1.5 Description of Test Mode
To investigate the maximum EMI emission characteristics generates from EUT, the test
system was pre-scanning tested base on the consideration of following EUT operation mode
or test configuration mode which possible have effect on EMI emission level. Each of these
EUT operation mode(s) or test configuration mode(s) mentioned follow was evaluated
respectively.

Note:
(1) For all test, we have verified the construction and function in typical operation. And all the
test modes were carried out with the EUT in transmitting operation in maximum power with
all kinds of data rate.
According to ANSI C63.10 standards, the measurements are performed at the highest,
middle, lowest available channels, and the worst case data rate as follows:
BLE Mode: GFSK Modulation Transmitting mode.
(2) During the testing procedure, the continuously transmitting with the maximum power
mode was programmed by the customer.
(3) The EUT is considered a portable unit; in normal use it was positioned on X-plane. The
worst case was found positioned on X-plane. Therefore only the test data of this X-plane
was used for radiated emission measurement test.

1.6 Description of Test Software Setting
During testing channel& Power controlling software provided by the customer was used to
control the operating channel as well as the output power level. The RF output power
selection is for the setting of RF output power expected by the customer and is going to be
fixed on the firmware of the final end product power parameters of RF setting.

4.3 Test Procedure
The EUT was placed 0.8 meters from the horizontal ground plane with EUT being
connected to the power mains through a line impedance stabilization network (LISN). All
other support equipments powered from additional LISN(s). The LISN provide 50 Ohm/
50uH of coupling impedance for the measuring instrument.
Interconnecting cables that hang closer than 40 cm to the ground plane shall be folded back
and forth in the center forming a bundle 30 to 40 cm long.

the cable may be terminated, if required, using the correct terminating impedance. The
overall length shall not exceed 1 m.
LISN at least 80 cm from nearest part of EUT chassis.
The bandwidth of EMI test receiver is set at 9 kHz, and the test frequency band is from
0.15MHz to 30MHz.

5.3 Test Procedure
(1) The measuring distance of 3m shall be used for measurements at frequency up to 1GHz and
above 1 GHz. The EUT was placed on a rotating 0.8m high above ground, the table was
rotated 360 degrees to determine the position of the highest radiation.
(2) Measurements at frequency above 1GHz. The EUT was placed on a rotating 1.5m high
above the ground. RF absorbers covered the ground plane with a minimum area of 3.0m by
3.0m between the EUT and measurement receiver antenna. The RF absorber shall not
exceed 30cm in high above the conducting floor. The table was rotated 360 degrees to
determine the position of the highest radiation.
(3) The Test antenna shall vary between 1m and 4m, Both Horizontal and Vertical antenna are
set to make measurement.
(4) The initial step in collecting conducted emission data is a spectrum analyzer peak detector
mode pre-scanning the measurement frequency range. Significant peaks are then marked
and then Quasi Peak detector mode re-measured.
(5) If the Peak Mode measured value compliance with and lower than Quasi Peak Mode Limit
Bellow 1 GHz, the EUT shall be deemed to meet QP Limits and then no additional QP Mode
measurement performed. But the Peak Value and average value both need to comply with
applicable limit above 1 GHz.
(6) Testing frequency range below 1GHz the measuring instrument use VBW=120 kHz with
Quasi-peak detection.
(7) Testing frequency range above 1GHz the measuring instrument use RBW=1 MHz and
VBW=3 MHz with Peak Detector for Peak Values, and use RBW=1 MHz and VBW=10 Hz
with Peak Detector for Average Values.
(8) For the actual test configuration, please see the test setup photo.

7.3 Test Procedure
(1) The EUT was directly connected to the spectrum analyzer and antenna output port as show
in the block diagram above.
(2) The bandwidth is measured at an amplitude level reduced 6dB from the reference level. The
reference level is the level of the highest amplitude signal observed from the transmitter at
the fundamental frequency. Once the reference level is established, the equipment is
conditioned with typical modulating signal to produce the worst –case (i.e the widest)
bandwidth.
(3)Measure the channel separation the spectrum analyzer was set to Resolution Bandwidth:100
kHz, and Video Bandwidth:300 kHz, Detector: Peak, Sweep Time set auto.
7.4 EUT Operating Condition
The EUT was set to continuously transmitting in each mode and low, middle and high channel
