Aiming at series of problems of traditional digital oscilloscope,such as difficult signal analy-sis, weak data storage capacity, high cost and so on, a design scheme of virtual digital storage oscilloscope based on LabVIEW is proposed.The hardware system consists of four parts, namely, attenuation and gain control, A/D conversion, sampling control and data storage.The software system is constructed on the basis of LabVIEW platform which has friendly interface and easy operation.The virtual digital storage oscilloscope has functions of seven gear vertical sensitivities, eighteen scanning speeds, seven trigger modes chosen freely etc., which can realize signal acquisition, analysis, processing, display and so on.After three kinds of signal test, such as sine wave, square wave and triangle wave, the virtual digital storage oscilloscope has stable oper-ation, high reliability, good performance and certain application prospect.
