摘要
为了满足学生随时随地、方便快捷的搭建电类实验测试系统的目的,基于FPGA和Lab VIEW开发平台,设计了一种适用于实验教学的USB接口便携式虚拟示波器。给出了仪器的系统架构及软硬件设计方法,应用测试表明,该仪器性能稳定、波形良好,满足了电类实验教学的需求。在综合设计性实验和创新性实践计划中的教学应用实践证明该虚拟示波器可显著提升实验教学质量。
To achieve the goal of setting up an electronic test system conveniently, efficiently, and whenever and wherever possible. This paper explores the design of a portable virtual oscilloscope which is suitable for being utilized in teaching. The oscilloscope is implemented with FPGA and LabVIEW technique, and can communicate with the access power from PC using USB interface. We present the system architecture and the detailed hardware and software implementation. Test results demonstrate the excellent performance of the designed oscilloscope, and indicate that it could meet the requirement of most of experimental teachings on electronic information engineering. Teaching practices in integrated designed experiment and innovative practice project show that the quality of teaching improves signifi- candy with the utilization of the virtual oscilloscope.
