摘要
针对采集系统存在参数可配置性低、不能够多通道独立预触发采集的问题,提出了参数总线传递和动态缓存分配方法,设计了具有动态参数配置和独立采集功能的存储测试系统,使其具有程控信号调理、采样参数可调、8路独立预触发等特性。试验验证了系统可靠有效,对信号采集系统的研究和应用具有一定实际意义。
In acquisition system,the configurability of parameter is low and are pre-trigger acquisition can not be achieved in multi-channel independently.A method of parameter bus transfer and dynamic cache allocation is proposed.And a storage test system with dynamic parameter configuration and independent acquisition function is designed.It realizes several new functions,including programmable signal conditioning,sampling parameters adjustable,8 independent pre-trigger.The simulations demonstrate our system is reliable and effective,and it is useful for the research and application of the signal acquisition system.
