Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RSHA190617002-00A FCC §15.205, §15.209, §15.231 (b) - RADIATED EMISSIONS Applicable Standard FCC §15.205, §15.209, §15.231 (b) According to FCC §15.231(b), the field strength of emissions from intentional radiators operated under this section shall not exceed the following: Field strength of fundamental Field strength of spurious Fundamental frequency (MHz) (microvolts/meter) emission (microvolts/meter) 40.66-40.70 2250 225 70-130 1250 125 130-174 1250 to 3750 ** 125 to 375 ** 174-260 3750 375 260-470 3750 to 12500 ** 375 to 1250** Above 470 12500 1250 Note: ** means Linear interpolations (1) The above field strength limits are specified at a distance of 3 meters. The tighter limits apply at the band edges. (2) Intentional radiators operating under the provisions of this section shall demonstrate compliance with the limits on the field strength of emissions, as shown in the above table, based on the average value of the measured emissions. As an alternative, compliance with the limits in the above table may be based on the use of measurement instrumentation with a CISPR quasi-peak detector. The specific method of measurement employed shall be specified in the application for equipment authorization. If average emission measurements are employed, the provisions in §15.35 for averaging pulsed emissions and for limiting peak emissions apply. Further, compliance with the provisions of §15.205 shall be demonstrated using the measurement instrumentation specified in that section. (3) The limits on the field strength of the spurious emissions in the above table are based on the fundamental frequency of the intentional radiator. Spurious emissions shall be attenuated to the average (or, alternatively, CISPR quasi-peak) limits shown in this table or to the general limits shown in §15.209, whichever limit permits a higher field strength.

Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RSHA190617002-00A EUT Setup Below 1GHz: Above 1 GHz: The radiated emission tests were performed in the 3 meters test site, using the setup accordance with the ANSI C63.10 - 2013. The specification used was the FCC 15 § 15.209, 15.205 and 15.231. FCC Part 15.231 Page 11 of 20

Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RSHA190617002-00A EMI Test Receiver Setup The system was investigated from 30 MHz to 5 GHz. During the radiated emission test, the EMI test Receiver was set with the following configurations: Frequency Range RBW Video B/W IF B/W Detector 30 MHz – 1000 MHz 100 kHz 300 kHz / PK 1000MHz – 5000MHz 1MHz 3MHz / PK Test Procedure Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all installation combinations. 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 (dBμV /m) = Meter Reading (dBμV) + Antenna Factor (dB/m) + Cable Loss (dB) - Amplifier Gain (dB) 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 (dB) = Limit (dBμV/m) – Corrected Amplitude (dBμV /m) Test Results Summary According to the data in the following table, the EUT complied with the FCC §15.205, §15.209, §15.231 (b).
