No.I19Z60716-EMC01 Page 13 of 23 ANNEX A: MEASUREMENT RESULTS A.1 Radiated Emission Reference FCC: CFR Part 15.109(a). A.1.1 Method of measurement The field strength of radiated emissions from the unintentional radiator (USB mode of EUT and charging mode of EUT) at distances of 10 meters(for 30MHz-1GHz) and 3 meters (for above 1GHz) is tested. Tested in accordance with the procedures of ANSI C63.4 – 2014, section 8.3. The EUT was placed on a non-conductive table. The measurement antenna was placed at a distance of 3/10 meters from the EUT. During the tests, the antenna height and the EUT azimuth were varied in order to identify the maximum level of emissions from the EUT. This maximization process was repeated with the EUT positioned in each of its three orthogonal orientations. A.1.2 EUT Operating Mode The EUT is operating in the USB mode and charging mode. During the test EUT is connected to a PC via a USB cable in the case of USB mode and is connected to a charger in the case of charging mode. The model of the PC is DELL OPTIPLEX 380, and the serial number of the PC is 2X1YV2X. The software is used to let the PC keep on copying data to EUT, reading and erasing the data after copy action was finished. Note：I/O information：Printer – USB, Mouse – PS/2, Keyboard – USB.

No.I19Z60716-EMC01 Page 14 of 23 A.1.5 Measurement Results A "reference path loss" is established and the ARpl is the attenuation of “reference path loss”. It includes the antenna factor of receive antenna and the path loss. The measurement results are obtained as described below: Result = PMea + ARpl = PMea + GA + GPL Where GA: Antenna factor of receive antenna GPL: Path Loss PMea: Measurement result on receiver. Measurement uncertainty (worst case): U = 5.44 dB, k=2.
