To meet the needs of the digital direction finding receiver for high-speed data acquisition and processing,developed a high-speed data acquisition and processing platform. The platform based ADC12D1800RF implemented two-channel band-pass IF signal sampling. Xilinx's V7 series FPGA as data processor,high-speed DDR3 memory device solves the problem of mass data storage,and high-speed serial interface (GTX / SRIO) enables real-time transmission of large volumes of data. The test results indicated the ENOB of this platform is greater than 8bits when at 1.8 GHz sampling rate,DDR3 operating frequency up to 1333MHz,GTX interface when working at 10Gbps rates,the bit error rate of less than 10-9. The above test results show that the platform can implement high-speed,accurate signal acquisition,data transmission,storage and processing,to achieve the desired design goals.
