Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ 8080183100 FCC§15.205, §15.209, §15.227(a), §15.227 (b)—FIELD STRENGTH AND RESTRICTED BAND EMISSIONS Applicable Standard According to FCC §15.227 (a), the field strength if any emission within this band shall not exceed 10,000 microvolts/meter at 3 meters. (b) The field strength of any emissions which appear outside of this band shall not exceed the general radiated emission limits in §15,209. 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—4, The Treatment of Uncertainty in EMC Measurements, the best estimate of the uncertainty of a radiation emissions measurement at Bay Area ComplianceLaboratories Corp. (Shenzhen} is 4.0 dB.(k=2, 95% level of confidence},and the uncertainty will not be taken into consideration for all the test data recorded in the report. EUT Setup Ant.

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ180801831-00 EMI Test Receiver Setup The system was investigated from 9 kHz to 1000 MHz. Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Loss and Cable Loss, and subtracting the Amplifier Gain from the Meter reading. The basic equation is as follows: Corrected Amplitude = Meter Reading + Correction Factor Correction Factor = Antenna Loss + 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 Data Environmental Conditions Temperature: 26 ℃ Relative Humidity: 55 % ATM Pressure: 101.0 kPa Testing was performed by Bibo Zhang on 2018-08-09.

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ180801831-00 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.
