Abstract: With the rapid development of computer technology and virtual instrument technology, virtual instrument is being regarded as the developing trend for the development of measuring field. The data acquisition system has been built based on LabVIEW and data acquisition module of PC/104 bus standard. The programming of the DLL for Diamond-MM-16-AT is discussed in detail and a program driving Diamond-MM-16-AT to accomplish data acquisition using CLF in LabVIEW is developed. The system is proved to work well to accomplish high speed data acquisition and real-time graph display by test.
