| Abstract: | To achieve non-linear dielectric test, ADLINK DAQ-2005 data acquisition adapter is used to construct virtual signal generator and data processing system based on LabVIEW platform. The system realizes signal generating, data acquisition, signal filtering and response current decomposing. Firstly the overall block diagram of system is presented. Secondly the hardware selection and detailed software design are introduced. Finally the measured data and signal processed results are given. This design based on virtual instruments has important practical significance on non-linear dielectric measurement field. |
