Open source and low cost virtual instrumentation system for teaching of electronics in technical education

This article presents a self-development virtual instrumentation system for teaching of electronics in technical education. The system reproduces the operation of a real function generator and oscilloscope and students can use it freely both at school and at home. The system consists of a software package that runs on different platforms and operating systems (windows and linux) with an optional external module connected by usb. All programs are open source, so there is no cost for students. It is in process of development an external unit that can be built by students at a very low cost, significantly improving system performance.
