6. Electrostatic Discharges
6.1 Test Procedure
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 plane.
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 the front edge
of each HCP opposite the center point 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 up to ±4Kv were applied to various points of the EUT at
conductive surfaces, and to the HCP/VCP. Air discharges up to ±8Kv were applied to various points of
the EUT at non-conductive surfaces.
Ungrounded equipment, or ungrounded part(s) of equipment, cannot discharge itself similarly to class I
mains-supplied equipment. If the charge is not removed before the next ESD pulse is applied, it is
possible that the EUT or part(s) of the EUT be stressed up to twice the intended test voltage. Therefore,
double-insulated equipment could be charged at an unrealistically high charge, by accumulating several
ESD discharges on the capacitance of the class II insulation, and then discharge at the breakdown voltage
of the insulation with a much higher energy. In the case of class II & III equipment.
To avoid of unrealistical high charge, it is possible to ionize “using ionizer” before each discharge.

7. Radio-frequency, Electromagnetic Field Keyed Carrier Immunity test
7.1 Test Procedure
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 a 217Hz sine wave was applied in the
frequency range 900MHz. During the test the 1kHz unwanted noise level comes from the speaker was
detected using microphone and selected level meter
