters.The antenna can move up 
and down between 1 meter and 4 meters to find out the maximum emission level.   
Both horizontal and vertical polarization of the antenna are set on measurement. In order to find the 
maximum emission, all of the interface cables must be manipulated according to 

ETSI EN 301 

489-1:V1.6.1 (2005-09)

 on radiated measurement. 

The additional motch filter below 1GHz was used to measure the level of harmonics radiated emission 
during field dtrength of harmonics measurement. The bandwidth below 1GHz setting on the field 
strength meter (R&S Test Receiver ESCS 30 )is 120 kHz, and 1MHz bandwidth is adpted above 1GHz. 
The frequency range from 30MHz to 10

th

 harmonics is checked. 

According to ETSI EN 301 489-1:V1.6.1 (2005-09) 
           EN 55022:1998+A1: 2000+A2: 2003

The emission from the EUT was below the specified limits. The worst-case emissions are shown in 
section 12. The acceptance criterion was met and the EUT passed the test.
