Test Report 18070525-FCC-R1 Page No. 51 of 75 6.6 Spurious Radiated Emissions Temperature 26 oC Relative Humidity 57% Atmospheric Pressure 1018mbar Test date : May 21, 2018 Tested By : Aaron Liang Requirement(s): Spec Item Requirement Applicable The power of any emission outside of the authorized §2.1053, operating frequency ranges must be attenuated below the §22.917 & a) transmitter power (P) by a factor of at least 43 + 10 log (P) §24.238 dB. The spectrum is scanned from 30 MHz up to a frequency including its 10th harmonic. Test setup 1. The transmitter was placed on a wooden turntable, and it was transmitting into a non- radiating load which was also placed on the turntable. 2. The measurement antenna was placed at a distance of 3 meters from the EUT. During the tests, the antenna height and polarization as well as EUT azimuth were varied in order to identify the maximum level of emissions from the EUT. The test Test was performed by placing the EUT on 3-orthogonal axis. 3. Remove the EUT and replace it with substitution antenna. A signal generator was Procedure connected to the substitution antenna by a non-radiating cable. The absolute levels of the spurious emissions were measured by the substitution. Sample Calculation: EUT Field Strength = Raw Amplitude (dBµV/m) – Amplifier Gain (dB) + Antenna Factor (dB) + Cable Loss (dB) + Filter Attenuation (dB, if used)
