Description: LabVIEW-based virtual oscilloscope design and detailed report, including VI design objectives and tasks: one, to master the use of A/D conversion and computer resources oscilloscope design methods. 2, the design of virtual oscilloscope. 3, the establishment of NI-DAQmx simulated devices, select E series NI PCI-6071E data acquisition card emulation module, through DAQmx physical channel identification, generates an analog signal, and then virtual oscilloscope based on LabVIEW development platform. The basic instrument can achieve performance and reliability, can easily be programmed to realize the data acquisition, real-time display, digital filtering, chopping display, waveform storage, echo waveform functions, spectrum analysis.
