TEST CONDITIONS AND RESULTS
3.1 CONDUCTED EMISSIONS TEST
Limit
According to FCC CFR Title 47 Part 15 Subpart C Section 15.207, AC Power Line Conducted Emissions Limits
for Licence-Exempt Radio Apparatus as below:
* Decreasing linearly with the logarithm of the frequency
For intentional device, according to §15.207(a) Line Conducted Emission Limit is same as above table.
Test Setup
Test Procedure
1,The equipment was set up as per the test configuration to simulate typical actual usage per the user’s
manual. A wooden table with a height of 0.8 meters is used and is placed on the ground plane as per
ANSI C63.10.
2, Support equipment, if needed, was placed as per ANSI C63.10.
3, All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10.
4, If a EUT received DC power from the USB Port of Notebook PC, the PC’s adapter received AC power
through a Line Impedance Stabilization Network (LISN) which supplied power source and was grounded
to the ground plane.
5, All support equipments received AC power from a second LISN, if any.
6, The EUT test program was started. Emissions were measured on each current carrying line of the EUT
using a spectrum Analyzer / Receiver connected to the LISN powering the EUT. The LISN has two
monitoring points: Line 1 (Hot Side) and Line 2 (Neutral Side). Two scans were taken: one with Line 1
connected to Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line 1
connected to a 50 ohm load and Line 2 connected to the Analyzer / Receiver.
7, Analyzer / Receiver scanned from 150 KHz to 30MHz for emissions in each of the test modes.
Test Result
Not applicable, the device is powered by battery.

3.2 RADIATED EMISSION TEST
Limit
For intentional device, according to § 15.209(a), the general requirement of field strength of radiated
emission out of authorized band shall not exceed the following table at a 3 meters measurement
distance.
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)
Except when the requirements applicable to a given device state otherwise, emissions from licence‑
exempt transmitters shall comply with the field strength limits shown in table below. Additionally, the
level of any transmitter emission shall not exceed the level of the transmitter’s fundamental emission
Unwanted emissions that fall into restricted bands shall comply with the limits specified in RSS-Gen;
and Unwanted emissions that do not fall within the restricted frequency bands shall comply either with
the limits specified in the applicable RSS or with those specified in this RSS-Gen.

Test Procedure
1.
2.
Below 1GHz measurement the EUT is placed on a turntable which is 0.8m above ground plane,
and above 1GHz measurement EUT was placed on a low permittivity and low loss tangent turn
table which is 1.5m above ground plane.
Maximum procedure was performed by raising the receiving antenna from 1m to 4m and rotating
the turn table from 0℃ to 360℃ to acquire the highest emissions from EUT
3.
And also, each emission was to be maximized by changing the polarization of receiving antenna
both horizontal and vertical.

5.
6.
Repeat above procedures until all frequency measurements have been completed.
Radiated emission test frequency band from 9KHz to 25GHz.

TEST RESULTS
---PASS--Remark:
1.
All the test modes completed for test. The worst case of Radiated Emissionis Middle channel, the
test data of this mode was reported.
2. By preliminary testing and verifying three axis (X, Y and Z) position of EUT transmitted status, it
was found that “Z axis” position was the worst, and test data recorded in this report.
3. Radiated emission test from 9KHz to 10th harmonic of fundamental was verified, and no emission
found except system noise floor in 9KHz to 30MHz and not recorded in this report.

Remark:
(1) Measuring frequencies from 1 GHz to the 25 GHz.
(2) Factor = Antenna Factor + Cable Loss – Pre-amplifier.
(3) Margin= Limits –Emission Level
(4) Data of measurement within this frequency range shown “--- ” in the table above means the reading of
emissions are attenuated more than 20dB below the permissible limits or the field strength is too small to be
measured.
(5) When the test results of Peak Detected below the limits of Average Detected, the Average Detected is not
need completed. For example: Top Channel at Fundamental 73.16dBuV/m(PK Value) <93.98(AV Limit), at
harmonic 53.20 dBuV/m(PK Value) <54 dBuV/m(AV Limit), the Average Detected not need to completed.
(6) All modes of operation were investigated and the worst-case emissions are reported.

2. Set the RBW ≥ 3 kHz.
3. Set the VBW ≥ 3× RBW.
4. Set the span to 1.5 times the DTS channel bandwidth.
5. Detector = peak.
6. Sweep time = auto couple.
7. Trace mode = max hold.
8. Allow trace to fully stabilize.
9. Use the peak marker function to determine the maximum power level.
10. If measured value exceeds limit, reduce RBW (no less than 3 kHz) and repeat.
11. The resulting peak PSD level must be 8dBm.

3.6 OUT-OF BAND EMISSIONS
Limit
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
desiredpower, based on either an RF con-ducted or a radiated measurement, pro-vided the transmitter
demonstrates compliance with the peak conducted power limits. If the transmitter com-plies 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.
Test Procedure
Connect the transmitter output to spectrumanalyzer using a low loss RF cable, and set the spectrumanalyzer to
RBW=100 kHz, VBW= 300 kHz, peak detector, and max hold. Measurements utilizing these setting are made of
the in-band reference level, bandedge and out-of-band emissions.

Remark: The measurement frequency range is from 30MHz to the 10th harmonic of the fundamental frequency.
The lowest, middle and highest channels are tested to verify the spurious emissions and bandage measurement
