摘要
介绍了频谱分析仪中本振自动扫描的几种常用工作方式,给出了利用DDS来实现本振自动扫描的原理方法。论述了在实际工程中如何应用FPGA设计来实现本振的自动扫描,并给出了设计主要指标结果。
This article mainly introduces a few of method of general LO sweep in spectrum analyzer, Products the principle of realizing LO sweep by using of DDS. Discussing how realizes LO auto-sweep with FPGA in project .Also, we give the experiment result in various pattern of LO sweep.
