AbstractThe 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 instruments advantage. The system is of higher practical value.

Key words: time interval; remote monitor; real time; virtual instrument
