核磁共振谱仪技术中的高速数据采集

APPLICATION OF FPGA TECHNOLOGY IN HIGH SPEED DATA SAMPLING

采用Burr Brown公司的 1 0MHz、1 2BitA/D采样器件设计了一块基于PC总线的高速A/D采集卡 ,给出了核磁共振实验结果 。

The present article employs a piece of ADS804 (Burr Brown, USA) Integrated Circuit to design a high speed Analog to Digital Conversion card, which is based on the ISA bus of the popular personal computer. Nuclear magnetic resonance spectra obtained with the ADC are given. The application of high-speed ADC to the simplified design of the NMR spectrometer is also discussed.
