| Abstract: | To solve problems of dynamic, transitional and transient signal measurement, the chief techniques and design principles of a high speed, large scale data acquisition card based on PCI bus are discussed. The card consists of pre process circuit, A/D converter, on board memories, high speed clock generator and control circuit integrated in FPGA. It can achieve 8 bit resolution allowing up to 400 MHz sampling rate with 512 MB on board real time memory. |
