4. RADIATED DISTURBANCE TEST 4.1. Test Standard and Limit 4.1.1.Test Standard EN 55022:2006+A1:2007 4.1.2.Test Limit Table 5 Radiated Disturbance Test Limit (Class B) For EN55022 Frequency Limit (dbµv/m) Quasi-peak Level 30MHz~230MHz 40 230MHz~1000MHz 47 * The lower limit shall apply at the transition frequency. * The test distance is 3m. 4.2. Test Procedure The EUT is placed on a turntable, which is 0.8 meter above ground. The turntable can rotate 360 degrees to determine the position of the maximum emission level. EUT is set 3 meters away from the receiving antenna, which is mounted on an antenna tower. The antenna can move up and down between 1 to 4 meters to find out the maximum emission level. Broadband antenna is used as a receiving antenna. Both horizontal and vertical polarization of the antenna is set on test. 4.3. Test Arrangement The arrangement of the equipment is installed to meet the standards and operating in a manner, which tends to maximize its emission characteristics in a normal application. The detailed information refers to test picture. 4.4. Test Data Emissions don t show below are too low against the limits, the test curves are shown in the APPENDIX Shenzhen Meihua Electronic Technology Co., Ltd. Page 7 of 16

Test Procedure 5.2.1.Contact Discharge: The ESD generator is held perpendicular to the surface to which the discharge is applied and the tip of the discharge electrode touch the surface of EUT. Then turn the discharge switch. The generator is then re-triggered for a new single discharge and repeated 10 times for each pre-selected test point. This procedure shall be repeated until all the air discharge completed 5.2.2.Air Discharge: Air discharge is used where contact discharge can t be applied.. The round discharge tip of the discharge electrode shall be approached as fast as possible to touch the EUT. After each discharge, the discharge electrode shall be removed from the EUT. The generator is then re-triggered for a new single discharge and repeated 10 times for each pre-selected test point. This procedure shall be repeated until all the air discharge completed 5.2.3.Indirect discharge for horizontal coupling plane At least 10 single discharges shall be applied to the horizontal coupling plane, at points on each side of the EUT. 5.2.4.Indirect discharge for vertical coupling plane At least 10 single discharge shall be applied to the center of one vertical edge of the coupling plane. The coupling plane, of dimensions 0.5m X 0.5m, is placed parallel to, and positioned at a distance of 0.1m from the EUT. Discharges shall be applied to the coupling plane, with this plane in sufficient different positions that the four faces of the EUT are completely illuminated. 5.3.
