FCC_15.247_DTS_v2.0 Test Methodology Radiated Emission The radiated emission measurements of the transmitter part were performed according to the procedures in ANSI C63.10-2013. For measurement below 1GHz - the equipment under test (EUT) was placed at the middle of the 80 cm height turntable. For measurement above 1GHz - the EUT was placed at the middle of the 1.5 m height turntable and RF absorbing material was placed on ground plane between turntable and measuring antenna. During the testing, the EUT was operated standalone and arranged for maximum emissions. The EUT was tested in three orthogonal planes. The investigation is performed with the EUT rotated 360 ﾟ, the antenna height scanned between 1m and 4m, and the antenna rotated to repeat the measurements for both the horizontal and vertical antenna polarizations. Repeat the measurement steps until the maximum emissions were obtained. All radiated tests were performed at an antenna to EUT with 3 meters distance, unless stated otherwise in particular parts of this test report. Field Strength Calculation The field strength at 3 m was established by adding the meter reading of the spectrum analyzer to the factors associated with antenna correction factor, cable loss, preamplifiers and filter attenuation. The equation is expressed as follow: FS = R + AF + CF + FA – PA Where FS = Field Strength in dBuV/m at 3 meters. R = Reading of Spectrum Analyzer in dBuV. AF = Antenna Factor in dB. CF = Cable Attenuation Factor in dB. FA = Filter Attenuation Factor in dB. PA = Preamplifier Factor in dB. FA and PA are only be used for the measuring frequency above 1 GHz.
