Bay Area Compliance Laboratories Corp. (Dongguan)                       Report No.: R2DG130314004-00A

FCC §15.107 – AC LINE CONDUCTED EMISSIONS
Measurement Uncertainty
Compliance or non- compliance with a disturbance limit shall be determined in the following manner:

If Ulab is less than or equal to Ucispr of Table 1, then:
–compliance is deemed to occur if no measured disturbance level exceeds the disturbance limit;
–non - compliance is deemed to occur if any measured disturbance level exceeds the disturbance limit.
If Ulab is greater than Ucispr of Table 1, then:
–compliance is deemed to occur if no measured disturbance level, increased by (Ulab − Ucispr), exceeds the
disturbance limit;
–non - compliance is deemed to occur if any measured disturbance level, increased by (Ulab − Ucispr),
exceeds the disturbance limit.

Based on CISPR 16-4-2: 2011, measurement uncertainty of conducted disturbance at mains port using AMN at
Bay Area Compliance Laboratories Corp. (Dongguan) is 3.46 dB (150 kHz to 30 MHz).

                                         Table 1 – Values of Ucispr

                                Measurement                                            Ucispr
Conducted disturbance at mains port using AMN (150 kHz to 30 MHz)                      3.4 dB


EUT Setup




The setup of EUT is according with per ANSI C63.4-2003 measurement procedure. The specification used
was with the FCC Part 15.107 Class B limits.
FCC Part15B, Class B                                                                            Page 8 of 19


Bay Area Compliance Laboratories Corp. (Dongguan)                        Report No.: R2DG130314004-00A

The adapter was connected to a 120 VAC/60 Hz power source.


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 adapter was connected to the outlet of the first LISN and the other
support equipments were connected to the outlet of 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.


Corrected Amplitude & Margin Calculation
The basic equation is as follows:

VC = VR + AC + VDF
Cf = AC + VDF

Herein,
VC (cord. Reading): corrected voltage amplitude
VR: reading voltage amplitude
Ac: attenuation caused by cable loss
VDF: voltage division factor of AMN
Cf: Correction Factor


The “Margin” column of the following data tables indicates the degree of compliance within the
applicable limit. For example, a margin of 7dB means the emission is 7dB below the maximum limit. The
equation for margin calculation is as follows:

        Margin = Limit – Corrected Amplitude

FCC §15.109 - RADIATED EMISSIONS
Measurement Uncertainty
Compliance or non- compliance with a disturbance limit shall be determined in the following manner:

If Ulab is less than or equal to Ucispr of Table 2, then:
–compliance is deemed to occur if no measured disturbance level exceeds the disturbance limit;
–non - compliance is deemed to occur if any measured disturbance level exceeds the disturbance limit.
If Ulab is greater than Ucispr of Table 1, then:
–compliance is deemed to occur if no measured disturbance level, increased by (Ulab − Ucispr), exceeds the
disturbance limit;
–non - compliance is deemed to occur if any measured disturbance level, increased by (Ulab − Ucispr),
exceeds the disturbance limit.

Based on CISPR 16-4-2: 2011, measurement uncertainty of radiated emission at a distance of 3m at Bay
Area Compliance Laboratories Corp. (Dongguan) is:
30M~200MHz: 5.0 dB
200M~1GHz: 6.2 dB
1G~6GHz: 4.45 dB
6G~18GHz: 5.23 dB

Above 1 G:




The radiated emission tests were performed in the 3 meters chamber test site, using the setup accordance
with the ANSI C63.4-2003. The specification used was the FCC Part 15.109, Class B limits.

The external I/O cables were draped along the test table and formed a bundle 30 to 40 cm long in the
middle.

The adapter connected to a 120 VAC/60 Hz power source.


EMI Test Receiver Setup
According to FCC 15.33 requirements, the system was measured from 30 MHz to 6 GHz.

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

           Frequency Range            RBW        Video B/W       Detector
          30 MHz – 1000 MHz          120 kHz     300 kHz          QP
          Above 1 GHz                 1MHz       3 MHz            Peak
          Above 1 GHz                 1MHz       10 Hz            Ave


Test Procedure
For the radiated emissions test, the adapter was connected to the first AC floor outlet and the other support
equipments were connected to the second AC floor outlet.
Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all
installation combinations.
The data was recorded in Quasi-peak detection mode for 30 MHz to 1 GHz, Peak and average detection
mode above 1 GHz.

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

        Corrected Amplitude = Meter Reading + Antenna Loss + 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
