| Abstract: | In the traditional oscilloscope courses,the authenticity of the student’s measurement results cannot be effectively judged.Aiming at this problem,this paper proposes and implements an oscilloscope experimental system based on embedded Linux system and TCP/IP protocol.The system is based on Linux and QT framework to design a graphical operation interface,it uses DDS technology to design digital signal source,create data transmission channel between student and teacher based on TCP/IP protocol.The system can monitor and inform the whole process of student experiments,and effectively improve the teaching efficiency of the oscilloscope experiment course. |
