FCC SAR TEST REPORT
Report No. : FA9O2119
19. Uncertainty Assessment
Per KDB 865664 D01 SAR measurement 100MHz to 6GHz, when the highest measured 1-g SAR within a frequency
band is < 1.5 W/kg and the measured 10-g SAR within a frequency band is < 3.75 W/kg. The expanded SAR
measurement uncertainty must be ≤ 30%, for a confidence interval of k = 2. If these conditions are met, extensive
SAR measurement uncertainty analysis described in IEEE Std 1528-2013 is not required in SAR reports submitted
for equipment approval. For this device, the highest measured 1-g SAR is less 1.5W/kg. Therefore, the measurement
uncertainty table is not required in this report.
