摘要: 设计了一种基于PXI-1031高速同步数据采集卡(DAQ)的虚拟仪器硬件测试系统。利用Labview8.5程序设计出了测试系统所需的数据采集和数据处理分析程序。使用Fluke-282任意波形发生器产生两路频率分别为150Hz和270Hz的正弦信号,应用数据处理分析程序完成了两路信号的互功率谱密度计算。仿真试验结果表明,测试系统达到了设计要求。

Abstract: This paper designs a measurement system based on PXI-1031 high-speed synchronization DAQ. By using Labview8.5 program, the data acquisition and data process and analysis program required by the measurement system is designed. By using Fluke-282 arbitrary waveform generator, two passages of sine signals with 150Hz and 270Hz are produced. By using the data acquisition and data process and analysis program, the cross power spectrum density is calculated for two passages of sine signals. The simulation test results show that the measurement system can meet the design requirement.
