| Abstract: | For the purpose of engineering testing, a USB-interfaced data sampling and frequency-spectra analysis methodology is proposed based on LabVIEW technology. By calling such a function node as UA3000.DLL, high-speed data sampling can accordingly completed. Meanwhile, frequency-spectra analysis is conducted via a sub-virtual-instrument in terms of digital signal processing. In this manner, the system comprises several modules, such as data sampling, frequency-spectra analysis, data demarcation, database recording and experimental reporting. |
