Report No: CCISE181109303 6.6 Field strength of spurious radiation measurement Test Requirement: FCC part 22.917(a), FCC part 24.238(a) Test Method: ANSI/TIA-603-D 2010 Limit: -13dBm Test setup: Below 1GHz Above 1GHz Test Procedure: 1. The EUT was placed on an non-conductive turntable using a non- conductive support. The radiated emission at the fundamental frequency was measured at 3 m with a test antenna and EMI spectrum analyzer. 2. 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. 3. The frequency range up to tenth harmonic was investigated for each of three fundamental frequency (low, middle and high channels). Once spurious emission was identified, the power of the emission was determined using the substitution method. 4. The spurious emissions attenuation was calculated as the difference between radiated power at the fundamental frequency and the spurious emissions frequency. ERP / EIRP = S.G. output (dBm) + Antenna Gain(dB/dBi) – Cable Loss (dB) Test Instruments: Refer to section 5.8 for details Test mode: Refer to section 5.3 for details.

Set chamber temperature to 25°C. Use a variable DC power source to power the EUT and set the voltage to rated voltage. 2. Set the spectrum analyzer RBW low enough to obtain the desired frequency resolution and recorded the frequency. 3. Reduce the input voltage to specify extreme voltage variation (+/— 15%) and endpoint, record the maximum frequency change.
