The emergence of virtual instrument technology into human testing a new era of development. Digital oscilloscope is often used in scientific research and laboratory a kind of desktop devices, of complex processing of such equipment is very expensive. Virtual oscilloscope an electronic measuring technology and computer technology, deep integration, has good prospects for development of a new class of electronic devices. Just configure a virtual oscilloscope with the necessary technical data acquisition hardware, the functions of the oscilloscope can be achieved, under the building for low-cost data acquisition system provides a new method. NI LABVIEW application provided with computer modular programming method, the virtual oscilloscope software. LABVIEW-based virtual oscilloscope design, hardware system uses 51 And A / D converter for data acquisition, and full use of the PROTUES and KEIL combination of simulation capabilities, hardware and software systems for simulation debugging. LABVIEW-based design and implementation of the virtual oscilloscope oscilloscope both the traditional graphical display, but also has simple, user-friendly, stable and reliable performance and lower cost. Implemented in LABVIEW environment and reality similar to the actual function of the osc
