Research and Realization of Electronic Measuring Instrument Based on Virtual Technology

摘要

This thesis focuses on electronic experiment teaching how to use the virtual instrument in-depth research, design virtual instrument based on the computer sound card. Virtual oscilloscope based on the use of producers and consumers of data collection mode, which solve the data acquisition and data processing simultaneously prone to data loss problems. This paper describes in detail how to set up the sound management software and sound card voltage calibration method. The virtual function signal generator and virtual oscilloscope were conducted a comprehensive test to verify the practicality of these two virtual instrument.
