用计算机实现对频谱分析仪和信号发生器的数据采集和波形显示

问题:信号发生器发出信号后经过被测器件,输入频谱分析仪。把信号发生器和频谱分析仪与计算机连接,用LABVIEW实现对波形的显示和比较。

本人初学,希望哪位大侠给与指点,不胜感激。最好有个例程,谢谢啦

Hi,

 

First of all, it is going to be "not a simple" coding, even if not huge and complex one...

 

What you need, first, is the LabVIEW Instrument Drivers for your devices. You may try searching them at NI's IDNET.

 

Next, you need to know how the tasks are done manually. From there, you will perform the "equivalent" function calls in your LabVIEW program code to obtain the expected result/ data.

 

Then, you can use analysis functions to do the rest of the comparison etc.

 

Try also searching for examples with the LabVIEW example finder.

谢谢您,其实我还是不知道在LABVIEW上怎么实现与实际中一样的功能。不过依然十分感激!

Basically, once you had the instrument's LabVIEW drivers installed, you will see them in the Instruments I/O library in functions palette.

Browse through those functions, and you will know how to use them 🙂
