Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190111831-00 FCC §15.235(a) & 15.235 (b)&15.209 - RADIATED EMISSIONS AND BAND EDGES Applicable Standard FCC 15.235(a) The field strength of any emission within this band shall not exceed 10,000 microvolts/meter at 3 meters. The emission limit in this paragraph is based on measurement instrumentation employing an average detector. The provisions in §15.35 for limiting peak emissions apply. FCC 15.235(b) The field strength of any emissions appearing between the band edges and up to 10 kHz above and below the band edges shall be attenuated at least 26 dB below the level of the unmodulated carrier or to the general limits in §15.209, whichever permits the higher emission levels. The field strength of any emissions removed by more than 10 kHz from the band edges shall not exceed the general radiated emission limits in §15.209. All signals exceeding 20 microvolts/meter at 3 meters shall be reported in the application for certification. 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 5.81 dB for 30MHz-1GHz.and 4.88 dB for above 1GHz, and it will not be taken into consideration for the test data recorded in the report. EUT Setup The radiated emission tests were performed in the 3 meters, using the setup accordance with the ANSI C63.10-2013. The specification used was the FCC Part 15.235(a) & 15.235 (b) &15.209 limits. FCC Part 15.235 Page 8 of 14

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190111831-00 EMI Test Receiver Setup The system was investigated from 30 MHz to 1000 MHz. 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 30MHz – 1000 MHz 100 kHz 300 kHz 120 kHz QP Test Procedure Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all installation combinations. All radiated emission data was recorded in the Quasi-peak detection mode from 30MHz to 1GHz, Peak and average detection mode for fundamental test. 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 7 dB means the emission is 7 dB below the maximum limit. The equation for margin calculation is as follows: Margin = Limit - Corrected Amplitude Test Results Summary According to the data in the following table, the EUT complied with the FCC Part 15.235(a) & 15.235 (b) &15.209 FCC Part 15.235 Page 9 of 14

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190111831-00 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 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.
