Page 13 of 49 Report No.: 180320001RFC-3 4.5.3 For Conducted RF test setup 4.6 SYSTEM TEST CONFIGURATION For emissions testing, the equipment under test (EUT) setup to transmit continuously to simplify the measurement methodology. Care was taken to ensure proper power supply voltages during testing. During testing, radiated emission were performed with the EUT set to transmit at the channel with highest output power as worst-case scenario. It was powered by a 120~60Hz. Only the worst case data were recorded in this test report. The signal is maximized through rotation and placement in the three orthogonal axes. The antenna height and polarization are varied during the search for maximum signal level. The antenna height is varied from 1 to 4 meters. Radiated emissions are taken at three meters unless the signal level is too low for measurement at that distance. If necessary, a pre-amplifier is used and/or the test is conducted at a closer distance. Therefore, all final radiated testing was performed with the EUT in (see table below) orientation. Worst-case axis Frequency Mode Antenna Port positioning Above 1GHz 1TX Chain 0 Y axis All readings are extrapolated back to the equivalent three meter reading using inverse scaling with distance. Analyzer resolution is 100 kHz or greater for frequencies below 1000 MHz. The resolution is 1 MHz or greater for frequencies above 1000 MHz. The spurious emissions more than 20 dB below the permissible value are not reported. Radiated emission measurement were performed from the lowest radio frequency signal generated in the device which is greater than 9 kHz to the tenth harmonic of the highest fundamental frequency or to 40 GHz, whichever is lower.

Except as shown in paragraph (c) of this section, if transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1), (b)(2), and (b)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi. EUT Antenna: Antenna in the interior of the equipment and no consideration of replacement. The gain of the antenna is 1.5 dBi. Shenzhen UnionTrust Quality and Technology Co., Ltd.

Test Procedure: 1. Remove the antenna from the EUT and then connect a low loss RF cable from the antenna port to the power meter. 2. Measure out each test modes’ peak or average output power, record the power level. Note: The cable loss and attenuator loss were offset into measure device as an amplitude offset. Test Setup: Refer to section 4.4.3 for details. Instruments Used: Refer to section 3 for details Test Mode: Transmitter mode Test Results: Pass Test Data: Mode Channel/ Frequency (MHz) Maximum Conducted Peak Power (dBm) 1(2412) 18.57 IEEE 802.11b 6(2437) 18.59 11(2462) 18.92 1(2412) 24.13 IEEE 802.11g 6(2437) 24.44 11(2462) 24.62 1(2412) 20.67 IEEE 802.11n-HT20 6(2437) 21.49 11(2462) 22.37 3(2422) 19.87 IEEE 802.11n-HT40 6(2437) 20.33 9(2452) 20.43 Shenzhen UnionTrust Quality and Technology Co., Ltd.

Use the following spectrum analyzer settings: a) Set RBW = 100 kHz. b) Set the video bandwidth (VBW) ≥ 3 x RBW. c) Detector = Peak. d) Trace mode = max hold. e) Sweep = auto couple. f) Allow the trace to stabilize. g) Measure the maximum width of the emission that is constrained by the frequencies associated with the two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 dB relative to the maximum level measured in the fundamental emission. Note: The cable loss and attenuator loss were offset into measure device as an amplitude offset. Test Setup: Refer to section 4.4.3 for details.
