根据汽车点火系统性能在线测试设备的速度要求和被测信号的特点,提出了运用高速ADC、高速RAM及触发通道设计数据采集系统结构的方法。
Through the utilization of the characteristics of the tested signals and the required speed of the testing equipment of on line of automobile ignition system, a method for desiging a highspeed data acquisition system is presented. The system includes a flash A/D conventer, a data buffer memory and a trigger channel, which can be widely used in the acquisition and processing of twinkling signals, periodic signals and non periodic signals.
