Design of Programmable Function Generator Based on LabVIEW

A programmable function generator based on LabVIEW is introduced.With graphical programming method of LabVIEW,the function generator 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 generate two roads arbitrarily waveform drawing by hand.Two roads of current generated waveform data is stored into the computer,the data is also read again being born becoming corresponding waveform.Compared with traditional instrument,the function generator designed 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.
