TEST METHODOLOGY The measurement procedure described in the ˑAmerican National Standard of Procedures for Compliance Testing of Unlicensed Wireless Devices˒ (ANSI C63.10-2020) was used for the devices operating under 47 CFR Part 95 Subpart M. 2.1 EUT CONFIGURATION The EUT configuration for testing is installed on EIRP measurement to meet the Commissions requirement and operating in a manner that intends to maximize its emission characteristics in a continuous normal application. 2.2 EUT EXERCISE The EUT was operated in the engineering mode to fix the Tx Frequency that was for the purpose of the measurements. 2.3 GENERAL TEST PROCEDURES Radiated Emissions The EUT is placed on a turn table, which is 0.8 m above the ground plane below 1 GHz and 1.5 m above 1 GHz with absorbers between the EUT and receiving antenna. The turntable shall rotate 360 degrees to determine the position of maximum emission level. EUT is set far-field distance away from the receiving antenna, which varied from 1 m to 4 m to find out the highest emission. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. In order to find out the max. emission, the relative positions of this hand-held transmitter (EUT) was rotated through three orthogonal axes according to the requirements in Section 8 of ANSI C63.10-2020. 2.4 DESCRIPTION OF TEST MODES The EUT has been tested under operating condition. Test program used to control the EUT for staying in continuous transmitting and receiving mode is programmed. The report shall not be (partly) reproduced except i…
