提出了一种可完成２５０ＭＳ／ｓ，８ｂｉｔ模效转换的超高速数据采集系统．系统采用了分路数据输出的体系结构、微波传输线的连接方式以及多种抗干扰设计，使系统在２５０ＭＳ／ｓ，１２５ＭＨｚ信号输入时仍能保持７ｂｉｔ左右的有效位数．
A super high speed data acquisition system which can finish 250MS / s, 8bit mode conversion is proposed. The system adopts the architecture of shunt data output, the connection mode of microwave transmission line and a variety of anti-interference design so that the system can still maintain the effective number of bits about 7bit when the signal is input at 250MS / s and 125MHz.
