中文摘要：

随着计算机网络技术的飞速发展，远程测量系统得到越来越多的应用。为了更便于使用频谱仪、时间间隔计数器、时间间隔分析仪等测量仪器，以时间间隔计数器SR620为例，基于虚拟仪器LabWindows／cw开发平台，设计并实现了一种实时远程时间频率测量系统。该基于SR620的远程时间频率时间测量系统能对仪器状态实时远程控制与监视，并能获取、存储测量数据，并利用虚拟仪器的优势实时图形化显示测量数据变化趋势，具有较高的实际应用价值。

英文摘要：

The remote measurement systems have been used more and more extensively along with the rapid development of computer-network technology. In order to use the measurement instruments such as spectrum analyzer, time interval counter and time interval analyzers more conveniently, taking the time interval counter SR620 as an example, we designed and realized a real-time remote time-frequent measurement system based on the platform of virtual instrument LabWindows/CVI. The remote time-frequent measurement system based on SR620 can remotely monitor and control the instruments in real time, acquire and store the measured data, and a real-time graphical display of the measured data trend is also achieved with the virtual instrument＇s advantage. The system is of higher practical value.
