摘要
为解决基于PC104平台的超短波频谱监测接收机研制过程中的中频多速率数据采集问题,介绍一种模块化设计的多速率数据采集系统。主要阐述系统硬件结构、PCI9054本地端逻辑设计、WDM功能驱动程序设计以及性能测试等。实际测试证明,该多速率数据采集系统能够满足超短波频谱监测设备对中频数据采集系统的性能要求,接口部分数据传输速度快、采集部分配置灵活。
In order to solve the UHF multi-rate data acquisition issues in the development of UHF radio spectrum monitoring receiver based on the PC104 platform,describes a multi-rate data acquisition system using modular designing method.Mainly expounds the system hardware architecture,PCI9054 local-side logic design,WDM function driver design,and performance testing.Actual test proved that the very acquisition system which hold high data-transferring speed and sampling module flexible configuration method is suitable for the IF acquisition performance demands for the UHF radio spectrum monitoring device.
