Electromagnetic compatibility (EMC) is very important for intelligent instruments, and it is an important guarantee for its reliable operation. The complexity of EMC is mainly reflected in how to quickly and accurately locate the disturbance source, effectively suppress the disturbance source, and correctly judge the disturbance coupling path. Intelligent instruments have similar hardware characteristics. In this paper, the characteristics of common hardware characteristics of disturbance source and coupling path are analyzed, the equivalent antenna model of disturbance is analyzed, and the disturbance suppression method is given. Finally, the correctness of the method is verified by experiments.
