(Shenzhen) REQUIREMENTS AND TEST PROCEDURES AC Line Conducted Emissions Applicable Standard FCC§15.207 EUT Setup Report No.: 2401A64515E-RF-00 The setup of EUT is according with per ANSI C63.10-2013 measurement procedure. The specification used was with the FCC Part 15.207 limits. The spacing between the peripherals was 10 cm. EMI Test Receiver Setup The EMI test receiver was set to investigate the spectrum from 150 kHz to 30 MHz. During the conducted emission test, the EMI test receiver was set with the following configurations: Frequency Range 150 kHz 30 MHz IF B/W 9 kHz TR-EM-RF003 Page 10 of 59 Version 4.0 Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: 2401A64515E-RF-00 Test Procedure Maximizing procedure was performed on the six (6) highest emissions of the EUT. All final data was recorded in the Quasi-peak and average detection mode. Factor & Over Limit Calculation The factor is calculated by adding LISN VDF (Voltage Division Factor) and Cable Loss. The basic equation is as follows: Factor = LISN VDF + Cable Loss The "Over limit" column of the following data tables indicates the degree of compliance with the applicable limit. For example, an Over limit of -7 dB means the emission is 7 dB below the limit. The equation for calculation is as follows: Over Limit = Level Limit Level = Read Level + Factor Note: The term "cable loss" refers to the combination of a cable and a 10dB transient limiter (attenuator).

(Shenzhen) Above 1GHz: Report No.: 2401A64515E-RF-00 The radiated emission tests were performed in the 3meters test site, using the setup accordance with the ANSI C63.10-2013. The specification used was the FCC 15.205, FCC 15.209, FCC 15.247 limits. The external I/O cables were draped along the test table and formed a bundle 30 to 40 cm long in the middle. EMI Test Receiver & Spectrum Analyzer Setup The system was investigated from 9 kHz to 25 GHz. During the radiated emission test, the EMI test receiver & Spectrum Analyzer Setup were set with the following configurations: 9 kHz-1GHz: Frequency Range 9 kHz 150 kHz 150 kHz 30 MHz 30 MHz 1000 MHz 1-25GHz: Pre-scan RBW / 300 Hz / 10 kHz / 100 kHz Video B/W / 1 kHz / 30 kHz / 300 kHz IF B/W 200 Hz / 9 kHz / 120 kHz / Measurement QP PK QP PK QP PK Detector QP Peak QP Peak QP Peak Measurement PK AV Duty cycle Any >98% <98% RBW 1MHz 1MHz 1MHz Video B/W 3 MHz 1 kHz 1/Ton Detector Peak Peak Peak TR-EM-RF003 Page 13 of 59 Version 4.0 Bay Area Compliance Laboratories Corp.

Test Procedure Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all installation combinations. All final data was recorded in Quasi-peak detection mode except for the frequency bands 990 kHz, 110 490 kHz and above 1000 MHz, average detection modes for frequency bands 990 kHz and 110490 kHz, peak and average detection modes for frequencies above 1 GHz. For 9 kHz-30MHz, the report shall list the six emissions with the smallest margin relative to the limit, for each of the three antenna orientations (parallel, perpendicular, and ground-parallel) unless the margin is greater than 20 dB. All emissions under the average limit and under the noise floor have not recorded in the report. Factor & Over Limit/Margin Calculation The Factor is calculated by adding the Antenna Factor and Cable Loss, and subtracting the Amplifier Gain. The basic equation is as follows: Factor = Antenna Factor + Cable Loss - Amplifier Gain The "Over Limit/Margin" column of the following data tables indicates the degree of compliance with the applicable limit. For example, an Over Limit/margin of -7dB means the emission is 7dB below the limit. The equation for calculation is as follows: Over Limit/Margin = Level / Corrected Amplitude Limit Level / Corrected Amplitude = Read Level + Factor TR-EM-RF003 Page 14 of 59 Version 4.0 Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: 2401A64515E-RF-00 6 dB Emission Bandwidth Standard Applicable According to FCC §15.247(a) (2) Systems using digital modulation techniques may operate in the 902928 MHz, 24002483.5 MHz, and 57255850 MHz bands. The minimum 6 dB bandwidth shall be at least 500 kHz. Test Procedure Test Method: ANSI C63.10-2013 Clause 11.8.1 & Clause 6.9.3 a. Set RBW = 100 kHz. b. Set the VBW [3×RBW]. c. Detector = peak. d. Trace mode = max hold. e. Sweep = auto couple. f. Allow the trace to stabilize. g. Measure the maximum width of the emission that is constrained by the frequencies associated with the two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 dB relative to the maximum level measured in the fundamental emission. The occupied bandwidth is the frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers are each equal to 0.5% of the total mean power of the given emission. Procedure as below a. The instrument center frequency is set to the nominal EUT channel center frequency. The frequency span for the spectrum analyzer shall be between 1.5 times and 5.0 times the OBW. b. The nominal IF filter bandwidth (3 dB RBW) shall be in the range of 1% to 5% of the OBW, and VBW shall be approximately three times the RBW, unless otherwise specified by the applicable requirement. c. Set the reference level of the instrument as required, keeping the signal from exceeding the maximum input mixer level for linear operation. In general, the peak of the spectral envelope shall be more than [10 log (OBW/RBW)] below the reference level. d. Step a) through step c) might require iteration to adjust within the specified range. e. Video averaging is not permitted. Where practical, a sample detection and single sweep mode shall be used. Otherwise, peak detection and max hold mode (until the trace stabilizes) shall be used. f. Use the 99% power bandwidth function of the instrument (if available) and report the measured bandwidth. g. If the instrument does not have a 99% power bandwidth function, then the trace data points are recovered and directly summed in linear power terms. The recovered amplitude data points, beginning at the lowest frequency, are placed in a running sum until 0.5% of the total is reached; that frequency is recorded as the lower frequency. The process is repeated until 99.5% of the total is reached; that frequency is recorded as the upper frequency. The 99% power bandwidth is the difference between these two frequencies. h. The occupied bandwidth shall be reported by providing plot(s) of the measuring instrument display; the plot axes and the scale units per division shall be clearly labeled. Tabular data may be reported in addition to the plot(s). TR-EM-RF003 EUT Spectrum Analyzer Attenuator Page 15 of 59 Version 4.0 Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: 2401A64515E-RF-00 Peak Output Power Measurement Applicable Standard According to FCC §15.247(b) (3), for systems using digital modulation in the 902-928 MHz, 2400-2483.5 MHz, and 5725-5850 MHz bands: 1 Watt.

Power must be summed across all antennas and antenna elements. The average must not include any time intervals during which the transmitter is off or is transmitting at a reduced power level. If multiple modes of operation are possible (e.g., alternative modulation methods), the maximum conducted output power is the highest total transmit power occurring in any mode. Test Procedure Test Method: ANSI C63.10-2013 Clause 11.9.1.1 1. Place the EUT on a bench and set it in transmitting mode. 2. Remove the antenna from the EUT and then connect a low loss RF cable from the antenna port to one test equipment. 3. Add a correction factor to the display. 4. Set the RBW DTS bandwidth. 5.

According to KDB 447498 D01 General RF Exposure Guidance v06. The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [f(GHz)] 3.0 for 1-g SAR and 7.5 for 10-g extremity SAR, where 1. f(GHz) is the RF channel transmit frequency in GHz. 2. Power and distance are rounded to the nearest mW and mm before calculation. 3. The result is rounded to one decimal place for comparison. 4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test Exclusion.
