摘　　要：扫频仪是测量网络传输特性的仪器,在现代电子测量中占据着重要的地位,以LabVIEW为开发平台的扫频仪具有组建时间短、功能易于扩展与维护和开发费用低等优点。在此,介绍基于队列的多状态传递状态机,并以此为架构构建扫频仪系统,实现多通道数据的实时采集、数据传递、数据分析与显示等功能,然后在NI数采设备上实测了扫频仪性能,最后总结了基于队列状态机的完成扫频功能系统的优势。Frequency sweeper system based on LabVIEW has advantages of short design period,easily extended function,low cost and so on.Multi-state transmission state machine based on queue is introduced,and a frequency sweeper is build on this architecture in the NI DAQ instrument,achieving the function of multi-channel real-time data acquisition,data transmission, data analysis and display.Finally,the advantages of frequency sweeper based on queued state machine are summarized.
