TEST METHODOLOGY Generally the tests were performed according to the KDB558074 v03r02. And ANSI C63.10-2009 was used to reference appropriate EUT setup and maximizing procedures of radiated spurious emission and AC line conducted emission testing. 3.1 EUT Configuration The EUT configuration for testing is installed on RF field strength measurement to meet the Commissions requirement and operating in a manner that intends to maximize its emission characteristics in a continuous normal application. 3.2 EUT Exercise The EUT was operated in the engineering mode to fix the TX frequency that was for the purpose ofthe measurements. According to its specifications, the EUT must comply with the requirements of the Section 15.207, 15.209 and 15.247 under the FCC Rules Part 15 Subpart C. 3.3 General Test Procedures Conducted Emissions According to therequirements in Section 6.2 of ANSI C63.10, the EUT is placed on the turntable, which is 0.8 m above ground plane and the conducted emissions from theEUT are measured in the frequency range between 0.15 MHz and 30MHz using CISPR Quasi-peakand Average detector. Radiated Emissions The EUT is placed on a turntable, which is 0.8 m above ground plane. The turntable shall rotate360 degrees to determine the position of maximum emission level. EUT is set 3 m away from thereceiving antenna, which varied from 1 m to 4 m to find out the highest emission. And also, eachemission was to be maximized by changing the polarization of receiving antenna both horizontaland vertical. In order to find out the highest emission, the relative positions of this hand-heldtransmitter (EUT) was rotated through…
