10. Electrostatic Discharges (EN 61000-4-2)
10.1 Test criteria and test procedure
Operating environment;
Temperature:
20 ℃
Relative Humidity:
40 %
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 floor standing
equipment, EUT was placed on the reference plane on 10cm of insulating support
In case of table-top equipment, EUT was placed on a wooden table 0.8m above the reference planed On the
floor. A horizontal coupling plane(HCP) of 1.6*0.8m was placed on the table, and connected to the reference
plane via a cable with a 470 ㏀ resistor located in each end(0.5mm insulating support between EUT and HCP).
In both cases 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 in the same matter as the HCP.
The test was done by applying contact and air discharges to the EUT itself, and contact discharges to the
HCP and VCP. When applying the discharges to the HCP, the tip of the generator was located at each side of the
EUT, at 10cm distance. 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
HCP/VCP. Air discharges of ±8kV were applied to various points of the EUT at non-conductive surfaces.

11. Radio-frequency, Electromagnetic Field Keyed Carrier Immunity test (EN61000-4-3)
11.1 Test criteria and test procedure
Operating environment;
Temperature:
20 ℃
Relative Humidity:
40 %
The tests were performed at 3m distance in an anechoic chamber.
For floor-standing equipment, the EuT was mounted non-conducting support 0.1m above the
supporting plane. For tabletop equipment, the EuT was located on a wooden table 0.8m above the floor.
The EuT was exposed to the field from different angles, normally 0。, 90。,180。,270。,
and at both horizontal and vertical polarization(antenna height 1.75m)
A signal level of 3V/m, duty cycle 1/8 Pulse modulated with 217Hz sine wave was applied in the
frequency range 900MHz.
