Report No.：ED10050058-1 3.4.EUT Configuration on Measurement The following equipment are installed on Radiated Emission Measurement to meet the commission requirements and operating regulations in a manner which tends to maximize its emission characteristics in normal application. 8DN Weather Sation (EUT) Model Number : DPF8WS-WA 3.5.Operating Condition of EUT 3.5.1 Setup the EUT as shown in Section 3.2. 3.5.2 Turn on the power of all equipment. 3.5.3 Let the EUT work in test mode (Connect to PC) and measure it. 3.6.Test Procedure EUT and its simulators are placed on a turntable, which is 0.8 meter high above ground. The turn table can rotate 360 degrees to determine the position of the maximum emission level. EUT is set 3.0 meters away from the receiving antenna, which is mounted on a antenna tower. The antenna can be moved up and down between 1.0 meter and 4 meters to find out the maximum emission level. Broadband antenna (calibrated bilog antenna) is used as receiving antenna. Both horizontal and vertical polarization of the antenna is set on measurement. In order to find the maximum emission levels, all of the interface cables must be manipulated according to ANSI C63.4-2003 on radiated emission measurement. The bandwidth of the EMI test receiver (R&S ESCI) set at 120KHz in 30MHz to 1000MHz, set at 1MHz above 1000MHz. The frequency range from 30MHz to 1000MHz is checked. 3.7.Radiated Emission Noise Measurement Results PASS. The scanning waveforms refer to the following pages: Page 14 of 20
