Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RSHA190625006-00A Corrected Factor & Over Limit Calculation The Corrected Factor is calculated by adding LISN VDF (Voltage Division Factor), Cable Loss and Transient Limiter Attenuation. The basic equation is as follows: Corrected Factor (dB) = LISN VDF (dB) + Cable Loss (dB) + Transient Limiter Attenuation (dB) The “Over Limit” 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 above the limit. The equation for margin calculation is as follows: Over Limit (dB) = Read level (dBμV) + Factor (dB) - Limit (dBμV) Test Results Summary According to the recorded data in following table, the EUT complied with the FCC Part 15.207. Test Data Environmental Conditions Temperature: 25.0℃ Relative Humidity: 48 % ATM Pressure: 101.2 kPa The testing was performed by Kyle xu on 2019-07-02. Test Result: Compliant.

Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RSHA190625006-00A 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 Part 15.209 &15.205 & 15.249.

Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RSHA190625006-00A 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. Test Data Environmental Conditions Temperature: 24.4C Relative Humidity: 50% ATM Pressure: 101.3kPa The testing was performed by Kyle xu on 2019-06-27. Test Result: Compliant.
