3.0 System Test Configuration

3.1 Justification

The system was configured for testing in a typical fashion (as a customer would
normally use it), and in the confines as outlined in ANSI C63.10 (2013).

The EUT was powered by A.C. 120V, 60Hz during the test. Both designing schemes
have been considered, only the worst data was reported in this report.

For maximizing emissions below 30 MHz, the EUT was rotated through 360°, the centre
of the loop antenna was placed 1 meter above the ground, and the antenna
polarization was changed. For maximizing emissions, the EUT was rotated through
360°, the antenna height was varied from 1 meter to 4 meters above the ground
plane, and the antenna polarization was changed. This step by step procedure for
maximizing emissions led to the data reported in Section 4.

The rear of unit shall be flushed with the rear of the table.

The equipment under test (EUT) was configured for testing in a typical fashion (as a
customer would normally use it). The EUT was placed on a turn table, which enabled
the engineer to maximize emissions through its placement in the three orthogonal
axes.

3.2 EUT Exercising Software
The EUT exercise program (provided by client) used during testing was designed to
exercise the various system components in a manner similar to a typical use.
Test Software: Ampak RFTestTool, VER: 5.6

3.3 Special Accessories

No special accessories used.

3.4 Equipment Modification
Any modifications installed previous to testing by DONGGUAN TYSTART GLASS
TECHNOLOGY CO., LTD will be incorporated in each production model sold / leased in
the United States.

No modifications were installed by Intertek Testing Services Shenzhen Ltd. Longhua
Branch.

4.0 Emission Results

Data is included worst-case configuration (the configuration which resulted in the
highest emission levels).

4.1 Radiated Test Results

A sample calculation, configuration photographs and data tables of the emissions are
included.

4.1.1 Field Strength Calculation

The field strength is calculated by adding the reading on the Spectrum Analyzer to the
factors associated with preamplifiers (if any), antennas, cables, pulse desensitization
and average factors (when specified limit is in average and measurements are made
with peak detectors). A sample calculation is included below.

FS = RA + AF + CF - AG + PD + AV
Where FS = Field Strength in dBµV/m
RA = Receiver Amplitude (including preamplifier) in dBµV
CF = Cable Attenuation Factor in dB
AF = Antenna Factor in dB
AG = Amplifier Gain in dB
PD = Pulse Desensitization in dB
AV = Average Factor in -dB

In the radiated emission table which follows, the reading shown on the data table may
reflect the preamplifier gain. An example of the calculations, where the reading does
not reflect the preamplifier gain, follows:

FS = RA + AF + CF - AG + PD + AV

Assume a receiver reading of 62.0 dBµV is obtained. The antenna factor of 7.4 dB and
cable factor of 1.6 dB is added. The amplifier gain of 29 dB is subtracted. The pulse
desensitization factor of the spectrum analyzer was 0 dB, and the resultant average
factor was -10 dB. The net field strength for comparison to the appropriate emission
limit is 32 dBµV/m. This value in dBµV/m was converted to its corresponding level in
µV/m.

RA = 62.0 dBµV
AF = 7.4 dB
CF = 1.6 dB
AG = 29.0 dB
PD = 0 dB
AV = -10 dB
FS = 62 + 7.4 + 1.6 - 29 + 0 = 42 dBµV/m

Level in µV/m = Common Antilogarithm [(42 dBµV/m)/20] = 125.9 µV/m

3-meter distance were measured at 0.3-meter and an inverse proportional
extrapolation was performed to compare the signal level to the 3-meter limit. No
other harmonic emissions than those reported were detected at a test distance of
0.3-meter.

3. Negative value in the margin column shows emission below limit.

9.0 Miscellaneous Information

This miscellaneous information includes details of the measured bandedge, 20dB
Bandwidth, the test procedure and calculation of factor such as pulse desensitization.

9.1 Bandedge Plot

The test plots are attached as below. From the below plots, the field strength of any
emissions outside of the specified frequency band are attenuated to the general
radiated emission limits in section 15.209. It fulfils the requirement of 15.249(d).

Peak Measurement

Bandedge compliance is determined by applying marker-delta method, i.e
(Bandedge Plot).

(i) Lowest frequency channel (2402MHz):

Peak Resultant field strength = Fundamental emissions (peak value) – delta from the
bandedge plot

= 92.4 dBµv/m-50.79 dB
= 41.61 dBµv/m

Average Resultant field strength = Fundamental emissions (average value) – delta from
the bandedge plot

= 87.7 dBµv/m-50.79 dB
= 36.91 dBµv/m

(ii) Highest frequency channel (2480MHz):
Peak Resultant field strength = Fundamental emissions (peak value) – delta from the
bandedge plot

= 84.6 dBµv/m-49.76 dB
= 34.84 dBµv/m

Average Resultant field strength = Fundamental emissions (average value) – delta from
the bandedge plot

= 80.3 dBµv/m–49.76 dB
= 30.54 dBµv/m

The resultant field strength meets the general radiated emission limit in section
15.209, which does not exceed 74dBµv/m (Peak Limit) and 54dBµv/m (Average Limit).

9.3 Discussion of Pulse Desensitization

Pulse desensitivity is not applicable for this device since the transmitter transmits the
RF signal continuously.

9.4 Transmitter Duty Cycle Calculation, FCC Rule 15.35(b, c)

The EUT antenna output port was connected to the input of the spectrum analyzer.
The analyzer center frequency was set to EUT RF channel carrier. The SWEP function on
the analyzer was set to ZERO SPAN. The Transmitter ON time was determined from the
resultant time-amplitude display:

See attached spectrum analyzer chart (s) for Transmitter timing

See Transmitter timing diagram provided by manufacturer

x Not applicable, duty cycle was not used.

Test Report
Intertek Report No.: 190926001SZN-004
9.5 Emissions Test Procedures (cont'd)

The EUT is warmed up for 15 minutes prior to the test.

AC power to the unit is varied from 85% to 115% nominal and variation in the
fundamental emission field strength is recorded. If battery powered, a new, fully
charged battery is used.

Conducted measurements are made as described in ANSI C63.10 - 2013.

The IF bandwidth used for measurement of radiated signal strength was 10 kHz for
emission below 30 MHz and 120 kHz for emission from 30 MHz to 1000 MHz. Where
pulsed transmissions of short enough pulse duration warrant, a greater bandwidth is
selected according to the recommendations of Hewlett Packard Application Note
150-2. Above 1000 MHz, a resolution bandwidth of 1 MHz is used (RBW 3MHz used for
fundamental emission).

Transmitter measurements are normally conducted at a measurement distance of
three meters. However, to assure low enough noise floor in the restricted bands and
above 1 GHz, signals are acquired at a distance of one meter or less. All measurements
are extrapolated to three meters using inverse scaling, but those measurements taken
at a closer distance are so marked.
