Report No.: AGC02724190503FE03 Page 11 of 27 7.2. MEASUREMENT PROCEDURE 1. The EUT was placed on the top of the turntable 0.8 or 1.5 meter above ground. The phase center of the receiving antenna mounted on the top of a height-variable antenna tower was placed 3 meters far away from the turntable. 2. Power on the EUT and all the supporting units. The turntable was rotated by 360 degrees to determine the position of the highest radiation. 3. The height of the broadband receiving antenna was varied between one meter and four meters above ground to find the maximum emissions field strength of both horizontal and vertical polarization. 4. For each suspected emissions, the antenna tower was scan (from 1 M to 4 M) and then the turntable was rotated (from 0 degree to 360 degrees) to find the maximum reading. 5. Set the test-receiver system to Peak or CISPR quasi-peak Detect Function with specified bandwidth under Maximum Hold Mode. 6. In case the emission is lower than 30MHz, loop antenna has to be used for measurement and the recorded data should be QP measured by receiver. High - Low scan is not required in this case. The following table is the setting of spectrum analyzer and receiver. Spectrum Parameter Setting Start ~Stop Frequency 9KHz~150KHz/RB 200Hz for QP Start ~Stop Frequency 150KHz~30MHz/RB 9KHz for QP Start ~Stop Frequency 30MHz~1000MHz/RB 120KHz for QP Receiver Parameter Setting Start ~Stop Frequency 9KHz~150KHz/RB 200Hz for QP Start ~Stop Frequency 150KHz~30MHz/RB 9KHz for QP Start ~Stop Frequency 30MHz~1000MHz/RB 120KHz for QP
