9 FCC ID: YLFSE21WL 6 RADIATED SPURIOUS EMISSION The EUT antenna port was fitted with its integral/internal chip antenna. Radiated emissions were measured in a Semi-Anechoic Chamber. All emissions generated that fall in the restricted bands per FCC Part were examined. 6.1 Requirements: All emissions that fall in the restricted bands defined in FCC Part shall not exceed the maximum field strength listed in FCC Part 15.29(a) Report Number: F2LQ7176-1E Page 9 of 39 Issue Date: Aug. 25, 215

10 FCC ID: YLFSE21WL 6.2 Radiated Spurious Emission Test Data Test Date(s): June 3, 215 Test Engineer: J. Knepper Standards: CFR 47 Part (d); Part / KDB55874 Air Temperature: 22.4ºC Relative Humidity: 46% Notes: Plots are peak, max hold prescan data included only to determine what frequencies to investigate and measure. The EUT was initially placed in a semi-anechoic chamber, and rotated in all three orthogonal positions to maximize the emissions. The orthogonal position that showed the highest emissions was used. Characterization measurements were then performed to determine at which frequencies significant emissions occurred. These graphs are shown below. The equipment was fully exercised with all cabling attached to the EUT and was positioned in a semi-anechoic chamber for maximum emissions. While the equipment was energized, the receiving antenna was scanned from 1. meter to 4. meters in both vertical and horizontal polarities while the turntable was adjusted 36 degrees to determine the maximum field strength. The tables of measured results can be found below. Some of the frequencies did not change with the EUT on or off. At those frequencies, the test distance was shortened to 1 meter and still no emissions from the EUT were visible or over the ambient or limit. In the following plots, emissions to be found by the EUT were measured and listed in tables. The plots are for reference only and the limit lines are not actual limit lines but merely a guide. The 2 MHz 82.11n bandwidth was found to be the worst case emissions Report Number: F2LQ7176-1E Page 1 of 39 Issue Date: Aug. 25, 215

34 FCC ID: YLFSE21WL 7 CONDUCTED EMISSIONS 7.1 Requirements In accordance with FCC CFR 47 Part 15.27(a), Except as shown in paragraphs (b) and (c) of this section, for an intentional radiator that is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies, within the band 15 khz to 3 MHz, shall not exceed the limits in the following table, as measured using a 5 μh/5 ohms line impedance stabilization network (LISN). Compliance with the provisions of this paragraph shall be based on the measurement of the radio frequency voltage between each power line and ground at the power terminal. The lower limit applies at the boundary between the frequency ranges. Conducted Limit (dbμv) Frequency of Emission (MHz) Quasi-peak to 56* 56 to 46* Average *Decreases with the logarithm of the frequency. 7.2 Procedure The EUT was placed on a 1. x 1.5 meter non-conductive table,.8 meter above a horizontal ground plane and.4 meter from a vertical ground plane. Power was provided to the EUT through a LISN bonded to a 3 x 2 meter ground plane. The LISN and peripherals were supplied power through a filtered AC power source. The output of the LISN was connected to the input of the receiver via a transient limiter, and emissions in the range 15 khz to 3 MHz were measured. The measurements were recorded using the quasi-peak and average detectors as directed by the standard, and the resolution bandwidth during testing was 9 khz. The raw measurements were corrected to allow for attenuation from the LISN, transient limiter and cables Report Number: F2LQ7176-1E Page 34 of 39 Issue Date: Aug. 25, 215
