TEST REPORT Report No. : AW0041256(7) Date : July 20, 2018 2 Description of the radiated emission test 2.1 Test Procedure Radiated emissions measurements are investigated and taken pursuant to the procedures of ANSI C63.10 – 2013. A non-conductive turntable with dimensions of 1.5m x 0.4m x 0.8m (L x W x H) placed above the reference ground plane. The equipment under test (EUT) was placed at 0.8m height for below 1GHz measurement and 1.5m height for above 1GHz measurement. The test distance is 3m between EUT and receiving antenna. A broadband antenna mounting on the mast received the signal strength. The turntable was rotated to maximize the emission level. The antenna was moving along the mast from 1m up to 4m until no more higher value was found. Both horizontal and vertical polarization of the antenna were placed and investigated. Additional absorbing material will be placed between the EUT and receiving antenna for above 1GHz measurement. For below 30MHz, a loop antenna with its vertical plane is placed 3m from the EUT and rotated about its vertical axis for maximum response at each azimuth about the EUT. And the centre of the loop shall be 1 m above the ground. The device was rotated through three orthogonal axes to determine which attitude and configuration produce the highest emission during measurement.

TEST REPORT Report No. : AW0041256(7) Date : July 20, 2018 2.3 Test Result Peak Detector data was measured unless otherwise stated. The radiated emissions are measured from 9kHz to 26GHz (the tenth harmonics) The worst case configuration is shown on the worst case configuration of test setup photo. The frequencies from fundamental up to tenth harmonics were investigated, and emissions more 20dB below limit were not reported. Thus, those highest emissions were presented in next pages. The EUT has been tested in Transmission mode. It was found that the EUT meet the FCC and RSS requirement. Page 10 of 20 FCC ID: OTM-8447118-24GTX IC: 20978-844711824G
