Design and Performance Analysis of Square Wave Generator Based on the NI ELVIS II+

A square wave generator project based on NI ELVIS II+ platform was designed for the lack of training of students in soft and hard collaborative virtual experiment teaching. According to the technical specifications of the square wave generator, the parameters of each component are determined by theoretical calculation. A simple square wave generator circuit is built on the NI ELVIS II+ electronic experimental platform, and the program is programmed by Lab VIEW to collect signals and display the result of parameter changes and verification with experimental data. Practice has proved that the NI ELVIS II+ platform and Lab VIEW Given the lack of training of students in software and hardware collaborative virtual experiment teaching, the square wave generator project based on NI ELVIS II+ platform was designed. According to the technical specifications of the square wave generator, the parameters of each component were determined by theoretical calculation. A simple square wave generator circuit was built on the NI ELVIS II+ electronic experimental platform, and the program was written by Lab VIEW to collect signals and display the result of parameter changes and verification with experimental data. Practice has proved that the NI ELVIS II+ platform and Lab VIEW software help students to analyze the circuit more conveniently and accurately, and encourage students to pursue independent innovation and solve the problem of not being able to select components to design and build circuits and learn systematically.
