摘　　要：本文利用LabWindows/CVI开发动态信号分析仪器(Agilent 35670A)控制软件时,通过多线程读取动态信号分析仪寄存器中的数据,并按试验需求将这些数据实时显示在用户界面上。避免了软件多任务间的冲突,解决了软件在读取仪器数据实时显示时的卡死现象,体现了线程实现实时多任务方面的有效性,很好的满足了软件需求。The dynamic signal analysis instrument(Agilent 35670A)control software was developed by using LabWindows/CVI.The multithreading test data in dynamic signal analysis instrument ROM were read,and the data on the user interface in real time as test requirements were displayed.It avoided software multitask conflict,and solved software crash during reading instrument data real-time display.The software is expressive of multithreading effectiveness in real-time multitask and meets the software requirement.
