Design and research of virtual instrument development board

Abstract

At present, the technology of virtual instrument has been developed very quickly in the field of electronic measurement and automatic control. The virtual instrument is a kind of functional instrument combining of software and hardware .This article is from the perspective of exploration and research, and as a reference when encounter hardware problems in the research and development of virtual instrument. Virtual Instrument Development board, based on LabVIEW development platform, can achieve virtual oscilloscope, virtual signal generator, virtual spectrum analyzer and so on. And the use of virtual reality on the oscilloscope signal testing and analysis, while the virtual signal generator's output signal also had a measured and analysis, the results are satisfactory, the virtual spectrum analyzer at the request of the software is relatively high, in this paper did not achieve this feature, but the hardware has been tested successfully. © 2011 Springer-Verlag Berlin Heidelberg.
