WENZHOU MTLC ELECTRIC APPLIANCES CO., LTD. FCC ID: ZZH-MWS 7.4. EUT Configuration on Test 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. 7.5. Operating Condition of EUT 7.5.1.Setup the EUT as shown on Section 7.1 7.5.2.Turn on the power of all equipments. 7.5.3.Let the EUT work in test mode (RX) and measure it. 7.6. Test Procedure The EUT and its simulators are placed on a turntable, which is 0.8 meter high above ground. The turntable 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 an antenna tower. The antenna can be moved up and down between 1.0 meter and 4 meters to find out the maximum emission level. Calibrated Loop antenna is used as receiving antenna for frequencies below 30MHz, Calibrated Bilog antenna is used as receiving antenna for frequencies between 30 MHz and 1 GHz, Calibrated Horn antenna is used as receiving antenna for frequencies above 1000MHz. Both horizontal and vertical polarizations of the antenna are 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 test receiver is set at 9kHz in below 30MHz. and set at 120kHz in 30-1000MHz, and 1MHz in above 1000MHz. The frequency range from 9kHz to 2GHz is checked. The final measurement in band 9-90kHz, 110-490kHz and above 1000MHz is performed with Peak detector and Average detector. Except those frequency bands mention above, the final measurement for frequencies below 1000MHz is performed with Quasi Peak detector. Through three orthogonal axes to determine which attitude and equipment arrangement produces the 7.7. Test Result PASS BST FCC ID REPORT: BST12040063Y-1ER-3 Page 14/16
