Arbitrary waveform generator based on LabVIEW and SOPC

研究了基于LabVIEW和SOPC技术的任意波形发生器的设计与实现方法,阐述了该系统的工作原理,介绍了上位机软件的设计、信号发生模块的设计及后级模拟电路的设计,最后给出了该任意波形发生器的测试结果。结果表明该信号源可以方便的实现任意波形的输出,具有波形质量好,频率输出稳定,输出频率范围宽等优点,在实际中有很高的应用价值。采用LabVIEW和SOPC结合的方案,充分利用了LabVIEW的可视化设计以及FPGA的可编程性,使得整个系统具有集成度高、操作性好、升级方便等优点。

The paper studies the design and implementation of arbitrary waveform generator based on LabVIEW and SOPC technology,illustrates the overall design for the system,introduces the design of PC software,signal generator and analog circles and presents the test results of the signal generator at the end.The results indicated that it can fulfill the arbitrary waveform freely,has the virtue of better waveform,stable frequency and wideband,has better application value in real life.Adopting combined LabVIEW with SOPC technology plan can make use of the visual design of LabVIEW and the programmabirity of FPGAs,making the whole system high integration,good operability,and easy to update.
