5 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.
The Transmitter was operated in the normal operating mode. The TX frequency was fixed which was for the
purpose of the measurements.
Test of channel included the lowest and middle and highest frequency to perform the test, then record on this
report.
Those data rates (802.11b: 1 Mbps; 802.11g: 6 Mbps; 802.11n (HT20): MCS0; 802.11n (HT40): MCS0) were
used for all test.
The EUT was pretested with 3 orientations placed on the table for the radiated emission measurement X, Y,
and Z-plane. The Y-plane results were found as the worst case and were shown in this report.

7.2.5 Test Procedure
The test site semi-anechoic chamber has met the requirement of NSA tolerance 4 dB according to the
standards: ANSI C63.10-2013. The test distance is 3m.The setup is according to the requirements in Section
13.1.4.1 of ANSI C63.10-2013 and CAN/CSA-CEI/IEC CISPR 22.
This test is required for any spurious emission that falls in a Restricted Band, as defined in Section 15.205.
It must be performed with the highest gain of each type of antenna proposed for use with the EUT.
Use the following spectrum analyzer settings:

a.
The measuring distance of at 3 m shall be used for measurements at frequency up to 1GHz and
frequencies above 1GHz,
b.
The EUT was placed on the top of a rotating table 0.8 m for below 1GHz and 1.5m for above 1GHz the
ground at a
3 meter. 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 for below 1GHz and 1.5m for
above 1GHz; 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.
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.
e.
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.
f.
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.
g
For the actual test configuration, please refer to the related Item EUT Test Photos.
Note:
Both horizontal and vertical antenna polarities were tested
and performed pretest to three orthogonal axis. The worst case emissions were reported
During the radiated emission test, the Spectrum Analyzer was set with the following configurations:
For peak measurement:
Set RBW=100 kHz for f < 1 GHz; VBWıRBW; Sweep = auto; Detector function = peak; Trace = max hold;
Set RBW = 1 MHz, VBW= 3MHz for fı1 GHz
For average measurement:
VBW = 10 Hz, when duty cycle is no less than 98 percent.
VBW ı 1/T, when duty cycle is less than 98 percent where T is the minimum transmission duration over
which the transmitter is on and is transmitting at its maximum power control level for the tested mode of
operation.

N2016.11.05.1105.V.1.1
Note: for the frequency ranges below 30 MHz, a narrower RBW is used for these ranges but the measured
value should add a RBW correction factor (RBWCF) where RBWCF [dB] =10*lg(100 [kHz]/narrower RBW
[kHz]). , the narrower RBW is 1 kHz and RBWCF is 20 dB for the frequency 9 kHz to 150 kHz, and the
narrower RBW is 10 kHz and RBWCF is 10 dB for the frequency 150 kHz to 30 MHz.

Note: (1) All Readings are Peak Value (VBW=3MHz) and Peak Value (VBW=10Hz).
(2) Emission Level= Antenna Factor + Cable Loss + Read Level - Preamp Factor
(3) 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.
(4)802.11b mode is the worst mode. When PK value is lower than the Average value limit, average
don't record.

According to KDB 558074)6)b), issued 06/09/2015
7.5.2 Conformance Limit
No limit requirement.
7.5.3 Measuring Instruments
The Measuring equipment is listed in the section 6.3 of this test report.
7.5.4 Test Setup
Please refer to Section 6.1 of this test report.
7.5.5 Test Procedure
The zero-span mode on a spectrum analyzer or EMI receiver if the response time and spacing between bins
on the sweep are sufficient to permit accurate measurements of the on and off times of the transmitted signal.
Set the center frequency of the instrument to the center frequency of the transmission. Set RBW ı OBW if
possible; otherwise, set RBW to the largest available value. Set VBW ı RBW. Set detector = peak or
average. The zero-span measurement method shall not be used unless both RBW and VBW are > 50/T and
the number of sweep points across duration T exceeds 100. (For example, if VBW and/or RBW are limited to
3 MHz, then the zero-span method of measuring duty cycle shall not be used if T İ 16.7 microseconds.)
The transmitter output is connected to the Spectrum Analyzer. We tested accroding to the zero-span
measurement method, 6.0)b) in KDB 558074(issued 06/09/2015)
The largest availble value of RBW is 8 MHz and VBW is 50 MHz. The zero-span method of measuring duty
cycle shall not be used if T İ 6.25 microseconds. (50/6.25 = 8)
The zero-span method was used because all measured T data are > 6.25 microseconds and both RBW and
VBW are > 50/T.
The RF output of EUT was connected to the spectrum analyzer by RF cable and attenuator.
The path loss was compensated to the results for each measurement.
Set to the maximum power setting and enable the EUT transmit continuously.
The EUT was operating in controlled its channel.
Use the following spectrum analyzer settings:
Span = Zero Span
RBW = 8MHz(the largest available value)
VBW = 8MHz (t RBW)
Number of points in Sweep >100
Detector function = peak
Trace = Clear write
Measure Ttotal and Ton
Calculate Duty Cycle = Ton / Ttotal

1. Test procedures refer KDB 558074 D01 v03r05 section 9.2.3.2 Measurement using a power meter
(PM).
2. Alternatively, measurements may be performed using a wideband gated RF power meter provided that
the gate parameters are adjusted such that the power is measured only when the EUT is transmitting at its
maximum power control level. Since this measurement is made only during the ON time of the transmitter,
no duty cycle correction is required.
3. Multiple antenna system was performed in accordance with KDB 662911 D01 v02r01 Emissions
Testing of Transmitters with Multiple Outputs in the Same Band.

7.7.5 Test Procedure
The testing follows Measurement Procedure 10.3 Method AVGPSD of FCC KDB Publication No. 558074
D01 DTS Meas. Guidance v03r05
This procedure may be used when the maximum (average) conducted output power was used to
demonstrate compliance to the output power limit. This is the baseline method for determining the maximum
(average) conducted PSD level. If the instrument has an RMS power averaging detector, it must be used;
otherwise, use the sample detector. The EUT must be configured to transmit continuously (duty cycle
98%); otherwise sweep triggering/signal gating must be implemented to ensure that measurements are
made only when the EUT is transmitting at its maximum power control level (no transmitter off time is to be
considered).
The RF output of EUT was connected to the spectrum analyzer by RF cable and attenuator.
The path loss was compensated to the results for each measurement.
Set to the maximum power setting and enable the EUT transmit continuously.
The EUT was operating in controlled its channel.
a) Set instrument center frequency to DTS channel center frequency.
b) Set span to at least 1.5 times the OBW.
c) Set RBW to: 3 kHz RBW 100 kHz. .
d) Set VBW 3 x RBW.
e) Detector = power averaging (RMS) or sample detector (when RMS not available).
f) Ensure that the number of measurement points in the sweep 2 x span/RBW.
g) Sweep time = auto couple.
h) Employ trace averaging (RMS) mode over a minimum of 100 traces.
i) Use the peak marker function to determine the maximum amplitude level.
j) If measured value exceeds limit, reduce RBW (no less than 3 kHz) and repeat (note that this may require
zooming in on the emission of interest and reducin
