3.5 Statement of the measurement uncertainty
The data and results referenced in this document are true and accurate. The reader is cautioned that there
may be errors within the calibration limits of the equipment and facilities. The measurement uncertainty was
calculated for all measurements listed in this test report acc. to CISPR 16 - 4 „Specification for radio
disturbance and immunity measuring apparatus and methods – Part 4: Uncertainty in EMC
Measurements“ and is documented in the Shenzhen Global Test Service Co.,Ltd quality system acc. to DIN
EN ISO/IEC 17025. Furthermore, component and process variability of devices similar to that tested may
result in additional deviation. The manufacturer has the sole responsibility of continued compliance of the
device.
Hereafter the best measurement capability for Shenzhen GTS laboratory is reported:

TEST PROCEDURE
1 The equipment was set up as per the test configuration to simulate typical actual usage per the user’s
manual. The EUT is a tabletop system, a wooden table with a height of 0.8 meters is used and is placed on
the ground plane as per ANSI C63.10-2013.
2 Support equipment, if needed, was placed as per ANSI C63.10-2013
3 All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10-2013
4 The EUT received DC 12V power from adapter, the adapter received AC120V/60Hz and AC 240V/60Hz
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.
8 During the above scans, the emissions were maximized by cable manipulation.
AC Power Conducted Emission Limit
For intentional device, according to § 15.207(a) AC Power Conducted Emission Limits is as following：
Frequency range (MHz)

TEST PROCEDURE
1. The EUT was placed on a turn table which is 0.8m above ground plane when testing
frequency range 9 KHz –1GHz;the EUT was placed on a turn table which is 1.5m above
ground plane when testing frequency range 1GHz – 25GHz.
2. 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.
4. Repeat above procedures until all frequency measurements have been completed.
5. Radiated emission test frequency band from 9KHz to 25GHz.

Field Strength Calculation
The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting the
Amplifier Gain and Duty Cycle Correction Factor(if any) from the measured reading. The basic equation with a
sample calculation is as follows:
FS = RA + AF + CL - AG
Where FS = Field Strength
CL = Cable Attenuation Factor (Cable Loss)
RA = Reading Amplitude
AG = Amplifier Gain
AF = Antenna Factor
Transd=AF +CL-AG
RADIATION LIMIT
For intentional device, according to § 15.209(a), the general requirement of field strength of radiated emission
from intentional radiators at a distance of 3 meters shall not exceed the following table. According to §
15.247(d), in any 100kHz bandwidth outside the frequency band in which the EUT is operating, the radio
frequency power that is produced by the intentional radiator shall be at least 20dB below that in the100kHz
bandwidth within the band that contains the highest level of desired power.
The pre-test have done for the EUT in three axes and found the worst emission at position shown in test setup
photos.

4.4 Power Spectral Density
Limit
For digitally modulated systems, the power spectral density conducted from the intentional radiator to the
antenna shall not be greater than 8 dBm in any 3 kHz band during any time interval of continuous
transmission.
Test Procedure
1. Use this procedure when the maximum peak conducted output power in the fundamental emission is used
to demonstrate compliance.
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.

4.5 6dB Bandwidth
Limit
For digital modulation systems, the minimum 6 dB bandwidth shall be at least 500 kHz
Test Procedure
The transmitter output was connected to the spectrum analyzer through an attenuator. The bandwidth of the
fundamental frequency was measured by spectrum analyzer with 100 KHz RBW and 300 KHz VBW. The 6dB
bandwidth is defined as the total spectrum the power of which is higher than peak power minus 6dB.

4.6 Out-of-band Emissions
Limit
In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated
device is operating, the RF power that is produced 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 that the transmitter demonstrates compliance with the
peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of
root-mean-square averaging over a time interval, as permitted under Section (b)(3) of §15.247 and RSS 5.4(4),
the attenuation required shall be 30 dB instead of 20 dB. Attenuation below the general field strength limits
specified in §15.209(a) and RSS-Gen are not required.
Test Procedure
Connect the transmitter output to spectrum analyzer using a low loss RF cable, and set the spectrum analyzer
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.

4.7 Antenna Requirement
Standard Applicable
For intentional device, according to FCC 47 CFR Section 15.203:
An intentional radiator shall be designed to ensure that no antenna other than that furnished by the
responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna
that uses a unique coupling to the intentional radiator, the manufacturer may design the unit so that a broken
antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is
prohibited
FCC CFR Title 47 Part 15 Subpart C Section 15.247(c) (1) (I):
(i) Systems operating in the 2400-2483.5 MHz band that is used exclusively for fixed. Point-to-point operations
may employ transmitting antennas with directional gain greater than 6dBi provided the maximum conducted
output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the
antenna exceeds 6dBi.
Test Result:
The maximum gain of antenna was 3dBi for 2.4GHz WIFI.
