TEST METHODOLOGY The tests documented in this report were performed in accordance with ANSI C63.10-2013, FCC CFR PART 15C 15.207. 2.1 EUT Configuration The EUT configuration for testing is installed on RF field strength measurement to meet the Commissions requirement and operating in a manner that intends to maximize its emission characteristics in a continuous normal application. 2.2 EUT Exercise According to its specifications, the EUT must comply with the requirements of the Section 15.207 under the FCC Rules Part 15 Subpart C. 2.3 General Test Procedures 2.3.1 Conducted Emissions The EUT is placed on the turntable, which is 0.8 m above ground plane. According to the requirements in Section 6.2.1 of ANSI C63.10-2013 Conducted emissions from the EUT measured in the frequency range between 0.15 MHz and 30MHz using Quasi-peak and average detector modes. 2.3.2 Radiated Emissions The EUT is placed on a turn table, which is 0.8 m above ground plane below 1GHz and 1.5 m above ground plane above 1GHz. The turntable shall rotate 360 degrees to determine the position of maximum emission level. EUT is set 3m away from the receiving antenna, which varied from 1m to 4m to find out the highest emission. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. In order to find out the maximum emissions, exploratory radiated emission measurements were made according to the requirements in Section 6.3 of ANSI C63.10-2013 Shenzhen LCS Compliance Testing Laboratory Ltd.

POWER LINE CONDUCTED MEASUREMENT 6.1. Block Diagram of Test Setup Report No.: LCSA04225113EA 6.2. Disturbance Calculation The AC mains conducted disturbance is calculated by adding the 10dB Pulse Limiter and Cable Factor and Duty Cycle Correction Factor (if any) from the measured reading. The basic equation with a sample calculation is as follows: Correct Factor=Lisn Factor+Cable Factor+Insertion loss of Pulse Limitter CD (dBuV) = RA (dBuV) + PL (dB) + CL (dB) Where CD = Conducted Disturbance RA = Reading Amplitude CL = Cable Attenuation Factor (Cable Loss) PL = 10 dB Pulse Limiter Factor 6.3. Standard Applicable According to §15.207: For all the consumer devices which is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies within the band 150 kHz to 30 MHz shall not exceed 250 microvolts (The limit decreases linearly with the logarithm of the frequency in the range 0.15 MHz to 0.50 MHz). The limits at specific frequency range are listed as follows: Frequency Range (MHz) 0.15 to 0.50 0.50 to 5 5 to 30 Quasi-peak 66 to 56 56 60 Limits (dBV) * Decreasing linearly with the logarithm of the frequency 6.4 Test Results PASS Average 56 to 46 46 50 The test data please refer to following page.

Field Strength Calculation The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting the Amplifier Gain and Duty Cycle Correction Factor (if any) from the measured reading. The basic equation with a sample calculation is as follows: FS (dBuV/m) = RA (dBuV) + AF (dB/m) + CL (dB) AG (dB) Where FS = Field Strength RA = Reading Amplitude AF = Antenna Factor CL = Cable Attenuation Factor (Cable Loss) AG = Amplifier Gain 7.5. Operating Condition of EUT (1) Setup the EUT as shown in Section 7.1. (2) Let the EUT work in worst test mode1 and measure it. 7.6. Measuring Setting The following table is the setting of spectrum analyzer and receiver. Receiver Parameter Attenuation Start ~ Stop Frequency Start ~ Stop Frequency Start ~ Stop Frequency Setting Auto 9kHz~150kHz / RB 200Hz for QP/Average 150kHz~30MHz / RB 9kHz for QP/Average 30MHz~1000MHz / RB 100kHz for QP 7.7. Test Procedure 1) Sequence of testing 9 kHz to 30 MHz Setup: --- The equipment was set up to simulate a typical usage like described in the user manual or described by manufacturer. --- If the EUT is a tabletop system, a rotatable table with 0.8 m height is used. --- If the EUT is a floor standing device, it is placed on the ground. --- Auxiliary equipment and cables were positioned to simulate normal operation conditions. --- The AC power port of the EUT (if available) is connected to a power outlet below the turntable. --- The measurement distance is 3 meter. --- The EUT was set into operation. Premeasurement: --- The turntable rotates from 0° to 315° using 45° steps. --- The antenna height is 1 meter. --- At each turntable position the analyzer sweeps with peak detection to find the maximum of all emissions Final measurement: --- Identified emissions during the premeasurement the software maximizes by rotating the turntable Shenzhen LCS Compliance Testing Laboratory Ltd.

Also a plot with the graph of the premeasurement and the limit will be stored. 2) Sequence of testing 30 MHz to 1 GHz Setup: --- The equipment was set up to simulate a typical usage like described in the user manual or described by manufacturer. --- If the EUT is a tabletop system, a table with 0.8 m height is used, which is placed on the ground plane. --- If the EUT is a floor standing device, it is placed on the ground plane with insulation between both. --- Auxiliary equipment and cables were positioned to simulate normal operation conditions --- The AC power port of the EUT (if available) is connected to a power outlet below the turntable. --- The measurement distance is 3 meter. --- The EUT was set into operation. Premeasurement: --- The turntable rotates from 0° to 315° using 45° steps. --- The antenna is polarized vertical and horizontal. --- The antenna height changes from 1 to 3 meter. --- At each turntable position, antenna polarization and height the analyzer sweeps three times in peak to find the maximum of all emissions. Final measurement: --- The final measurement will be performed with minimum the six highest peaks. --- According to the maximum antenna and turntable positions of premeasurement the software maximize the peaks by changing turntable position (± 45°) and antenna movement between 1 and 4 meter. --- The final measurement will be done with QP detector with an EMI receiver. --- The final levels, frequency, measuring time, bandwidth, antenna height, antenna polarization, turntable angle, correction factor, margin to the limit and limit will be recorded. Also a plot with the graph of the premeasurement with marked maximum final measurements and the limit will be stored. 7.8. Test Results PASS.

Block Diagram of Test Setup Report No.: LCSA04225113EA 8.2. Test Procedure Use the following spectrum analyzer settings: Span = 10Hz RBW =30Hz VBW = 1KHz Sweep = auto Detector function = peak Trace = max hold The EUT should be transmitting at its maximum data rate. Allow the trace to stabilize. Use the marker-to-peak function to set the marker to the peak of the emission. Use the marker-delta function to measure 20 dB down one side of the emission. Reset the marker-delta function, and move the marker to the other side of the emission, until it is (as close as possible to) even with the reference marker level. The marker-delta reading at this point is the 20 dB bandwidth of the emission. If this value varies with different modes of operation (e.g., data rate, modulation format, etc.), repeat this test for each variation. The limit is specified in one of the subparagraphs of this Section. Submit this plot(s). Shenzhen LCS Compliance Testing Laboratory Ltd.
