5.2  Electrostatic discharge 

 

RESULT :

                                                                                                              Pass 

 
5.2.1 Measurement Procedure

 

The immunity against electrostatic discharge was tested in accordance with 
EN55020:1994+A11:1996 +A12,A13,A14:1999. A ground reference plane was located on 
the floor, and connected to earth via a low impedance connection. The return cable of the ESD 
generator was connected to the reference plane. In case of  a table top equipment, EUT was 
placed on the reference plane on 80cm of insulating support. And a vertical coupling plane 
(VCP) of 0.5*0.5m was located 10cm from the EUT’s sides. The VCP was connected to the 
reference plane via a cable with a 470㏀(2EA) resistor. The test was made by applying contact 

and air discharges to the EUT itself, and contact discharges to the VCP/HCP. When applying the 
discharges to the VCP the tip of the generator was located at the middle edge of the VCP. The 
VCP was located 10cm from each side of the EUT. Contact discharges of ±4kV were applied to 
various points of the EUT at conductive surfaces, and to the VCP. Air discharges of ±8kV were 

applied to various points of the EUT at non-conductive surfaces.

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.
