Test Report No.: RF181019N001 4.1.3 TEST PROCEDURE The basic test procedure was in accordance with ANSI C63.4:2014 (section 7). a. The EUT was placed 0.4 meters from the conducting wall of the shielded room with EUT being connected to the power mains through a line impedance stabilization network (LISN). Other support units were connected to the power mains through another LISN. The two LISNs provide 50 Ohm/ 50uH of coupling impedance for the measuring instrument. b. Both lines of the power mains connected to the EUT were checked for maximum conducted interference. c. The frequency range from 150 kHz to 30 MHz was searched. Emission levels under (Limit – 20dB) were not recorded. NOTE: 1. Q.P. and AV. are abbreviations of quasi-peak and average individually. 2. "-": The Quasi-peak reading value also meets average limit and measurement with the average detector is unnecessary. 3. Margin value = Emission level - Limit value 4. Correction factor = Insertion loss + Cable loss 5. Emission Level = Correction Factor + Reading Value 4.1.4 DEVIATION FROM TEST STANDARD No deviation.

Test Report No.: RF181019N001 4.2.3 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 3 meters semi-anechoic chamber. 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 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. 4.2.4 DEVIATION FROM TEST STANDARD No deviation.

Test Report No.: RF181019N001 4.3.3 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. Record the frequency difference as the emission bandwidth. d. Repeat above procedures until all frequencies measured were complete. 4.3.4 DEVIATION FROM TEST STANDARD No deviation. 4.3.5 TEST SETUP EUT SPECTRUM ANALYZER 10dB ATTENUATION PAD No. 34, Chenwulu Section, Guantai Rd., Houjie Tel.: +86 769 8593 5656 Bureau Veritas Shenzhen Co., Ltd.
