摘要
介绍了一种基于FPGA和AD的低成本、高性价比的微型虚拟示波器设计,以8位高速AD转换器为模拟量采集单元,以高性能可编程逻辑器件FPGA为控制核心,运用分频步进取样,将采集到的波形数据送入PC机,实现了波形的显示,功能强大,具有较高的性价比。
The paper gives a description about how to design a kind of high performance-price ratio micro virtual oscillograph based on FPGA and AD.Its analog acquisition unit is an 8-bit high-speed AD and its control core is FPGA which is a high performance programmable logic device.Using dividing-frequency step-sampling,it can put collected waveform data into PC,realized the display of the waveform.h＇s very powerful and has high performance-price ratio.
