5.1 Test Configurations
Test software “MTK MT7637 QA V0.0.1.63, Indium QA Tool V1.17, V1.19” provided by the
customer was used to program the EUT to transmit continuously.
All modes of operation were investigated initially with full testing performed on the worst-case
modes. This report contains data from the following worst-case modes of operation:
802.11g: 6Mbps
802.11n: MCS0
5.2 Environmental Conditions
Ambient air temperature of the test site was within the range of 10 ⁰C to 40 ⁰C (50 ⁰F to 104 ⁰F)
unless the EUT specified testing over a different temperature range. Humidity levels were in the
range of 10% to 90% relative humidity. Testing conditions were within tolerance, and any
deviations required from the EUT are reported.
5.3 Antenna Requirements
The antennas are permanently attached and there are no provisions for connection to an
external antenna.
5.4 Modifications
No modifications were made during testing.
5.5 Dates of Testing
Testing was performed from March 26, 2018 to May 21, 2018.

8 Test Site Description
8.1 Radiated Emissions Test Site
Radiated measurements are performed in a 3m semi-anechoic chamber, which meets NSA
requirements for the frequency range of 30MHz to 1000MHz. For measurements above 1 GHz,
absorbers are placed on the ground plane between the receiving antenna and the EUT to meet
Site VSWR requirements in accordance with ANSI C63.4:2014.
Testing below 30MHz is also performed in the semi-anechoic chamber. Per KDB 414788,
comparison measurements were performed between an open area site and the semi-anechoic
chamber and the results from the chamber is higher than those measured from the open area
site.
Radiated Measurements in 9kHz- 30 MHz
The EUT is positioned on a turntable at a height of 80cm using a non-conducting table. A loop
antenna is positioned at 3m from the EUT periphery at 1m height from the ground. The turntable
is rotated 360 degrees to determine the highest emissions. This is repeated for three
orientations of the measurement antenna- parallel, perpendicular and ground-parallel. All
possible orientations of the EUT were investigated for emissions and the flat orientation was
identified as the worst-case configuration.
Radiated Measurements in 30 MHz - 1000 MHz
The EUT is positioned on a turntable at a height of 80cm using a non-conducting table. A
linearly polarized broadband antenna is positioned at 3m from the EUT periphery. The turntable
is rotated 360 degrees and the antenna height varied from 1m to 4m to determine the highest
emissions. This is repeated for both horizontal and vertical polarizations of the measurement
antenna. All possible orientations of the EUT were investigated for emissions and the flat
orientation was identified as the worst-case configuration.
Radiated Measurements above 1GHz
The EUT is positioned on a Turntable at a height of 1.5m. A Linearly polarized antenna is
positioned at 3m from the EUT periphery. Guidelines in ANSI C63.10:2013 were followed with
respect to maximizing the emissions. The measurement antenna is set at a fixed 1.5m height
while the turntable is rotated 360 degrees and the EUT elevation angle is varied from 0 to 150
degrees in 30 degree increments to determine the highest emissions. This is repeated for both
horizontal and vertical Polarizations of the Measurement Antenna. Measurements above 18GHz
were performed at a 3m distance. Near field scanning is performed to identify frequencies
above 1 GHz.

8.2 Antenna port conducted measurements
All antenna port conducted measurements were performed on a bench-top setup consisting of a
spectrum analyzer, power meter (as necessary), splitters/combiners (as necessary),
attenuators, and pre-characterized RF cables.
The correction factors between the EUT and the spectrum analyzer were added internally in the
analyzer settings, where applicable. The plots displayed take these correction factors into
account.

9.7 Conducted Band Edge Emissions
Test Requirement:
FCC CFR 47 Rule Part 15.247 (d)
ISED RSS-247 [5.5]
Test Method:
Measurements were performed according to the procedure defined in KDB 558074 - Guidance
for Performing Compliance Measurements on Digital Transmission Systems (DTS) Operating
Under §15.247 V04 and ANSI C63.10 2013.
Spectrum analyzer settings:
Span = wide enough to capture the peak level of the emission operating on the channel closest
to the band edge, as well as any modulation products which fall outside of the authorized band

The trace was allowed to stabilize. The marker was set on the emission at the band edge, or on
the highest modulation product outside of the band, if this level is greater than that at the band
edge. The delta marker function was set and the marker-to-peak function moved to the peak of
the in-band emission.
Limits:
All spurious emissions at least 20 dBc.
Test Result:
Pass.

Test Requirement:
FCC CFR 47 Rule Part 15.247 (d)
ISED RSS-247 [5.5] and RSS GEN [8.9]
Test Method:
Measurements were performed according to the procedure defined in KDB 558074 - Guidance
for Performing Compliance Measurements on Digital Transmission Systems (DTS) Operating
Under §15.247 V04 and ANSI C63.10: 2013.
Radiated spurious measurements are made from 9kHz to the 10th harmonic of the fundamental
frequency of the transmitter. The limit for radiated spurious emissions is per 15.209 and RSS247 [5.5]. Additionally, emissions found in the restricted bands as listed in 15.205 were tested
for compliance per limits in 15.209 and RSS-Gen.
The EUT was tested near the low, middle and high channels of operation in each sub band.
Guidelines in ANSI C63.10:2013 were followed with respect to maximizing the emissions.
A pre-amp and a high pass filter were required for this test to provide the measuring system with
sufficient sensitivity. The peak reading of the emission, after being corrected by the antenna
factor, cable loss, pre-amp gain, etc., is the peak field strength.
Both horizontal and vertical antenna polarizations were investigated. Worst-case maximized
data for both polarizations is shown in this test report.

9.9 AC Line Conducted Emissions
Test Requirements
FCC CFR 47 Rule Part 15.207 (a)
Innovation Science and Economic Development Canada RSS-Gen [8.8]
Test Method
Conducted power line measurements are made, unless otherwise specified, over the frequency
range from 150 kHz to 30 MHz to determine the unsymmetric radio-noise voltage that is
conducted from the EUT power-input terminals that are directly (or indirectly via separate
transformer or power supplies) connected to a public power network. Equipment is tested with
the power cords that are used under normal operating conditions. These measurements are
made using a LISN (Line Impedance Stabilization Network). AC powered peripherals are
attached to a second LISN with the 50 ohm measuring port terminated by a 50 ohm resistive
load.
The EUT is set to continuously transmit on Ch.6, 802.11g mode at max power settings.
Measurements from the USB-C port reported here.
EMI Receiver Settings:
150 kHz – 30 MHz:
RBW= 9 kHz
VBW ≥ 3 X RBW
Trace Mode: Peak Detector (Max Hold).
Final measurements performed using Quasi-Peak and Average Detectors.
Span= 150 kHz – 30 MHz
Sweep time= Auto
