虚拟示波器通信实现任意时间间隔测量

Use Virtual Oscilloscope Communications to Measure Time Interval

介绍了示波器在远程通信状态下,利用其Δt功能,实现对任意时间间隔的任意波形进行测量的方法,即利用虚拟面板调节,使计算机通过GPIB接口卡、GPIB总线至被控示波器,实现对Δt标记光标的移动控制,从而达到对时间间隔的测量目的。此方法简单实用,提高了测试系统的自动化程度,给使用者带来极大方便,具有广泛的借鉴价值。

Method of measuring arbitrary time interval of arbitrary waveform in state of remote communications of oscilloscope taking use of its At function is introduced. That is, by adjusting in virtual panel, computer can control motion of At cursor in oscilloscope under control through GPIB card, GPIB bus to achieve the aim of measuring time interval.
