摘要
示波器在测控领域作用十分重要,并且结合计算机强大的计算能力能更好的对测试数据进行分析。针对示波器与计算机结合应用于测量领域的背景,研究了基于LabVIEW的示波器与计算机的USB通信和实现方法,以及LabVIEW连接数据库的实例,设计并实现了示波器多通道数据实时采集及存储系统。经测试,计算机可利用该系统获得正确而完整的被测信号波形,并且存储性能稳定。同时该系统可以将示波器探头接入不同的数据源,以采集测量所需数据,因此能够应用于不同的测试场景中,具有一定的通用性。
The oscilloscope plays an important role in the field of measurement and control,which can analyze the test data more effectively with the help of computer′s powerful computing capabilities.Under the background of the integration application measurement field with oscillograph and computer,a USB communication and implementation methods of the oscilloscope and the computer based on LabVIEW is studied,also with the connection example of LabVIEW and database,and an oscilloscope multi-channel data real-time acquisition and storage system is designed and implemented.After testing,the computer can obtain a correct and complete measured signal waveform using this system,and the storage performance is stable.Meanwhilethe system design can collect the required data for measurement through oscilloscope probe access to different data sources,therefor it can be applied to different test scenarios and has certain versatility.
