Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: R2DG130813005-00A 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 FCC Part15B Page 7 of 18

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: R2DG130813005-00A 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. 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 Part15B Page 8 of 18
