High-Speed Data Acquisition System Based on FPGA

This artie introduces a High-Speed Data Acquisition System Based On FPGA, discussed the principle and implementation method of high speed data acquiring,saving and transmitting. The system has two separate channels of 250 MS/s sampling rate. The system use high- performance FPGA to achieve channel controlling, data processing and connect to other circuits. It owns the high-power regulation circuit which can choose matched impedance and coupled modes. It can adjust gain automatically. This data acquisition card can be built to test system with other PXI instruments.
