摘要
根据超短波接收机的数传要求,提出基于 PXI 的数传总线结构,详细分析了 PXI 总线协议,并讨论了其实现方法,给出了相应的硬件和软件实现方案,最后利用测试板对 PXI 数传总线进行了测试。试验结果表明,基于 PXI 的数传总线完全能够满足超短波接收机的数传性能要求。
According to the data transmission specifications of VHF/UHF receiver, the paper proposes the PXI data transmission bus architecture. The PXI bus protocol is thoroughly analyzed and a discussion is made on the methodology of realization. Meanwhile, the author provides a hardware and software solution accordingly and the test results on the PXI data transmission bus using a prototype. The test results proved that the data transmission bus based on PXI can sufficiendy meet the needs of data transmission of VHF/UHF receiver.
