EMI Test System with 9KHz to 300MHz EMI Receiver and Artificial Mains Network
1. Introduction
Electromagnetic Interference (EMI) refers to the interference phenomenon caused by the action of electromagnetic waves and electronic components, includes conduction interference and radiation interference. Conducted interference refers to the coupling (interference) of signals on one electrical network to another electrical network through a conductive medium. Radiated interference means that the interference source couples (interferes) its signal to another electrical network through space. In high-speed PCB and system design, high-frequency signal lines, integrated circuit pins, various types of connectors, etc. may become antennas. A characteristic source of radiated interference that emits electromagnetic waves and affects the normal operation of other systems or other subsystems within the system.
The EMI test system includes:

2. Preparation:
1). Lab: no less than 4m*6m. As far as possible in the first floor, and there is wet mud outside the door all year round. Or there is water pipe with material of galvanization or cast iron, in order to use as a signal ground.
2). Test bench: 2 tables, one for EMC500, the other for computer and printer
3). Wooden bench: 1 wooden table for EUT with size of 1000mm*2000mm*400mm (W*L*H)
4). Aluminium plate: two pieces for reference plate with size of 2000mm*1000mm*(2~3)mm (L*W*thickness)
5). Insulating plate: 1 piece for EUT with size of 2000mm*1000mm*(10~14)mm (L*W*thickness)
6). Computer: 1 set with at least 1 RS232C port.
