FCC§15.203 - ANTENNA REQUIREMENT
Applicable Standard
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. 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 replaced by the user, but the user of a standard antenna jack or electrical connector
is prohibited. The structure and application of the EUT were analyzed to determine compliance with
section §15.203 of the rules. §15.203 state that the subject device must meet the following criteria:
a. Antenna must be permanently attached to the unit.
b. Antenna must use a unique type of connector to attach to the EUT.
Unit must be professionally installed, and installer shall be responsible for verifying that the correct
antenna is employed with the unit.
Antenna Connector Construction
The EUT has an external antenna arrangement, which with a non-standard jack and the antenna gain is
0 dBi, fulfill the requirement of this section. Please refer to the EUT photos.
Result: Compliance.

Corrected Factor & Margin Calculation
The Corrected factor is calculated by adding LISN VDF (Voltage Division Factor), Cable Loss and
Transient Limiter Attenuation. The basic equation is as follows:
Correction Factor = LISN VDF + Cable Loss + Transient Limiter Attenuation
The “Margin” column of the following data tables indicates the degree of compliance with the applicable
limit. For example, a margin of 7 dB means the emission is 7 dB below the limit. The equation for margin
calculation is as follows:
Margin = Limit – Corrected Amplitude
Test Results Summary
According to the recorded data in following table, the EUT complied with the FCC Part 15.207,
Refer to CISPR16-4-2:2011 and CISPR 16-4-1:2009, the measured level complies with the limit if
Lm + U(Lm) ≤ Llim + Ucispr
In BACL, U(Lm) is less than Ucispr, if Lm is less than Llim, it implies that the EUT complies with the limit.

FCC §15.209 & §15.237 (c) - SPURIOUS EMISSIONS
Applicable Standard
FCC §15.209 & §15.237 (c)
(c) The field strength within the permitted 200 kHz band shall not exceed 80 millivolts/meter at 3 meters.
The field strength of any emissions radiated on any frequency outside of the specified 200 kHz band shall
not exceed the general radiated emissions limits specified in §15.209. The emission limits in this paragraph
are based on measurement instrumentation employing an average detector. The provisions in §15.35 for
limiting peak emissions apply.

The radiated emission tests were performed in the 3 meters test site, using the setup accordance with the
ANSI C63.10-2013. The specification used was the FCC 15.209, and FCC 15.237 limits.
EMI Test Receiver & Spectrum Analyzer Setup
The system was investigated from 30 MHz to 1 GHz.

Test Procedure
Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all
installation combinations.
Data was recorded in Quasi-peak detection mode for frequency range of 30 MHz-1 GHz.
Corrected Amplitude & Margin Calculation
The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Loss, and subtracting the
Amplifier Gain from the Meter Reading. The basic equation is as follows:
Corrected Amplitude = Meter Reading + Antenna Factor + Cable Loss - Amplifier Gain
The “Margin” column of the following data tables indicates the degree of compliance with the applicable
limit. For example, a margin of 7dB means the emission is 7dB below the limit. The equation for margin
calculation is as follows:
Margin = Limit – Corrected Amplitude
Test Results Summary
According to the recorded data in following table, the EUT complied with the FCC Title 47, Part 15,
Subpart C, section 15.209 and 15.237.
Refer to CISPR16-4-2:2011 and CISPR 16-4-1:2009, the measured level complies with the limit if
Lm + U(Lm) ≤ Llim + Ucispr
In BACL, U(Lm) is less than Ucispr, if Lm is less than Llim, it implies that the EUT complies with the limit.

FCC §15.237(b) – 20 dB EMISSION BANDWIDTH
Applicable Standard
(b) Emissions from the intentional radiator shall be confined within a band 200 kHz wide centered on the
operating frequency. The 200 kHz band shall lie wholly within the above specified frequency ranges.
Test Procedure
1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal
from an external generator.
2. Position the EUT without connection to measurement instrument. Turn on the EUT and connect it to
measurement instrument. Then set it to any one convenient frequency within its operating range. Set a
reference level on the measuring instrument equal to the highest peak value.
3. Measure the frequency difference of two frequencies that were attenuated 20 dB from the reference
level. Record the frequency difference as the emission bandwidth.
4. Repeat above procedures until all frequencies measured were complete.
Test Data
Environmental Conditions
Temperature:
25 ℃
Relative Humidity:
