2. System Test Configuration
2.1 EUT Configuration
The EUT configuration for testing is installed on RF field strength measurement to
meet the Commissions requirement and operating in a manner which intends to
maximize its emission characteristics in a continuous normal application.
2.2 EUT Exercise
The Transmitter was operated in the normal operating mode. The TX frequency was
fixed which was for the purpose of the measurements.
2.3 Test Procedure
2.3.1 Conducted Emissions
The EUT is a placed on as turn table which is 0.8 m above ground plane.
According to the requirements in Section 13.1.4.1 of ANSI C63.10-2013
Conducted emissions from the EUT measured in the frequency range between
0.15 MHz and 30 MHz using CISPR Quasi-Peak and average detector mode.
2.3.2 Radiated Emissions
The EUT is a placed on as turn table which is 0.8 m above ground plane. The
turn table shall rotate 360 degrees to determine the position of maximum
emission level. EUT is set 3m away from the receiving antenna which varied
from 1m to 4m to find out the highest emission. And also, each emission was to
be maximized by changing the polarization of receiving antenna both horizontal
and vertical. In order to find out the max. Emission, the relative positions of this
hand-held transmitter (EUT) was rotated through three orthogonal axes
according to the requirements in Section 13.1.4.1 of ANSI C63.10-2013.

3. Description of Test Modes
The EUT has been tested under its typical operating condition.
The EUT configuration for testing is installed on RF field strength measurement to meet the Commissions
requirement and operating in a manner which intends to maximize its emission characteristics in a
continuous normal application.
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.
Pre-defined engineering program for regulatory testing used to control the EUT for staying in continuous
transmitting and receiving mode is programmed.

9.1 Measurement Procedure
1. Below 1000MHz, The EUT was placed on a turn table which is 0.8m above
ground plane, And above 1000MHz, The EUT was placed on a styrofoam table which
is 1.5m above ground plane.
2. Maximum procedure was performed on the six highest emissions to ensure EUT
compliance.
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 measured was complete.

All emissions not reported were more than 20dB below the specified limit or in
the noise floor.
Note:
(1) All Readings are Peak Value and AV.
(2) Emission Level= Reading Level+Probe Factor +Cable Loss.
(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.

10. 6dB Bandwidth Test
10.1 Measurement Procedure
The EUT was operating in IEEE 802.11b, 802.11g, 802.11n(HT20), 802.11n(HT40) mode
or could be controlled its channel. Printed out the test result from the spectrum by hard
copy function.
1. Set resolution bandwidth (RBW) = 100 kHz.
2. Set the video bandwidth (VBW) ≥ 3 x RBW.
3. Detector = Peak.
4. Trace mode = max hold.
5. Sweep = auto couple.
6. Allow the trace to stabilize.
7. Measure the maximum width of the emission that is constrained by the frequencies
associated with the two outermost amplitude points (upper and lower frequency) that
are attenuated by 6 dB relative to the maximum level measured in the fundamental
emission.

11. Maximum Peak Output Power Test
11.1 Measurement Procedure
(1) According to FCC Part15.247(b)(3)
The maximum peak conducted output power may be measured using a broadband
peak RF power meter. The power meter shall have a video bandwidth that is greater than
or equal to the DTS bandwidth and shall utilize a fast-responding diode detector.
The testing follows FCC public Notice DA 00-705 Measurement Guidelines.
The RF output of EUT was connected to the power meter by RF cable and attnuator.
The path loss was compensated to the results for each measurement.
Set to the maximum output power setting and enable the EUT transmit continuously.
Measure the conducted output power with cable loss and record the results in the test
report.
Measure and record the results in the report.
(2) According to FCC Part 15.247(b)(4):
Conducted output power limit specified in paragraph (b) of this section is based on the
use of antennas with directional gains that do not exceed 6 dBi. If transmitting antennas of
directional gain greater than 6 dBi are used, the conducted output power from the
intentional radiator shall be reduced below the stated values in paragraphs (b)(3) of this
section, as appropriate, by the amount in dB that the directional gain of the antenna
exceeds 6 dBi.
Note: If antenna Gain exceeds 6 dBi, then Output power Limit=30-(Gain - 6)

Note:
1. For MIMO System of 802.11n(HT20) and 802.11n(HT40), total power is
calculated by combining the output power of each antenna according to
KDB662911.
2. Antenna 1 Gain: 4.57dBi, Antenna 2 Gain: 4.0dBi. For antennas with gains of
6dBi or less, maximum allowed Transmitter output watt(+30dBm)
3. In MIMO, Ant1+Ant2 Directional
Gain=GANT+10Log(N)dBi=4.57+10log(2)=7.01dBi.

12. Band Edge Test
12.1 Measurement Procedure
For Conducted Test
1. The testing follows FCC KDB Publication No. 558074 DTS D01 Meas. Guidance
v04.
2. 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.
3. Set to the maximum power setting and enable the EUT transmit continuously.
4. Set RBW = 100 kHz, VBW=300 kHz, Peak Detector. Unwanted Emissions measured
in any 100 kHz bandwidth outside of the authorized frequency band shall be
attenuated by at least 20 dB relative to the maximum in-band peak PSD level in 100
kHz when maximum peak conducted output power procedure is used. Measure and
record the results in the test report.
5. The RF fundamental frequency should be excluded against the limit line in the
operating frequency band.
For Radiated emission Test
1. The testing follows FCC KDB Publication No. 558074 DTS D01 Meas. Guidance
v04.
2. The EUT was arranged to its worst case and then tune the antenna tower (from 1 m
to 4 m) and turntable (from 0 degree to 360 degrees) to find the maximum reading. A
pre-amp and a high pass filter are used for the test in order to get better signal level.
3. The EUT was placed on a turntable with 0.8 meter above ground.
4. The EUT was set 3 meters from the interference receiving antenna, which was
mounted on the top of a variable height antenna tower.
5. Corrected Reading: Antenna Factor + Cable Loss + Read Level - Preamp Factor =
Level.
6. For measurement below 1GHz, If the emission level of the EUT measured by the
peak detector is 3 dB lower than the applicable limit, the peak emission level will be
reported. Otherwise, the emission measurement will be repeated using the
quasi-peak detector and reported.
7. Repeat above procedures until all frequency measured were complete.
When spectrum scanned above 1GHz setting resolution bandwidth 1MHz, video
bandwidth 3MHz.

15. Antenna Application
15.1 Antenna Requirement
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. And according to FCC 47 CFR
Section 15.247 (b), if transmitting antennas of directional gain greater than 6dBi are
used, the power shall be reduced by the amount in dB that the directional gain of the
antenna exceeds 6dBi.
15.2 Result
The EUT’S antenna, permanent attached antenna, is internal antenna. The antenna’s
gain is 4.0dBi and meets the requirement.
