METHOD OF MEASUREMENT 3. 1.Applicable Standard According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. According KDB680106 D01: RF Exposure Wireless Charging Apps v 03r01. 4. TEST RESULT 4.1. Conducted Emission at the Mains Terminals Test Note: Measurements should be made from all sides and the top of the primary/client pair, with the 15 cm measured from the center of the probe(s) to the edge of the device Test Procedure: a) The RF exposure test was performed on 360 degree turn table in anechoic chamber. b) The measurement probe was placed at test distance (15cm) which is between the edge of the charger and the geometric centre of probe. c) The turn table was rotated 360d degree to search of highest strength. d) The highest emission level was recorded and compared with limit as soon as measurement of each points were completed. e) The EUT were measured according to the dictates of KDB 680106v03r01.
