【Abstract】 An ultrasonic testing system with high speed data acquisition and transfer was developed. At least 100MHz high speed A/D technique was used in real time data acquisition system. The PCI(programmable communications interface) real time transfer mode solved the problem of data storage and transfer of large capacity. The key apparatus FPGA(field programmable gate array) and PLD(programmable logic device) adopted could meet the needs of development and research, which could keep secret and reduce the volume of the system.更多还原
