The measuring distance of at 3 m shall be used for measurements at frequency up to 1GHz. For frequencies above 1GHz, any suitable measuring distance may be used. b. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter open area test site. The table was rotated 360 degrees to determine the position of the highest radiation. c. The height of the equipment or of the substitution antenna shall be 0.8 m; the heigh t of the test antenna shall vary between 1 m to 4 m. Both horizontal and vertical polarizations of the antenna are set to make the measurement. d. The initial step in collecting conducted emission data is a spectrum analyzer peak detector mode pre-scanning the measurement frequency range. Significant peaks are then marked and then Quasi Peak detector mode re-measured. e. If the Peak Mode measured value compliance with and lower than Quasi Peak Mode Limit, the EUT shall be deemed to meet QP Limits and then no additional QP Mode measurement performed. f. For the actual test configuration, please refer to the related Item EUT Test Photos. Note:
Both horizontal and vertical antenna polarities were tested and performed pretest to three orthogonal axis.

Report No.: BCTC-FY 190704201E 4. 100 KHZ BANDWIDTH OF FREQUENCY BAND EDGE APPLICABLE STANDARD Emissions radiated outside of the specified frequency bands, except for harmonics, shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission limits in 15.209, whichever is the lesser attenuation TEST PROCEDURE a) Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. b) Position the EUT without connection to measurement instrument. Turn on the EUT and connect its antenna terminal to measurement instrument via a low loss cable. Then set it to any one measured frequency within its operating range, and make sure the instrument is operated in its linear range. c) i) VBW for Peak, Quasi-peak, or Average Detector Function: 3 RBW d) Repeat above procedures until all measured frequencies were complete. Note:
Both horizontal and vertical antenna polarities were tested and performed pretest to three orthogonal axis. The worst case emissions were reported 4.1 DEVIATION FROM STAND ARD No deviation. 4.2 TEST SETUP 4.3 EUT OPERATION CONDITIONS The EUT tested system was configured as the statements of 2.4 Unless otherwise a special operating condition is specified in the follows during the testing. 4.4 TEST RESULTS Test Report Tel: 400-788-9558 Web: https://www.bctc-lab.com BCTC/RF-EMC-007 Ver.A.0 Page 25 of 33 S henzhen B CTC Testing Co., Ltd.

BANDWIDTH TEST 5.1 APPLIED PROCEDURES / LIMIT FCC Part15 (15.249) , Subpart C Section Test Item 15.249 Bandwidth Frequency Range
(MHz) 900~928 Result PASS 5.1.1 TEST PROCEDURE 1. Set resolution bandwidth (RBW) = 1-5% or DTS BW, not to exceed 100 kHz. 2. Set the video bandwidth (VBW) 3 x RBW. 3. Detector = Peak. 4. Trace mode = max hold. 5. Sweep = auto couple. 6. Allow the trace to stabilize. 7. Measure the maximum width of the emission that is constrained by the frequencies associated with the two outermost amplitude points (upper and lower) that are attenuated by 6 dB relative to the maximum level measured in the fundamental emission. 5.1.2 DEVIATION FROM STAND ARD No deviation. 5.1.3 TEST SETUP 5.1.4 EUT OPERATION CONDITIONS The EUT tested system was configured as the statements of 2.4 Unless otherwise a special operating condition is specified in the follows during the testing.
