According to the requirements in Section 6 of ANSI C63.10: 2013. Conducted emissions from the EUT measured in the frequency range between 0.15 MHz and 30MHz using CISPR 16-1-1 Quasi-Peak and Average detector mode. 2.3.2 Radiated Emissions The EUT is a placed on as turn table which is 0.8 m/1.5m (frequency above 1GHz) above ground plane.

Conducted Emission at antenna port: Refer to section 6.2 for details. 8.2.2. Radiated emission: Refer to section 7.2 for details. 8.3 Test SET-UP: Refer to section 7.3 for details. 8.4 Measurement Procedure: 1 The EUT was placed on a turn table which is 0.8m above ground plane. 2 The turn table shall rotate 360 degrees to determine the position of maximum emission level. 3 EUT is set 3m away from the receiving antenna which varied from 1m to 4m to find out the highest emissions. 4 When measurement procedures for electric field radiated emissions above 1 GHz the EUT measurement is to be made "while keeping the antenna in the `cone of radiation' from that area and pointed at the area both in azimuth and elevation, with polarization oriented for maximum response." is still within the 3dB illumination BW of the measurement antenna. 5 Maximum procedure was performed on the six highest emissions to ensure EUT compliance. 6 And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. 7 Repeat above procedures until all frequency measured were complete.
