The factors contributing to uncertainties are spectrum analyzer, cable loss, and LISN. The Treatment of Uncertainty in EMC Measurements, the best estimate of the uncertainty of any conducted emissions measurement at ATC is +2.23dB. 4.7.Test Procedure The EUT is put on the plane 0.8m high above the ground by insulating support and is connected to the power mains through a line impedance stabilization network (L.I.S.N.). This provides a 50ohm coupling impedance for the EUT system. Please refer the block diagram of the test setup and photographs. Both sides of AC lines are checked to find out the maximum conducted emission. In order to find the maximum emission levels, the relative positions of equipment and all of the interface cables shall be changed according to ANSI C63.4: 2014 on Conducted Emission Measurement. The bandwidth of test receiver (R & S ESCS30) is set at 9kHz. The frequency range from 150kHz to 30MHz is checked. Shenzhen Accurate Technology Co., Ltd.

For example, a margin of -7dB means the emission is 7dB below the limit. Shenzhen Accurate Technology Co., Ltd.

Report No.: ATE20172401 Page 18 of 27 5.6.Test Procedure The EUT and its simulators are placed on a turntable, which is 0.8 meter high above ground. The turntable can rotate 360 degrees to determine the position of the maximum emission level. EUT is set 3.0 meters away from the receiving antenna, which is mounted on an antenna tower. The antenna can be moved up and down between 1.0 meter and 4 meters to find out the maximum emission level. Broadband antenna (calibrated bilog antenna) is used as receiving antenna. Both horizontal and vertical polarizations of the antenna are set on measurement. In order to find the maximum emission levels, all of the interface cables must be manipulated according to ANSI C63.4: 2014 on radiated emission measurement. The bandwidth of the EMI test receiver (R&S ESCS30) is set at 120kHz. The frequency range from 9kHz to 12750MHz is checked. Note: The EUT highest operating frequency provided by Manufacturer is 2464.5MHz, the radiated emission measurement shall be made up to 12.75GHz. Shenzhen Accurate Technology Co., Ltd.

Report No.: ATE20172401 Page 19 of 27 5.7.Radiated Emission Noise Measurement Result PASS. The frequency range from 9kHz to 12750MHz is investigated. The radiation emissions from 9kHz-30MHz is not reported, because the test values lower than the limits of 20dB. The spectral diagrams are attached as below. Shenzhen Accurate Technology Co., Ltd.
