摘要
对PXI总线下实现高速数据采集以及信号同步进行了探讨和研究,并对PXI总线下星形触发作了阐述,利用PXI总线的时钟同步功能和信号的特殊性提出了解决问题的方法。通过PXI总线高速采集系统的实现,得到了多板卡星形触发方式下时钟的不绝对同步结论。
It is the discussion & research for realizing high-speed data acquisition & signals synchronizing based on PXI Bus. It also expatiates the Star Triggering based on PXI bus. The problem is resolved by the particularity of signals. Multi-cards' imprecise synchronization under star triggering is validated by realizing high-speed data acquisition based on PXI Bus.
