9.7 Spurious radiated emissions for transmitter Test Method 1: The EUT was place on a turn table which is 1.5m above ground plane for above 1GHz and 0.8m above ground for below 1GHz at 3 meter chamber room for test. The table was rotated 360 degrees to determine the position of the highest radiation. 2: The EUT was set 3 meters away from the interference – receiving antenna, which was mounted on the top of a variable – height antenna tower. 3: 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. 4: 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. 5: Use the following spectrum analyzer settings According to C63.10: For Above 1GHz Span = wide enough to capture the peak level of the in-band emission and all spurious RBW = 1MHz, VBW≥RBW for peak measurement and VBW = 10Hz for average measurement, Sweep = auto, Detector function = peak, Trace = max hold. For Below 1GHz Use the following spectrum analyzer settings: Span = wide enough to capture the peak level of the in-band emission and all spurious RBW = 100 KHz, VBW≥RBW for peak measurement, Sweep = auto, Detector function = peak, Trace = max hold. Note: 1: The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120 KHz for Quasi-peak detection (QP) at frequency below 1GHz. 2: The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and the video bandwidth is 3MHz for peak detection (PK) at frequency above 1GHz. 3: The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and the video bandwidth is 3MHz for RMS Average ((duty cycle ˂ 98%) for Average detection (AV) at frequency above 1GHz, then the measurement results was added to a correction factor (20log(1/duty cycle). 4: The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and the video bandwidth is 10Hz (duty cycle ˃ 98%) for Average detection (AV) at requencyabove1GHz Report Number: 64.790.18.04422.01 Page 29 of 34 TÜV SÜD Certification and Testing (China) Co., Ltd.

Spurious radiated emissions for transmitter According to C63.10, if the peak (or quasi-peak) measured value complies with the average limit, it is unnecessary to perform an average measurement, so AV emission value did not show in below table if the peak value complies with average limit. Transmitting spurious emission test result as below: Below 1GHz Emission Correct Frequency Frequency Polarization Limit Detector Margin Result Level factor Band MHz dBuV/m dBμV/m dB (dB) 341.962778 35.23 H 46.00 QP 10.77 -25.3 Pass 377.960556 38.01 H 46.00 QP 7.99 -24.5 Pass 30- 414.012222 39.00 H 46.00 QP 7.00 -23.7 Pass 1000MHz 40.292778 30.12 V 40.00 QP 9.88 -26.0 Pass 342.016667 33.89 V 46.00 QP 12.11 -25.3 Pass 413.958333 32.00 V 46.00 QP 14.00 -23.7 Pass Above 1GHZ Low channel 2402MHz Test Result Emission Correct Frequency Frequency Polarization Limit Detector Margin Result Level factor Band MHz dBuV/m dBμV/m dB (dB) 1452.125000 32.19 H 74 PK 41.81 -11.1 Pass 1994.062500 33.95 H 74 PK 40.05 -8.9 Pass 4804.687500 53.03 H 74 PK 20.97 3.7 Pass 1000- 10729.218750 42.42 H 74 PK 31.58 10.4 Pass 25000MHz 1804.625000 38.31 V 74 PK 35.69 -9.8 Pass 2057.625000 33.31 V 74 PK 40.69 -8.3 Pass 4804.687500 48.25 V 74 PK 25.75 3.7 Pass 7206.562500 43.74 V 74 PK 30.26 6.0 Pass Middle channel 2440MHz Test Result Emission Correct Frequency Frequency Polarization Limit Detector Margin Result Level factor Band MHz dBuV/m dBμV/m dB (dB) 1452.062500 34.69 H 74 PK 39.31 -11.1 Pass 1994.375000 34.39 H 74 PK 39.61 -8.9 Pass 4879.687500 50.99 H 74 PK 23.01 3.8 Pass 1000- 12133.125000 43.31 H 74 PK 30.69 12.3 Pass 25000MHz 1807.562500 36.96 V 74 PK 37.04 -9.8 Pass 2077.312500 37.61 V 74 PK 36.39 -8.3 Pass 4880.625000 48.62 V 74 PK 25.38 3.8 Pass 11921.718750 44.53 V 74 PK 29.47 12.0 Pass Report Number: 64.790.18.04422.01 Page 31 of 34 TÜV SÜD Certification and Testing (China) Co., Ltd.
