(Dongguan) attests that all calibrations have been performed, traceable to National Primary Standards and International System of Units (SI). Test Procedure During the conducted emission test, the adapter or POE was connected to the outlet of the LISN. Maximizing procedure was performed on the six (6) highest emissions of the EUT. All data was recorded in the Quasi-peak and average detection mode. According FCC publication number 174176,for a device with a permanent antenna operating at or below 30 MHz, the measurements done with a suitable dummy load, in lieu of the permanent antenna under the following conditions: (1) perform the AC line conducted tests with the permanent antenna to determine compliance with the Section 15.207 limits outside the transmitter's fundamental emission band; (2) retest with a dummy load in lieu of the permanent antenna to determine compliance with the Section 15.207 limits within the transmitter's fundamental emission band. Corrected Amplitude & Margin Calculation The basic equation is as follows: VC = VR + AC + VDF Herein, VC: corrected voltage amplitude VR: reading voltage amplitude Ac: attenuation caused by cable loss VDF: voltage division factor of AMN or ISN The “Margin” column of the following data tables indicates the degree of compliance within 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 Page 10 of 29

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RXM190515053-00A EUT Setup The radiated emission tests were performed in the 10-meter chamber test site, using the setup accordance with the ANSI C63.10-2013. The specification used was the FCC Part Subpart C limits. The spacing between the peripherals was 10 cm. EMI Test Receiver Setup The system was investigated from 9 kHz to 1 GHz. During the radiated emission test, the EMI test Receiver was set with the following configurations: Frequency Range RBW Video B/W Measurement 9 kHz – 150 kHz 200 Hz 1 kHz QP/Average 150 kHz – 30 MHz 9 kHz 30 kHz QP/Average 30 MHz – 1000 MHz 120 kHz 300 kHz QP The emission limits shown in the above table are based on measurements employing a CISPR quasi-peak detector except for the frequency bands 9-90 kHz, 110-490 kHz and above 1000 MHz. Radiated emission limits in these three bands are based on measurements employing an average detector. If the maximized peak measured value complies with the limit, then it is unnecessary to perform an QP/Average measurement Page 17 of 29

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RXM190515053-00A Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Loss, and subtracting the Amplifier Gain from the Amplitude reading. The basic equation is as follows: Corr. Ampl. = 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 - Corr. Ampl.

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RXM190515053-00A FCC§15.225(e) - FREQUENCY STABILITY Applicable Standard The frequency tolerance of the carrier signal shall be maintained within ±0.01% of the operating frequency over a temperature variation of −20 degrees to +50 degrees C at normal supply voltage, and for a variation in the primary supply voltage from 85% to 115% of the rated supply voltage at a temperature of 20 degrees C. For battery operated equipment, the equipment tests shall be performed using a new battery. Test Procedure Frequency Stability vs. Temperature: The adapter under test was connected to an external power. The EUT was placed inside the temperature chamber. After the temperature stabilized for approximately 20 minutes, the frequency output was recorded from the Spectrum Analyzer. Frequency Stability vs. Voltage: An external variable power supply Source connected to the EUT or EUT adapter. Test the frequency output in the extremity voltage.

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RXM190515053-00A FCC §15.215(c) – 20 dB EMISSION BANDWIDTH Applicable Standard Per FCC §15.215 (c) 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. The requirement to contain the designated bandwidth of the emission within the specified frequency band includes the effects from frequency sweeping, frequency hopping and other modulation techniques that may be employed as well as the frequency stability of the transmitter over expected variations in temperature and supply voltage. If a frequency stability is not specified in the regulations, it is recommended that the fundamental emission be kept within at least the central 80% of the permitted band in order to minimize the possibility of out-of - band operation. Test Procedure Measure the frequency difference of two frequencies that were attenuated 20 dB from the reference level. Record the frequency difference as the emission bandwidth.
