plane of 3m chamber. Measurements in both horizontal and vertical polarities were
performed. During the test, each emission was maximized by: having the EUT
continuously working, investigated all operating modes, rotated about all 3 axis (X, Y &
Z) and considered typical configuration to obtain worst position, manipulating
interconnecting cables, rotating the turntable, varying antenna height from 1m to 4m in
both horizontal and vertical polarizations. The emissions worst-case are shown in Test
Results of the following pages.

4.2. Description of Support Units
The EUT has been tested as an independent unit together with other necessary
accessories or support units. The following support units or accessories were used to
form a representative test configuration during the tests.

Note:
1. All the equipment/cables were placed in the worst-case configuration to maximize the emission during the test.
2. Grounding was established in accordance with the manufacturer’s requirements and conditions for the intended
use.

Limit (band edge) : least 50 dB below the level of the fundamental or to the
general radiated emission limits in Section 15.209,
whichever is the lesser attenuation.
1. The EUT was placed on the top of a rotating table 0.8
meters above the ground at a 3 meter chamber in
below 1GHz, 1.5m above the ground in above
1GHz. The table was rotated 360 degrees to
determine the position of the highest radiation.
2. The EUT was set 3 meters away from the
Test Procedure: interference-receiving antenna, which was mounted
on the top of a variable-height antenna tower.
3. The antenna height is varied from one meter to four
meters above the ground to determine the maximum
value of the field strength. Both horizontal and
vertical polarizations of the antenna are set to make
the measurement.
