2.3.1 Conducted Emissions

The EUT is placed on the turntable, which is 0.8 m above ground plane. According to the requirements in
Section 6.2.1 of ANSI C63.10-2013 Conducted emissions from the EUT measured in the frequency range
between 0.15 MHz and 30MHz using Quasi-peak and average detector modes.

2.3.2 Radiated Emissions

The EUT is placed on a turn table, which is 0.8 m above ground plane. The turntable 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 maximum emissions, exploratory radiated emission measurements were made according to the
requirements in Section 6.3 of ANSI C63.10-2013

1. Measuring frequencies from 9k~10th harmonic (ex. 26GHz), No emission found between lowest
internal used/generated frequency to 30MHz.
2. Radiated emissions measured in frequency range from 9k~10th harmonic (ex. 26GHz) were made with
an instrument using Peak detector mode.
3. No emission was be recorded above 18GHz means the reading of emissions are attenuated more than
20dB below the permissible limits or the field strength is too small to be measured.

5.3. AC Power line conducted emissions
5.3.1 Standard Applicable

According to §15.207 (a): For an intentional radiator which is designed to be connected to the public utility
(AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any
frequency or frequencies within the band 150 kHz to 30 MHz shall not exceed 250 microvolts (The limit
decreases linearly with the logarithm of the frequency in the range 0.15 MHz to 0.50 MHz). The limits at
specific frequency range are listed as follows:

Frequency Range Limits (dBμV)
(MHz) Quasi-peak Average
0.15 to 0.50 66 to 56 56 to 46
0.50 to 5 56 46
5 to 30 60 50

* Decreasing linearly with the logarithm of the frequency

Premeasurement:
--- The turntable rotates from 0°to 315°using 45°steps.
--- The antenna is polarized vertical and horizontal.
--- The antenna height scan range is 1 meter to 2.5 meter.
--- At each turntable position and antenna polarization the analyzer sweeps with peak detection to find the
maximum of all emissions.

Final measurement:
--- The final measurement will be performed with minimum the six highest peaks.
--- According to the maximum antenna and turntable positions of premeasurement the software maximize
the peaks by changing turntable position (± 45°) and antenna movement between 1 and 4 meter. This
procedure is repeated for both antenna polarizations.
--- The final measurement will be done in the position (turntable, EUT-table and antenna polarization)
causing the highest emissions with Peak and Average detector.
--- The final levels, frequency, measuring time, bandwidth, turntable position, EUT-table position, antenna
polarization, correction factor, margin to the limit and limit will be recorded. Also a plot with the graph of
the premeasurement with marked maximum final measurements and the limit will be stored.

5.4.5. Measuring Instruments and Setting

Temperature 24.6℃ Humidity 51.6%
Test Engineer David Luo

PASS

Remark:
1. The other emission levels were very low against the limit.
2. The average measurement was not performed when the peak measured data under the limit of average
detection.
3. Detector AV is setting spectrum/receiver. RBW=1MHz/VBW=330Hz/Sweep time=Auto/Detector=Peak;
4. Please refer to following test plots;

5.5. Antenna Requirements
5.5.1 Standard Applicable

According to antenna requirement of §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 an
antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply
with the provisions of this Section. The manufacturer may design the unit so that a broken antenna can be
re-placed by the user, but the use of a standard antenna jack or electrical connector is prohibited. This
requirement does not apply to carrier current devices or to devices operated under the provisions of
Sections 15.211, 15.213, 15.217, 15.219, or 15.221. Further, this requirement does not apply to
intentional radiators that must be professionally installed, such as perimeter protection systems and some
field disturbance sensors, or to other intentional radiators which, in accordance with Section 15.31(d),
must be measured at the installation site. However, the installer shall be responsible for ensuring that the
proper antenna is employed so that the limits in this Part are not exceeded.

And according to §15.247(4)(1), system operating in the 2400-2483.5MHz bands that are used
exclusively for fixed, point-to-point operations may employ transmitting antennas with directional gain
greater than 6dBi provided the maximum peak output power of the intentional radiator is reduced by 1 dB
for every 3 dB that the directional gain of the antenna exceeds 6dBi.

5.5.2 Antenna Connected Construction
5.5.2.1. Standard Applicable

According to § 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.

5.5.2.2. Antenna Connector Construction

The directional gains of antenna used for transmitting is 5.5dBi, and the antenna is a PCB antenna
connect to PCB board and no consideration of replacement. Please see EUT photo for details.

5.5.2.3. Results: Compliance.
