| Abstract: | Present a microcomputer-based ultra high speed data acquisition and analysis system. Some advanced techniques such as flash ADC, software virtual panel, high speed graphic environment and PC-based instrument design are used in the overall layout. A 32MSa/s storage digital oscilloscope with four analog inputs has been successfully realized. High sampling rate is obtained by using high speed technique flash ADC, time-shared and memory-partitioned technique.The main structure of the hardware and the software is presented. Some anti-noise measures are also discussed. |
