Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG150730005-00 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 Compliance or non- compliance with a disturbance limit shall be determined in the following manner： If Ulab is less than or equal to Ucispr of Table 1, then: –compliance is deemed to occur if no measured disturbance level exceeds the disturbance limit; –non - compliance is deemed to occur if any measured disturbance level exceeds the disturbance limit. If Ulab is greater than Ucispr of Table 1, then: –compliance is deemed to occur if no measured disturbance level, increased by (Ulab − Ucispr), exceeds the disturbance limit; –non - compliance is deemed to occur if any measured disturbance level, increased by (Ulab − Ucispr), exceeds the disturbance limit. Based on CISPR 16-4-2: 2011, measurement uncertainty of radiated emission at a distance of 3m at Bay Area Compliance Laboratories Corp. (Dongguan) is: 30M~200MHz: 5.0 dB 200M~1GHz: 6.2 dB 1G~6GHz: 4.45 dB 6G~18GHz: 5.23 dB FCC Part 15.249 Page 7 of 17

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG150730005-00 Test Equipment Setup The system was investigated from 30 MHz to 25 GHz. During the radiated emission test, the EMI test receiver & Spectrum Analyzer Setup were set with the following configurations: Frequency Range RBW Video B/W IF B/W Detector 30 MHz – 1000 MHz 120 kHz 300 kHz 120 kHz QP 1MHz 3 MHz / PK Above 1 GHz 1MHz 10 Hz / Ave. Test Procedure Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all installation combinations. All data was recorded in the Quasi-peak detection mode from 30MHz to 1GHz, Peak and average detection mode above 1 GHz. 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 9 of 17

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG150730005-00 FCC §15.215(c) – 20 dB BANDWIDTH TESTING 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 on the test table without connection to measurement instrument. Turn on the EUT. 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 were attenuated 20 dB from the reference level. Record the frequency difference as the emission bandwidth. 4. Repeat above procedures until all frequencies measured were complete.
