Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ150828004-00 FCC§15.205, §15.209 & §15.249 - RADIATED EMISSIONS Applicable Standard As per FCC§15.249 (a), except as provided in paragraph (b) of this section, the field strength of emissions from intentional radiators operated within these frequency bands shall comply with the following: Fundamental Field strength of fundamental Field strength of harmonics frequency (millivolts/meter) (microvolts/meter) 902–928 MHz 50 500 2400–2483.5 MHz 50 500 5725–5875 MHz 50 500 24.0–24.25 GHz 250 2500 As per FCC§15.249 (c), Field strength limits are specified at a distance of 3 meters. (d) Emissions radiated outside of the specified frequency bands, except for harmonics, shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission limits in §15.209, whichever is the lesser attenuation. Measurement Uncertainty All measurements involve certain levels of uncertainties, especially in field of EMC. The factors contributing to uncertainties are spectrum analyzer, cable loss, antenna factor calibration, antenna directivity, antenna factor variation with height, antenna phase center variation, antenna factor frequency interpolation, measurement distance variation, site imperfections, mismatch (average), and system repeatability. Based on CISPR 16-4-2:2011, the expended combined standard uncertainty of radiation emissions at Bay Area Compliance Laboratories Corp. (Shenzhen) is 5.91 dB for 30MHz-1GHz, 4.92 dB for above 1GHz, and it will not be taken into consideration for the test data recorded in the report Test Equipment Setup The spectrum analyzer or receiver is set as: Below 1000MHz: RBW = 100 kHz / VBW = 300 kHz / Sweep = Auto Above 1000MHz: Peak: RBW = 1MHz / VBW = 1MHz / Sweep = Auto Average: RBW = 1MHz / VBW = 10Hz / Sweep = Auto FCC Part 15.249 Page 9 of 19

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ150828004-00 EUT Setup The radiated emission and out of band emission tests were performed in the 3 meters chamber test site, using the setup accordance with the ANSI C63.10-2013. The specification used was the FCC 15.209/15.205 and FCC 15.249 limits. Test Procedure Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all installation combinations. The EUT is set 3 meter away from the testing antenna, which is varied from 1-4 mete, and the EUT is placed on a turntable, which is 0.8 meter above ground plane, the table shall be rotated for 360 degrees to find out the highest emission. The receiving antenna should be changed the polarization both of horizontal and vertical. Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Loss, and subtracting the Amplifier Gain from the Meter Reading. The basic equation is as follows: Corrected Amplitude = Meter Reading + Antenna Factor + Cable Loss - Amplifier Gain The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit. For example, a margin of 7dB means the emission is 7dB below the limit. The equation for margin calculation is as follows: Margin = Limit – Corrected Amplitude FCC Part 15.249 Page 10 of 19

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ150828004-00 FCC§15.215(c) - 20dB EMISSION BANDWIDTH Applicable Standard Intentional radiators operating under the alternative provisions to the general emission limits, as contained in § 15.217 through 15.257 and in Subpart E of this part, must be designed to ensure that the 20 dB 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. Test Procedure 1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. 2. Position the EUT without connection to measurement instrument. Turn on the EUT and connect it to measurement instrument. Then set it to any one convenient frequency within its operating range. Set a reference level on the measuring instrument equal to the highest peak value. 3. Measure the frequency difference of two frequencies that indicated 20dB bandwidth. 4. Repeat above procedures until all frequencies measured were complete.
