Carrier Frequency of Channels Description of Channel: Channel Frequency (MHz) Channel Frequency (MHz) 1 910 2 920 2.3. Operation of EUT During Testing Operating Mode The mode is used: Transmitting mode Low Channel: 910MHz High Channel: 920MHz 2.4. Description of Test Setup Operation of EUT during testing: The sample was placed (0.8m below 1GHz, 1.5m above 1GHz) above the ground plane of 3m chamber. Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, rotating the turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. The worst case is X position. EUT Page 9 of 27 Report No.: HK2208183675-…
