Research on EMC Improvement of Digital-display Joystick

The general structure of the digital display joystick and the EMC radiation test requirements specified by GJB151B-2013 are introduced in this paper, the disturbance source and over-limits principle of electromagnetic mission are analyzed. Based on the analysis of the products, the general methods for improving the radiation disturbance of RE102 are summarized, and the effectiveness of the rectification method is proved by experiments. This paper provides an application for the EMC design of products, which also has a certain engineering significance of solving EMC problem.
