摘要
常温下FC D515探测器的读出时间在30 μs以内,为其设计了一套数据获取系统.并且详细介绍了组成该系统的数采、驱动、控制三个板卡的具体功能与电路设计.通过一个模拟脉冲星的实验对400 kHz和100 kHz两种驱动频率下的数据获取系统作了分析比较,表明系统周期搜索的精度在10-2ns数量级,而且400 kHz比100 kHz能提高7%的精度.且具有良好的短期和长期稳定性.
The reading time of the FCD515 detector is less than 30μs at room temperature. This paper designs a data acquisition system. The detailed functions and circuit design of the three boards for data acquisition, drive and control of the system are introduced in detail. Through an experiment of simulating pulsars, the data acquisition systems at 400 kHz and 100 kHz drive frequencies are analyzed and compared, which shows that the system cycle search error is on the order of 10 2 ns, and 400 kHz can improve the accuracy by 7% compared with 100 kHz. This system also has good short-term and long-term stability.
