Test Report No.: RF190730N036 4 EMISSION TEST 4.1 RADIATED EMISSION MEASUREMENT 4.1.1 LIMITS OF RADIATED EMISSION MEASUREMENT TEST STANDARD: FCC Part 15, Subpart C, Section 15.209 Emissions radiated outside of the specified bands, shall be according to the general radiated limits as following: FREQUENCIES FIELD STRENGTH MEASUREMENT DISTANCE (MHz) (microvolts/meter) (meters) 0.009 – 0.490 2400/F(kHz) 300 0.490 – 1.705 24000/F(kHz) 30 1.705 – 30.0 30 30 30 – 88 100 3 88 – 216 150 3 216 - 960 200 3 Above 960 500 3 NOTES: 1. The lower limit shall apply at the transition frequencies. 2. Emission level (dBuV/m) = 20 log Emission level (uV/m). 3. As shown in 15.35(b), for frequencies above 1000MHz, the field strength limits are based on average detector, however, the peak field strength of any emission shall not exceed the maximum permitted average limits, specified above by more than 20dB under any condition of modulation. 4. The measured field strength was extrapolated to distance 30 meters, using the formula that the limit of field strength varies as the inverse distance square (40dB per decade of distance) Example: 13.56MHz = 15848uV/m 30m = 84dBuV/m 30m = 84+20log(30/3)2 3m = 124dBuV/m No. 34, Chenwulu Section, Guantai Rd., Houjie Tel: +86 769 8998 2098 Bureau Veritas Shenzhen Co., Ltd.

Test Report No.: RF190730N036 4.1.3 TEST PROCEDURE < Below 30MHz > a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 10 meters Semi-anechoic chamber room. The table was rotated 360 degrees to determine the position of the highest radiation. b. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top of a variable-height antenna tower. c. The height of antenna is varied from one meter to four meters above the ground to determine the maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are set to make the measurement. d. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from 1 meter to 4 meters and the rotatable table was turned from 0 degrees to 360 degrees to find the maximum reading. e. The test-receiver system was set to quasi-peak detect function and specified bandwidth with maximum hold mode when the test frequency is below 1 GHz. f. For below 30MHz, a loop antenna with its vertical plane is place 3m from the EUT and rotated about its vertical axis for maximum response at each azimuth about the EUT. And the centre of the loop shall be 1m above the ground. <30MHz~1GHz > a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 10 meters semi-anechoic chamber. The table was rotated 360 degrees to determine the position of the highest radiation. b. The EUT was set 10 meters away from the interference-receiving antenna, which was mounted on the top of a variable-height antenna tower. c. The antenna is a broadband antenna, and its height is varied from one meter to four meters above the ground to determine the maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are set to make the measurement. d. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from 1 meter to 4 meters and the rotatable table was turned from 0 degrees to 360 degrees to find the maximum reading. e. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode. NOTE: 1. The resolution bandwidth of test receiver/spectrum analyzer is 120kHz for Quasi-peak detection (QP) at frequency below 1GHz. 2. Emission level(dBuV/m)=Raw Value(dBuV) + Correction Factor(dB/m) 3. Correction Factor(dB/m) = Antenna Factor (dB/m) + Cable Factor (dB) 4. Margin value = Emission level – Limit value. 4.1.4 DEVIATION FROM TEST STANDARD No deviation.

The test was performed in RF Oven room. 2. The calibration interval of the above test instruments is 12 months and the calibrations are traceable to CEPREI/CHINA, GRGT/CHINA and NIM/CHINA. 4.2.3 TEST PROCEDURE a. Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. b. 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. c. Measure the frequency difference of two frequencies that were attenuated 20dB from the reference level.
