been performed, traceable to National Primary Standards and International System of Units (SI).


Test Procedure
During the conducted emission test, the adapter was connected to the outlet of the LISN.

Maximizing procedure was performed on the six (6) highest emissions of the EUT.

All final data was recorded in the Quasi-peak and average detection mode.


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 §15.205 & §15.209 - RADIATED EMISSIONS TEST
Applicable Standard
As per FCC Part 15.209

 (a) Except as provided elsewhere in this subpart, the emissions from an intentional radiator shall not
exceed the field strength levels specified in the following table:

  Frequency (MHz)            Field strength (microvolts/meter)              Measurement distance (meters)
      0.009-0.490                        2400/F(kHz)                                        300

      **Except as provided in paragraph (g), fundamental emissions from intentional radiators operating under this
section shall not be located in the frequency bands 54-72 MHz, 76-88 MHz, 174-216 MHz or 470-806 MHz.
However, operation within these frequency bands is permItted under other sections of this part, e.g., §§15.231 and
15.241.


EUT Setup




The radiated emission tests were performed in the 3-meter chamber test site, using the setup accordance
with the ANSI C63.10-2013. The specification used was the FCC Part Subpart C limits.

The spacing between the peripherals was 10 cm.




FCC Part 15C                                                                                          Page 19 of 26


Bay Area Compliance Laboratories Corp. (Shenzhen)                               Report No.: RSZ181218001-00


EMI Test Receiver Setup
The system was investigated from 9 kHz to 1 GHz.

During the radiated emission test, the EMI test Receiver was set with the following configurations:

                       Frequency Range              RBW          Video B/W       Measurement
                        9 kHz – 150 kHz            200 Hz           1 kHz         QP/Average
                       150 kHz – 30 MHz             9 kHz           30 kHz        QP/Average
                      30 MHz – 1000 MHz            120 kHz         300 kHz            QP

The emission limits shown in the above table are based on measurements employing a CISPR quasi-peak
detector except for the frequency bands 9-90 kHz, 110-490 kHz and above 1000 MHz. Radiated emission
limits in these three bands are based on measurements employing an average detector.

If the maximized peak measured value complies with the limit, then it is unnecessary to perform an
QP/Average measurement


Corrected Amplitude & Margin Calculation
The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Loss, and subtracting the
Amplifier Gain from the Amplitude reading. The basic equation is as follows:

                  Corr. Ampl. = 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 - Corr. Ampl.
