Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG190529001-00B 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. EUT Setup Below 1 GHz: Page 9 of 19

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG190529001-00B Above 1 GHz: The radiated emission below 1GHz tests were performed in the 3 meters chamber test site A, above 1GHz tests were performed in the 3 meters chamber test site B, using the setup accordance with the ANSI C63.10-2013. The specification used was the FCC 15.209, and FCC 15.249 limits. 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 Measurement 30 MHz – 1000 MHz 120 kHz 300 kHz 120 kHz QP 1MHz 3 MHz / PK Above 1 GHz 1MHz 10 Hz / AV If the maximized peak measured value complies with under the QP/Average limit more than 6dB, then it is unnecessary to perform an QP/Average measurement. Page 10 of 19

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG190529001-00B 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 30 MHz 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 Test Equipment List and Details Serial Calibration Calibration Manufacturer Description Model Number Date Due Date R&S EMI Test Receiver ESCI 100224 2018-12-10 2019-12-10 Farad Test Software EZ-EMC V1.1.4.2 N/A N/A Sunol Sciences Antenna JB3 A060611-1 2017-11-10 2020-11-10 Unknown Coaxial Cable C-NJNJ-50 C-0400-01 2018-09-05 2019-09-05 Unknown Coaxial Cable C-NJNJ-50 C-0075-01 2018-09-05 2019-09-05 Unknown Coaxial Cable C-NJNJ-50 C-1400-01 2018-09-05 2019-09-05 HP Amplifier 8447D 2727A05902 2018-09-05 2019-09-05 Agilent Spectrum Analyzer E4440A SG43360054 2019-01-04 2020-01-04 ETS-Lindgren Horn Antenna 3115 000 527 35 2018-10-12 2021-10-12 AFS42-00101800-25- MITEQ Amplifier 2001271 2018-09-05 2019-09-05 S-42 Unknown Coaxial Cable C-SJSJ-50 C-0800-01 2018-09-05 2019-09-05 Unknown Coaxial Cable C-2.4J2.4J-50 C-0700-02 2018-06-27 2019-06-27 Ducommun 1007726-01 Horn Antenna ARH-4223-02 2016-11-18 2019-11-18 Technolagies 1304 Quinstar Amplifier QLW-18405536-JO 15964001001 2018-06-27 2019-06-27 E-Microwave Band-stop Filters OBSF-2400-2483.5-S OE01601525 2018-06-16 2019-06-16 Micro-tronics High Pass Filter HPM50111 S/N-G217 2018-06-16 2019-06-16 * Statement of Traceability: Bay Area Compliance Laboratories Corp.

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG190529001-00B 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. Measure the frequency difference of two frequencies that were attenuated 20 dB from the reference level. Record the frequency difference as the emission bandwidth. 3. Repeat above procedures until all frequencies measured were complete.
