信号发生器是许多电子设备特别是测试设备必备的一部分，用以输入基准源信号给被测设备，通过接收被测设备返回的信息分析研究被检测设备的情况。传统的信号发生器主要靠硬件来实现，其功能单一，维护费用高，这里研究的虚拟信号发生器基于虚拟仪器技术实现。该虚拟信号发生器不但界面友好，而且功能强大、操作简便，而且可以进行频谱分析。经仿真实验表明，它能够产生实验室常用的正弦波、三角波、方波、锯齿波等波形，频率范围较宽，相关参数可调。

Signal generator is a necessary part of many electronic equipments,especially the testing equipments. It is adop-ted to transmit the reference signal to the UUT,whose status is judged according the returned information of the signal. Imple-mentation of the traditional signal generators mainly relies on hardwares. Their functions are single,but maintenance cost is high. The virtual signal generator researched in this paper is based on virtual instrument technology. It has a friendly inter-face,powerful functions and simple operation,and can make spectrum analysis. The simulation results show that it can generate sine waveform,triangle waveform,square waveform and sawtooth waveform,which are usually used in laboratories. It has wide frequency range,and its relevant parameters are adjustable.
