摘 要
本文设计了一种基于LabVIEW 的任意波形发生器,其功能是可以产生频率、幅值、相位、电压偏置等参数可以设置的正弦波、三角波、方波,锯齿波,还可以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盘,并能将其重新读出生成对应的波形。与传统仪器相比,虚拟仪器具有高效、开放、易用灵活、功能强大、性价比高、可操作性好等明显优点。

Abstract
One kind the main body of a book has been designed is LabVIEW-based arbitrarily wave form generator, whose function is to be able to produce frequency , amplitude , parameters such as phase , voltage polarization can sine wave, triangle interposing wave , square wave , sawdust wave, can generate two roads drawing by hand arbitrarily wave form, two road wave form data also may present be generated store a set , can the person be read again being born becoming corresponding wave form and. Compared with tradition instrument, the suppositional instrument has obvious merit such as high-effect , opening to the outside world , easy to use nimble , powerful, and a high nature price.
Key words:Labview ,Virtual instrument, Arbitrary wave generator
