8.3 Test set-up
See annex B
The EUT shall be exposed to at least 200 discharges , 100 each at negative and positive polarity ,at a
min of four test points (a min of 50 discharges at each point),One of the test points shall be subjected
to at least 50 indirect discharges(contact) to the centre of the front edge of the hori coupling plane,The
remaining three points shall each receive at least 50 direct contact discharges. If no direct contact test
points are available,then at least 200 indirect discharges shall be applied in the indirect mode.Test shall
be performed at a max repetition of one discharge per second.

be performed at a max repetition of one discharge per second.
On those parts of the EUT where it is not possible to perform contact discharge testing ,the equipment
should be investigated to identify user accessible points where breakdown may occur; A min of 10
single air discharges shall be applied to the selected test point for each such area.
should be investigated to identify user accessible points where breakdown may occur; A min of 10
single air discharges shall be applied to the selected test point for each such area.
Direct application of discharges to the EUT:
Contact discharge was applied only to conductive surfaces of the EUT.
Air discharges were applied only to non-conductive surfaces of the EUT.
During the test, it was performed with single discharges. For the single discharge time between
successive single discharges will be keep longer 1 second. It was at least ten single discharges with
positive and negative at the same selected point.
Indirect application of discharges to the EUT:
Vertical Coupling Plane (VCP):
The coupling plane, of dimensions 0.5m x 0.5m, is placed parallel to, and positioned at a distance 0.1m
from, the EUT, with the Discharge Electrode touching the coupling plane.
The four faces of the EUT will be performed with electrostatic discharge. It was at least ten single
discharges with positive and negative at the same selected point.
Horizontal Coupling Plane (HCP):
The coupling plane is placed under to the EUT. The generator shall be positioned vertically at a
distance of 0.1m from the EUT, with the Discharge Electrode touching the coupling plane.
The four faces of the EUT will be performed with electrostatic discharge. It was at least ten single
discharges with positive and negative at the same selected point.

9.3 Test set-up
See annex B
The testing was performed in a fully anechoic chamber. The EUT and load, which are placed on a table
that is 0.8 meter above ground, The transmit antenna was located at a distance of 3 meters from the
EUT. The frequency range is swept from 80 MHz to 1000MHz with the signal 80% amplitude
modulated with a 1 kHz sine wave. The rate of sweep did not exceed 1.5×10-3 decade/s. The step size
was 1% of fundamental. The dwell time at each frequency shall be not less than the time necessary for
the EUT to be able to respond. The field strength level was 3V/m. The test was performed with the
EUT exposed to both vertically and horizontally polarized fields on each of the four sides.
