摘要

在宽频带弱信号检测仪器中,为提高信号的采样精度和采样率,给出了基于TMS320VC5402和两片CS5397并行工作构成的24位双通道数据采集系统的软硬件设计方法,采样率可以达到192kHz。实验结果表明,通过采用双片CS5397并行采集模式,该系统可以对40kHz的正弦信号进行较好的波形恢复。
In order to detect wideband weak signals, a high precision data acquisition system with high sampling rate is often demanded. A software and hardware design method of Doublemodule data acquisition program is given. The system based on TMS320VC5402 is made of double 24bits ADCCS5397 and its samping rate is up to 192 kHz. The results of the test are given at the end of the paper. It proves that the data acquisition system can retrieve the waveform of the 40 kHz sine signal better by using two CS5397 working interleaving.
