HP-5517B Agilent

There are often many strong electrical equipment on the site of the computer control system,which will generate interference electromagnetic fields during the start-up and production process,in addition to electromagnetic waves and lightning interference from space propagation,and the influence of alternating magnetic fields around high-voltage transmission lines.The main interference propagation paths are:electric field coupling,magnetic field coupling,and common impedance coupling.

在计算机控制系统的现场往往有许多强电设备，它们在起动和生产过程中将产生干扰电磁场，另外还有来自空间传播的电磁波和雷电干扰，以及高压输电线周围交变磁场的影响等。干扰传播途径主要有：电场耦合、磁场耦合、公共阻抗耦合。
