摘要
虚拟仪器代表了电子测量仪器的发展方向,而示波器是电子测量领域应用最广泛的一款时域测量仪器,因此将虚拟示波器的设计与制作引入到电子测量实践教学中,要求学生设计并制作一款基于STM32单片机的双通道虚拟示波器,根据示波器的性能指标等参数进行示波器方案的设计、论证以及软硬件电路的制作,并给出最终的测量结果。通过该实验学生可以深刻地理解虚拟示波器的工作原理以及虚拟仪器的概念,并有效地培养学生的创新能力、工程实践能力和团队协作能力。
Virtual instrument represents the future direction of the development of electronic measuring instruments , and os-cilloscope is the most widely used instrument for time domain measurement in the field of electronic measurement .Therefore, de-sign and implementation of virtual oscilloscope is introduced into the practice teaching of electronic measurement .Students are re-quired to design and produce a dual channel virtual oscilloscope based on STM32 microcontroller.Firstly, students need to deter-mine the best design plan according to the performance index requirements , then to make the software and hardware circuit and provide the test result.This experimentation can make students deeply understand the working principle of oscilloscope and the concept of virtual instrument, and can also cultivate the innovative ability, engineering practice ability and teamwork ability of students effectively.
