摘要
提出了一种基于PXIE总线的频谱监测设备设计方法,弥补了传统频谱监测数据交互能力的不足,可显著提高频谱监测与分析性能。该方法基于硬件平台标准化和软件模块化的设计思想,优化设计了快速频率扫描流程和高性能数字中频处理方案,使设备具有较强的频谱分析能力和良好的扩展性能。实例应用效果表明,新设备不仅瞬时分析带宽高、扫描速度快,而且可进行灵活的功能扩展,可满足不同场合下的频谱监测任务需求,具有广泛的工程应用价值。
A spectrum-monitoring-equipment design based on PXIE bus is proposed,thus to make up the inadequacy of data throughput for traditional spectrum monitoring equipment,and significantly improve the performance of spectrum monitoring and analysis. This method, based on the idea of hardware platform standardization and software modularization, optimizes the scheme of fast frequency scanning process and high-performance digital IF processing, thus making the device possess strong spectrum analysis capability and good scalability. The experiment indicates that the new device has high instantaneous analysis bandwidth and fast scanning speed, and in addition, can flexibly extend its function,and thus can meet the needs of spectrum monitoring tasks under different occasions, and is of extensive engineering application value.
