Test Report No.: RF180717N013-2 4.2. RADIATED EMISSION AND BANDEDGE MEASUREMENT 4.2.1 LIMITS OF RADIATED EMISSION AND BANDEDGE MEASUREMENT The field strength of any emissions shall not exceed the following limits: (a)15.848mV/m(84dBuV/m) at 30m, within the band 13.553-13.567 MHz; (b)334uV/m(50.5dBuV/m) at 30m, within the band 13.410-13.553 MHz and 13.567-13.710MHz; (c)106uV/m(40.5dBuV/m) at 30m, within the band 13.110-13.410 MHz and 13.710-14.010MHz; The field strength of any emissions appearing outside of the 13.110-14.010 MHz band shall not exceed the general radiated emission limits in § 15.209. FIELD STRENGTH MEASUREMENT DISTANCE FREQUENCIES (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 NOTE: 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 8593 5656 Bureau Veritas Shenzhen Co., Ltd.

Test Report No.: RF180717N013-2 4.2.3 TEST PROCEDURES a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3&10 meter 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 quasi-peak detect function and specified bandwidth with maximum hold mode when the test frequency is below 1 GHz. f. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, For battery operated equipment, the equipment tests shall be perform using fresh batteries. The turntable was rotated to maximize the emission level. g. 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. NOTE: 1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120kHz for Quasi-peak detection at frequency below 1GHz. 2. The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz and video bandwidth is 3MHz for Peak detection at frequency above 1GHz. 3. All modes of operation were investigated and the worst-case emissions are reported. 4.2.4 DEVIATION FROM TEST STANDARD No deviation.
