中文摘要：

存储深度表征了示波器在最高实时采样率下连续采集并存储采样点的能力。提高存储深度有助于提高系统分析波形细节的能力,但同时也会导致系统响应速度的下降。基于超高速并行采样和波形快速定位与缩放等技术,设计了实时采样率高达6 Gs/s,存储深度高达512 Mpts的高速深存储数据采集系统,重点提出了一种深度存储条件下的波形快速定位与缩放技术,以解决提高深度存储所带来的响应速度慢、波形捕获率低等问题。最后给出信号实时数据采集的实验结果。结果表明运用波形快速定位与缩放技术,系统响应速度大幅提高,可以快速定位并显示用户所关心的波形细节,提高示波器的性能。

英文摘要：

Memory depth characterizes the capacity that oscilloscope continuously acquires and stores sampling points at the highest real-time sampling rate.Increasing storage depth will improve the ability of analyzing the details of waveform,but also lead to decline system response speed.Based on parallel sampling technology,this paper proposes a ultra-high-speed and deep-storage data acquisition system,which has a real-time sampling rate up to 6 Gs/s and storage capacity of 512 Mpts,and introduces a technology for rapid waveform positioning and zooming,which can solve the problem of slow response speed and low waveform capture rate resulted from increasing storage depth.Finally,experimental results show that using the technology of rapid waveform positioning and zooming can significantly improve system response speed,quickly locate and display the details of waveform that users concern,and enhance the performance of oscilloscope.
