5.3    Radiated radio-frequency electromagnetic field 

 

RESULT :                                                                                                              Pass 
 

The immunity against radio-frequency electromagnetic  fields was tested in accordance to 
EN55020:1994+A11:1996+A12,A13,A14:1999.  The test set-up was make according to 
EN61000-4-3: 1996+A1: 1998+A2:2001 in semi-anechoic chamber. The EUT has bees 
placed in center of a wooden turntable. The height of this table was 0.8m. The field strength 
was monitored by an isotropic sensor during the complete test. 
The isotropic sensor was located beside the equipment. The antenna has been orientated for 
both horizontal and vertical polarization. The distance between antenna the equipment under 
testing was at least 3m. The tests have been performed with the antenna facing each of the 
four side of the EUT.

5.4 Electrical fast transient / burst 

 
RESULT :                                                                                                              Pass 
 

 
The immunity against fast transients was tested in accordance to EN55020:1994 +A11:1996 
+ A12,A13,A14:1999. on all lines which length may exceed 3m according to the 
manufacturers specification.  Test set-up with capacitive clamp and fast transient noise 
generator was according to EN61000-4-4: 1995+A1:2001. 
The EUT has been placed on a wooden table 0.8m above the reference ground plane. 
The reference ground plane exceeded the projected geometry of the EUT and the capacitive 
clamp by more than 20cm. The clamp has placed directly on the reference ground plane.   
The un-used signal connector of the clamp has been terminated with a 50Ω resistor. 

The distance between the EUT and all other conductive structures. Except the ground plane 
beneath the EUT was more than 0.5m. The distance between clamp and EUT was about 30cm.
