摘　　要：设计了一种基于LabVIEW的可编程函数发生器,借助LabVIEW图形化的编程方式,可以使函数发生器产生频率、幅值、相位、电压偏置等参数可设置的正弦波、三角波、方波、锯齿波,还可生成两路手工绘制的任意波形。也可将当前生成的两路波形数据存储,并将其重新读出生成对应的波形。与传统台式仪器相比,该设计的函数发生器具有高效、开放、易用灵活、功能强大、性价比高、可操作性好等明显优点,可以应用在许多领域。A programmable function generator based on LabVIEW is introduced. With graphical programming method of LabVIEW ,the function gen- erator is able to produce the sine wave, triangle wave, square wave and sawtooth wave, whose frequency, amplitude, phase and voltage bias parameters can be set, and can genet：ate two roads arbitrarily waveform drawing by hand. Two roads of current generated waveform data is stored into the com- puter,the data is also read again being born becoming corresponding waveform. Compared with traditional instrument, the function generator de- signed by the paper has obvious merit such as high-effect, opening to the outside world, easy to use nimble, powerful, and a high nature price and can be used in many fields.
