5.1. Antenna requirement
Requirement
FCC CFR Title 47 Part 15 Subpart C 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 anantenna
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 6 dBi 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 6 dBi.
Test Result:
Passed
Not Applicable
The directional gain of the antenna less than 6 dBi, please refer to the below antenna photo.

TEST CONFIGURATION
TEST PROCEDURE
1. The EUT was setup according to ANSI C63.10:2013 requirements.
2. The EUT was placed on a platform of nominal size, 1 m by 1.5 m, raised 80 cm above the conducting
ground plane. The vertical conducting plane was located 40 cm to the rear of the EUT. All other surfaces
of EUT were at least 80 cm from any other grounded conducting surface.
3. The EUT and simulators are connected to the main power through a line impedances stabilization
network (LISN). The LISN provides a 50 ohm /50uH coupling impedance for the measuring equipment.
4. The peripheral devices are also connected to the main power through a LISN. (Please refer to the block
diagram of the test setup and photographs)
5. Each current-carrying conductor of the EUT power cord, except the ground (safety) conductor,was
individually connected through a LISN to the input power source.
6. The excess length of the power cord between the EUT and the LISN receptacle were folded back and
forth at the center of the lead to form a bundle not exceeding 40 cm in length.
7. Conducted emissions were investigated over the frequency range from 0.15MHz to 30MHz using a
receiver bandwidth of 9 kHz.
8. During the above scans, the emissions were maximized by cable manipulation.

The EUT is placed on a turn table which is 1.5 meter above ground. The turn table is rotated 360 degrees
to determine the position of the maximum emission level.
The EUT waspositioned such that the distance from antenna to the EUT was 3 meters.
The antenna is scanned from 1 meter to 4 meters to find out the maximum emission level. Thisis
repeated for both horizontal and vertical polarization of the antenna. In order to find the maximum
emission, all of the interface cables were manipulated according to ANSI C63.10:2013 on radiated
measurement.
The receiver set as follow:
RBW=1 MHz, VBW=3 MHz Peak detector for Peak value
RBW=1 MHz, VBW=10 Hz Peak detector for Average value.

The EUT was tested according to ANSI C63.10:2013.
The EUT is placed on a turn table with 0.8 meter above ground for below 1GHz, 1.5 meter above ground
for above 1GHz.
The EUT was set 3 meters from the receiving antenna, which was mounted on the top of a variable
height antenna tower.
For each suspected emission, 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 to comply with the guidelines.
Set to the maximum power setting and enable the EUT transmit continuously.
Use the following spectrum analyzer settings
(1) Span shall wide enough to fully capture the emission being measured;
(2) Below 1 GHz:
RBW=120 kHz, VBW=300 kHz, Sweep=auto, Detector function=peak, Trace=max hold;
If the emission level of the EUT measured by the peak detectoris 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.
(3) From 1 GHz to 10th harmonic:
RBW=1 MHz, VBW=3 MHz Peak detector for Peak value
RBW=1 MHz, VBW=10 Hz Peak detector for Average value.
TEST MODE:
Please refer to the clause 3.3
TEST RESULTS
Passed
Not Applicable
Note:
1) Final Level = Receiver Read level + Antenna Factor + Cable Loss – Preamplifier Factor
2) The emission levels of other frequencies are very lower than the limit and not show in test report.
3) Below 1 GHz,Have pre-scan all modulation mode, found the GFSK modulation High channel which it was
worst case, so only the worst case’s data on the test report.
4) Above 1 GHz,Have pre-scan all modulation mode, found the GFSK modulation which it was worst case,
so only the worst case’s data on the test report
5) The peak level is lower than average limit(54 dBuV/m), this data is the too weak instrument of signal is
unable to test.
 9 kHz ~ 30 MHz
The low frequency, which started from 9 kHz to 30 MHz, was pre-scanned and the result which was
20 dB lower than the limit line per 15.31(o) was not reported.
