FCC §15.107 – AC LINE CONDUCTED EMISSIONS
Applicable Standard
According to FCC §15.107


EUT Setup




The measurement procedure of EUT setup is according with per ANSI C63.4-2014. The related limit was
specified in FCC Part 15.107 Class B.

The spacing between the peripherals was 10 cm.

EMI Test Receiver Setup
The EMI test receiver was set to investigate the spectrum from 150 kHz to 30 MHz.

During the conducted emission test, the EMI test receiver was set with the following configurations:

                              Frequency Range                      IF B/W
                              150 kHz – 30 MHz                      9 kHz


Test Procedure
During the conducted emission test, the host PC was connected to the first LISN and the other relevant
equipments were conncected to the second LISN.
Maximizing procedure was performed on the six (6) highest emissions of the EUT.

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

FCC Part 15B, Class B                                                                       Page 9 of 19

Corrected Factor & Margin Calculation
The Corrected factor is calculated by adding LISN/ISN 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 15.107,

Refer to CISPR16-4-2:2011 and CISPR 16-4-1:2009, the measured level is in compliance 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.

Test Procedure
Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all
installation combinations.
All data was recorded in the Quasi-peak detector mode from 30 MHz to 1 GHz and PK and average
detector modes for frequencies above 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 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 data in the following table, the EUT complied with the FCC §15.109 Class B,

Refer to CISPR16-4-2:2011 and CISPR 16-4-1:2009, the measured level is in compliance 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.
