| Abstract: | To meet the demand of data acquisition modules that are used in airborne testing, a design scheme of high-performance and multi-channel data acquisition module based on PXI bus and DSP are introduced in this paper. In this project, analog signal conditioning, data acquisition and processing are implemented on a single card. Furthermore, high precision synchronization-triggering of multi-card was achieved. This system has already been successfully implemented in airborne testing. |
