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
-3
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.

5.5.2 TEST PROCEDURE
The EUT and its simulators shall be placed 0.1m high above the ground reference plane which is a min.
1m×1m metallic sheet with 0.65mm minimum thickness. This reference ground plane shall project
beyond the EUT by at least 0.1m on all sides and the minimum distance between EUT and all other
conductive structure, except the ground plane beneath the EUT, shall be more than 0.5m.
For input and AC power ports:
The EUT is connected to the power mains by using a coupling device which couples the EFT
interference signal to AC power lines. Both polarities of the test voltage should be applied during
compliance test and the duration of the test can’t less than 1min.
