摘　　要：介绍了一种PC插卡式高速、大记录容量数据采集卡。提出了双ADC交替采样实现100MSPS的采样率的方案。并针对设计中需要解决的交替时钟的产生，大容量、高速缓存电路的实现等技术要点加以讨论。A PC plug-in data acquisition card is described with a sample rate up to 100 MSPS and 1 MByte on board storage in this paper. The method using two ADC driven alternataly by two complementary 50 MHz clock to form a 100MSPS sample rate is introduced. Some techniques such as how to get the two complementary clock, how to design the high speed and large storage circuit are also discussed in detail.
