Peripherals 0.8 meter Ground Plane Radiated emission measurements were performed from 30MHz to tenth harmonic or 40GHz. The EUT for testing is arranged on a wooden turntable. If some peripherals apply to the EUT, the peripherals will be connected to EUT and the whole system. During the test, all cables were arranged to produce worst-case emissions. The signal is maximized through rotation. The height of antenna and polarization is changing constantly for exploring for maximum signal level. The height of antenna can be up to 4 meters and down to 1 meter. RF Test Receiver FCC ID. : MQ4SDW3100 Report No.: TS08120011-EME Page 20 of 29 The measurement for radiated emission will be done at the distance of three meters unless the signal level is too low to measure at that distance. In the case of the reading under noise floor, a pre-amplifier is used and/or the test is conducted at a closer distance. And then all readings are extrapolated back to the equivalent three meter reading using inverse scaling with distance. 6.3 Emission limits The spurious Emission shall test through the 10th harmonic. In addition, radiated emissions which fall in the restricted bands, as defined in 15.205(a), must also comply with the radiated emission limits specified in 15.209(a). Frequency

8.2 Procedure of test setup & limitation The additional provisions mean the device must be designed to ensure that the 20dB bandwidth of the emission or whatever bandwidth may otherwise be specified in the specific rule section under which the equipment operates, is contained within the frequency band designated in the rule section under which the equipment is operated. This requirement per FCC 15.215 (c) was measured from the antenna port of the EUT using a 50ohm spectrum analyzer with the resolution bandwidth set at 300kHz (approximately 1%
of the emission bandwidth), the video bandwidth set at 1MHz (VBW > RBW). FCC ID. : MQ4SDW3100 Report No.: TS08120011-EME Page 29 of 29 8.3 Measured data of Power Spectrum Density test results Operating Frequency: 5240 MHz Operating Frequency: 5260 MHz
