摘要
本文介绍了基于ＶＸＩ总线基本硬件和图形化编程语言ＨＰＶＥＥ设计的一种虚拟信号分析仪器。文中详细阐述了该仪器的设计思路和设计方法，以及仪器的功能特点。该虚拟仪器硬件配置简单，汉化软面板界面友好，不仅实现了一台信号分析仪器的功能，而且还可以实现对信号的频率、周期、脉宽、上升和下降时间的测量。
The paper introduces a kind of virtual signal analysis instrument which is based on VXIbus hardware and graphical programming language HPVEE. The procedure and the method of designing the virtual instrument are specified,and the function of the instrument are presented in detail. The hardware is configured simply and the Chinese soft panel is friendly. The virtual instrument not only has the function of a signal analysis instrument, but also can realize the measurement of signal's frequency, period, pulse width, rise time and fall time.
