摘要
Abstract
As the traditional oscilloscope is more expensive and it is difficult to preserve data for a long time,the design of dual -channel oscilloscope, which is based on LabVIEW and FPGA, is proposed. By way of signal attenuation and the AD9288 analog-digital conversion, the Cyeione series FPGA is adopted as its core to collect value of dual-channel inputting signal. Through the computer parallel port,the dynamic link library is invoked to the corresponding driver to achieve the communication between acquisition board and PC. Through the virtual oscilloscope based on LabVIEW, waveform curve can be collected by real-time program-controlled display, which reads the history of the acquired waveform. The system is user-defined on design parameters. A single - chip in the system, lest range from - 20 to + 20V, which runs stably, is used to fulfill the main logic function and the interface is use - friendly.关键词
