The problems include the use of old test instruments and uninspiring coursework. Updating the hardware is expensive and it’s difficult to maintain them. The shortcoming of traditional experimental instruments is increasingly obvious. To improve the facilities for use in these courses and provide innovation to teaching methods, the thesis introduces Visual Instrumens to experiment teaching. Here, a computer takes the place of many traditional instruments, and can complete the test task with minimal accessorial hardware. Focusing on the demand of teaching, the thesis gives the design idea and structure of the teaching platform based on Visual Instruments, and constructs the platform using LabVIEW with existing hardware. The teaching platform uses modularization which provides the characteristics of opening architecture, flexibility and convenience. The system is composed of three parts: the Signal Analyzer, the Signal Generator and the Demonstration Unit. The Signal Analyzer may analyze deterministic signal and stochastic signal according to their diferent characteristics. The Signa Generator will generate many useful signals. The Demonstration Unit provides some common experiments which can help to finish teaching task without other hardware. The thesis desctibes the elements and method of realization of the three parts, and provides examples of the typical experiments for which the platform can be used.
