purpose of the measurements.
According to its specifications, the EUT must comply with the requirements of the
Section 15.203, 15.205, 15.207, 15.209 and 15.249 under the FCC Rules Part 15
Subpart C.

2.3. General Test Procedures
2.3.1 Conducted Emissions (N/A)
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

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

Notes:
1. Measuring frequencies from 9k~10th harmonic (ex. 10GHz), No emission found between lowest internal used/generated
frequency to 30 MHz.
2. Radiated emissions measured in frequency range from 9k~10th harmonic (ex. 10GHz) were made with an instrument
using Peak detector mode.

10.AC Power line conducted emissions

10.1 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 is 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
