摘要
以Altera公司的现场可编程逻辑器件EP1C6Q240C8和多通道高精度模数转换器AD7934为例,设计实际的FPGA+A/D数据采集硬件平台。通过分析AD7934的读写时序关系,借助Verilog HDL语言编写采集程序,在QuartusⅡ平台上利用SignalTapⅡ逻辑分析仪抓取数据,然后导入MATLAB分析处理,进行数据的验证。实验结果表明,硬件方案合理,软件设计得当,达到了预期结果。该设计方案已在某专用频谱监测设备中成功应用,可为监测、测向和定位接收机的数字处理模块提供设计参考。
Firstly,an actual hardware based on FPGA＋A/D is designed according to the datasheet of AD7934 and EP1C6Q240C8.Then,a program to control data acquiring is presented in detail.Finally,a verifying experiment is done with SignalTapⅡ Logic analyzer and MATLAB.The results of the test show that,the design of the hardware circuit and the software control is reasonable and reliable.This design has been applied into special spectrum sensing device successfully.Moreover,it provides a reference for digital processing module of monitoring,finding and locating of wireless signal.
