5.3 ELECTROSTATIC DISCHARGE (ESD)
5.3.1 TEST SPECIFICATION
Basic Standard
EN 61000-4-2:2009
Discharge Impedance
330 ohm / 150 pF
Discharge Voltage
Air Discharge : 8 kV;
Contact Discharge: 4 kV
Polarity
Positive & Negative
Number of Discharge
Minimum 10 times at each test point
Discharge Mode
Single Discharge
1 second minimum
5.3.2 TEST PROCEDURE
The basic test procedure was in accordance with EN 61000-4-2:
a) The EUT was located 0.1 m minimum from all side of the HCP (dimensions 1.6m * 0.8m).
b) The support units were located another table 30 cm away from the EUT, but direct support
unit was/were located at same location as EUT on the HCP and keep at a distance of 10 cm
with EUT.
c) The time interval between two successive single discharges was at least 1 second.
d) Contact discharges were applied to the non-insulating coating, with the pointed tip of the
generator penetrating the coating and contacting the conducting substrate.
e) Air discharges were applied with the round discharge tip of the discharge electrode
approaching the EUT as fast as possible (without causing mechanical damage) to touch the
EUT. After each discharge, the ESD generator was removed from the EUT and re-triggered
for a new single discharge. The test was repeated until all discharges were complete.
f) At least ten single discharges (in the most sensitive polarity) were applied at the front edge of
each HCP opposite the center point of each unit of the EUT and 0.1 meters from the front of
the EUT. The long axis of the discharge electrode was in the plane of the HCP and
perpendicular to its front edge during the discharge.
g) At least ten single discharges (in the most sensitive polarity) were applied to the center of one
vertical edge of the Vertical Coupling Plane (VCP) in sufficiently different positions that the
four faces of the EUT were completely illuminated. The VCP (dimensions 0.5m * 0.5m) was
placed vertically to and 0.1 meters from the EUT.

5.4.2 TEST PROCEDURE
a) The testing was performed in a fully anechoic chamber. The transmit antenna was located at a
distance of 3 meters from the EUT.
b) The frequency range is swept from 80 MHz to 1000 MHz; 1.4 GHz ~2.7GHz, with the signal 80%
amplitude modulated with a 1 kHz sine-wave. The rate of sweep did not exceed 1.5 x 10

decade/s, where the frequency range is swept incrementally; the step size was 1% of preceding
frequency value.
frequency value.
c) The dwell time at each frequency shall be not less than the time necessary for the EUT to be able to
respond.
e) The test was performed with the EUT exposed to both vertically and horizontally polarized fields
on each of the four sides.
