Description

technical field [0001] The invention relates to a general electromagnetic susceptibility testing device and testing method based on bus technology, belonging to the field of computer measurement and control. Background technique [0002] As a resource, electromagnetic waves have been widely used in the wide frequency range from very low frequency to microwave band. However, the accompanying electromagnetic interference is pervasively radiated or conducted to the operating electronic equipment, systems and the surrounding environment. . In military aviation and aerospace systems, including missile or rocket launching spacecraft devices, the electromagnetic compatibility and reliability of the entire system play a very important role. Various components, subsystems and full systems are subjected to extensive Electromagnetic Susceptibility (EMS) testing prior to system assembly and configuration. [0003] However, the current electromagnetic susceptibility test systems are ge...
