单板、单片高速数据采集系统研究与设计
|
摘要
随着科技的发展，数字存储示波器作为常用的检测工
具，将取代模拟示波器。其广泛应用，为该类仪器的国产
化提出了紧迫的要求。本课题研究将数字存储示波器的核
心部件—采集与控制电路集于一体，模块化，以便应用于
通用便携式数字存储示波器。其中，单片采集控制电路采
用FPGA实现，并给出了仿真结果。还讨论了随机采样电
路、信号调理电路、A/D变换电路的设计，总结了实际工
作中遇到的一些问题和解决办法。
With the development of science and technology, the Digital
Storage Oscilloscope, as a common instrument, will replace
Analog Oscilloscope. At the mean time, the growing domestic
requirement of DSO has urged researching tasks in this area.
The single board, single chip data acquisition system, which is
the core of DSO, tries to assemble the control circuits of data
acquisition circuits into a single FPGA chip to make it suitable
for portable DSOs. In this article we also discuss the design of
random acquisition circuit, signal condition circuit, A/D circuit
and so on. In each digital circuit, the simulating results are
given. At end of the paper, some problems, which are
encountered in designing, debugging, simulating process, are
presented and the solutions to them are given.
