Research and Design of Virtual Oscilloscope Based on Android_QT

摘要

First of all, the paper would be introduce the study on portable virtual instrument technology based on the Android platform, then particularly in virtual oscilloscope as an example, focusing on the overall design of the system. Stratified in different signal acquisition system in order to meet the demands for different users; Using QT for efficient and flexible design of soft Panel, function modules and filters. The design can input dual-channel analog signal, then achieve the basic functions of an oscilloscope, like, set certain control parameters, real-time data acquisition, processing, display and storage.
