Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ130221003-00 FCC §15.107 – AC LINE CONDUCTED EMISSIONS Applicable Standard According to FCC §15.107 Measurement Uncertainty All measurements involve certain levels of uncertainties, especially in field of EMC. The factors contributing to uncertainties are spectrum analyzer, cable loss, and LISN. Based on CISPR 16-4-2, The Treatment of Uncertainty in EMC Measurements, the best estimate of the uncertainty of any conducted emissions measurement at Bay Area Compliance Laboratories Corp. (Shenzhen) is 2.4 dB(k=2, 95% level of confidence), and the uncertainty will not be taken into consideration for the test data recorded in the report. EUT Setup The measurement procedure of EUT setup is according with per ANSI C63.4-2003. The related limit was specified in FCC Part 15.107 Class B. The spacing between the peripherals was 10 cm. The adapter was connected to a 120 VAC/60 Hz power source. FCC Part 15 B, Class B Page 7 of 18
