摘　　要：介绍了在合肥光源重大维修改造工程期间,开发的一套基于扫频激励法的工作点测量系统。测量系统硬件包括基于条带BPM的信号拾取电极、前端信号调理模块、一台带跟踪输出的信号分析仪N9000AEP、功率放大器以及用于激励束流的条带激励器。系统控制软件采用EPICS开发,基于EPICS Stream Device设计的输入输出控制器(soft IOC)运行在服务器虚拟机中,通过VXI11协议进行通信实现对信号分析仪的控制和数据获取;用户操作界面采用EPICS平台下的EDM开发,通过Channel Access与IOC通信。在HLS-II储存环上对工作点测量系统进行了在线的调试。调试结果说明,在扫频范围为2.1MHz到4.1 MHz时,工作点测量系统的统计分辨率在水平方向上好于0.000 3,在垂直方向上好于0.000 2。In the HLS-Ⅱstorage ring,a swept-frequency excitation（SFE）based tune measurement system has been developed and running well.This paper presents the construction and commissioning of the SFE-based tune measurement system.The system hardware includes spectrum analyzer with tracking,excitation module,strip-line kicker,signal processing module and beam position monitor（BPM）as signal pickup.The control software of the tune measurement system is developed using EPICS software.The control software consists of three parts：input/output controller,operation personal interface and channel access.The on-line test of the system is performed to investigate the system statistical resolutions in the two transverse directions.Test results reveal that the statistical resolutions are better than 0.0003/0.000 2in the swept range from 2.1 MHz to 4.1 MHz.
