FCC ID: C3K1855 IC ID: 3048A-1855 9.7 Conducted Band Edge Emissions Test Requirement: FCC CFR 47 Rule Part 15.247 (d) ISED RSS-247 [5.5] Test Method: Measurements were performed according to the procedure defined in KDB 558074 - Guidance for Performing Compliance Measurements on Digital Transmission Systems (DTS) Operating Under §15.247 V05 and ANSI C63.10 2013. Spectrum analyzer settings: Span = wide enough to capture the peak level of the emission operating on the channel closest to the band edge, as well as any modulation products which fall outside of the authorized band of operation RBW = 100 kHz VBW = 300 kHz Sweep = auto couple Detector function = Peak Trace = Max Hold The trace was allowed to stabilize. The marker was set on the emission at the band edge, or on the highest modulation product outside of the band, if this level is greater than that at the band edge. The delta marker function was set and the marker-to-peak function moved to the peak of the in-band emission. Limits: All spurious emissions at least 30dBc since average power measurements are reported. Test Result: Pass.

FCC ID: C3K1855 IC ID: 3048A-1855 9.8 Radiated Spurious and Band Edge Emissions Test Requirement: FCC CFR 47 Rule Part 15.247 (d) ISED RSS-247 [5.5] and RSS GEN [8.9] Test Method: Measurements were performed according to the procedure defined in KDB 558074 - Guidance for Performing Compliance Measurements on Digital Transmission Systems (DTS) Operating Under §15.247 V05 and ANSI C63.10: 2013. Radiated spurious measurements are made from 9kHz/30MHz to the 10th harmonic of the fundamental frequency of the transmitter. Measurements below 30MHz were not performed since the radio circuitry of the EUT does not contain clocks below 30MHz.The limit for radiated spurious emissions is per 15.209 and RSS-247 [5.5]. Additionally, emissions found in the restricted bands as listed in 15.205 were tested for compliance per limits in 15.209 and RSS- Gen. The EUT was tested near the low, middle and high channels of operation in each sub band. Guidelines in ANSI C63.10:2013 were followed with respect to maximizing the emissions. A pre-amp and a high pass filter were required for this test to provide the measuring system with sufficient sensitivity. The peak reading of the emission, after being corrected by the antenna factor, cable loss, pre-amp gain, etc., is the peak field strength. Both horizontal and vertical antenna polarizations were investigated. Worst-case maximized data for both polarizations is shown in this test report. All tests were performed in MIMO transmission mode to measure the worst case for both antennas Report#: R-TR516-FCCISED-WLAN-3 Issued: July 15, 2019 Page 165 of 207 Microsoft EMC Laboratory
