摘　　要：针对远离实验室使用的电子仪器仪表难于开展现场故障测试的问题,设计了一种便携式虚拟示波器。文章从系统构造,软、硬件设计等方面介绍了虚拟示波器的实现,重点阐述参数配置、数据采集、数据显示等关键技术。仪器基于虚拟仪器技术,利用NI公司高速数字化仪USB-5133及LabVIEW应用开发环境,可实现双通道信号的同步测量与分析,与PC机的连接方式采用灵活方便的USB串口方式,是一台便携实用的示波器。A portable virtual oscilloscope is designed for solving the problem of on-site fault testing difficulty when it away from the lab for the use of electronic instrument. This paper introduce the realization of the virtual oscilloscope, including the system structure, software and hardware design. Parameters configuration, data acquisition, data display and other key technologies are expounded. The instrument based on virtual instrument, with a high-speed digitizer NI USB-5133 and the LabVIEW application development environment, dual-channel signal synchronous measurement and analysis can be achieved. This is a practical portable oscilloscope, it can be connected with the PC by flexible and convenient way of USB port.
