Wang Hui · Electrotechnics Electric · 2009
Introduction was made to the design process of oscilloscope based on virtual instrument platform.The bottom hardware circuit adopted fi eld programmable gate array as logic controller,the upper layer used LabVIEW software to develop application software on PC and communication was realized by USB.The oscilloscope could carry out two-channel display,reading waveforms' amplitude and storing them.It has good effects in functionality,manipulation and precision.
