2.2 DESCRIPTION OF TEST MODES
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 above was evaluated respectively.

Note:
(1) The measurements are performed at the highest, middle, lowest available channels.
(2) Fully-charged battery is used during the test
2.3 TABLE OF PARAMETERS OF TEXT 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

3.1.2 TEST PROCEDURE
a. 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.
b. 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.
c. I/O cables that are not connected to a peripheral shall be bundled in the center. The end of the
cable may be terminated, if required, using the correct terminating impedance. The overall
length shall not exceed 1 m.
d. LISN at least 80 cm from nearest part of EUT chassis.
e. For the actual test configuration, please refer to the related Item –EUT Test Photos.

3.1.5 EUT OPERATING CONDITIONS
The EUT was configured for testing in a typical fashion (as a customer would normally use it). The
EUT has been programmed to continuously transmit during test. This operating condition was
tested and used to collect the included data.
We pretest AC 120V and AC 240V, the worst voltage was AC 120V and the data recording in the
report.

3.2.2 TEST PROCEDURE
a. The measuring distance of at 3 m shall be used for measurements at frequency up to 25GHz.
For frequencies above 1GHz, any suitable measuring distance may be used.
b. The EUT was placed on the top of a rotating table 0.8 and 1.5 meters above the ground at a 3
meter semi-chamber test. The table was rotated 360 degrees to determine the position of the
highest radiation.
c. The height of the equipment or of the substitution antenna shall be 0.8 m; above 1GHz, the
height was 1.5m, the height of the test antenna shall vary between 1 m to 4 m. Both horizontal
and vertical polarizations of the antenna are set to make the measurement.
d. 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.
e. If the Peak Mode measured value compliance with and lower than Quasi Peak Mode Limit, the
EUT shall be deemed to meet QP Limits and then no additional QP Mode measurement
performed.
f. For the actual test configuration, please refer to the related Item –EUT Test Photos.
g. For the radiated emission test above 1GHz:
Place the measurement antenna away from each area of the EUT determined to be a source
of emissions at the specified measurement distance, while keeping the measurement antenna
aimed at the source of emissions at each frequency of significant emissions, with polarization
oriented for maximum response.
The measurement antenna may have to be higher or lower than the EUT, depending on the
radiation pattern of the emission and staying aimed at the emission source for receiving the
maximum signal. The final measurement antenna elevation shall be that which maximizes the
emissions. The measurement antenna elevation for maximum emissions shall be restricted to
a range of heights of from 1 m to 4 m above the ground or reference ground plane.
Note:
Both horizontal and vertical antenna polarities were tested
and performed pretest to three orthogonal axis. The worst case emissions were reported

5. 100 KHZ BANDWIDTH OF FREQUENCY BAND EDGE
APPLICABLE STANDARD
In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or
digitally modulated intentional radiator is operating, the radio frequency power that is
produced by the intentional radiator shall be at least 20 dB below that in the 100 kHz
bandwidth within the band that contains the highest level of the desired power, based on
either an RF conducted or a radiated measurement, provided the transmitter demonstrates
compliance with the peak conducted power limits. If the transmitter complies with the
conducted power limits based on the use of RMS averaging over a time interval, as
permitted under paragraph (b)(3) of this section, the attenuation required under this
paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in
§15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands,
as defined in §15.205(a), must also comply with the radiated emission limits specified in
§15.209(a)(c)
TEST PROCEDURE
a) Check the calibration of the measuring instrument using either an internal calibrator or a
known signal from an external generator.
b) Position the EUT without connection to measurement instrument. Turn on the EUT and
connect its antenna terminal to measurement instrument via a low loss cable. Then set it to
any one measured frequency within its operating range, and make sure the instrument is
operated in its linear range.
c) Set RBW to 100 kHz and VBW of spectrum analyzer to 300 kHz with a convenient frequency
span including 100 kHz bandwidth from band edge.
d) Measure the highest amplitude appearing on spectral display and set it as a reference level.
Plot the graph with marking the highest point and edge frequency.
e) Repeat above procedures until all measured frequencies were complete.
Note:
Both horizontal and vertical antenna polarities were tested
and performed pretest to three orthogonal axis. The worst case emissions were reported
