摘　　要：采用模块化的概念,在LABVIEW图形化虚拟仪器开发平台上实现虚拟任意波形发生器和示波器系统.本系统包括模拟信号发生模块,处理与分析模块,存储与读取模块以及显示模块.其中,测试对象由模拟信号发生模块产生,该模块主要由信号发生器和通道选择器组成.数据处理与分析模块由参数测量、滤波、频谱分析、波形运算构成.最后进行了系统测试,经测试可见,该虚拟示波器较为成功地实现了示波器的基本功能,实用性较强.A virtual arbitrary waveform generator and wave oscilloscope based on Lab-VIEW is designed in the paper. It includes four blocks.arbitrary waveform g6nerator, signal analyzing and processing, data col- lection and storage, and display module. The testing objects for the wave oscilloscope are produced by the virtual arbitrary waveform generator including waveform generator and channel selector. The signal analy- zing and processing block consists of parameter measurement, filtering, spectrum analysis and waveform calculating. Finally, the specification of the system is simulated and tested. The simulation results show reliability and practicability of this method.
