| Abstract: | This article presents a scheme of narrowband IF(Intermediate Frequency) signals generator based on PCI bus under VxWorks,and its implementation as well.The real time processing is guaranteed by RTOS(Real Time Operation System) VxWorks and high-speed transmission performance of PCI local Bus.Moreover,high-quality IF signals are generated by DDS technology.Its application in radar simulation system shows that this implementation is effective. |
