Spectogram similar to "Baudline" within LabView

[meeeeeeeeeee]

Hey folks,

I was wondering if LabView has a similar diagram to the spectogram diagram of the baudline Software (see attachment).

I tried it with the waterfall diagram but thats not really working for me. Any suggestions?

Thanks in advance!

Hi mee,

welcome to the forum!

Yes, LabVIEW has what you need:

- For the spectogram you can use an intensity graph. This one also supports cursors, which can be used to pick the "time of interest" as shown in your image.

- To present the single FFT in the lower part of your picture you use a waveform graph…

That is not a static intensity graph it is a "waterfall" display taht scrolls vertically.

Can an intensity graph scroll vertically like the "waterfall" in Baudline and SDR applications?

Hey,

thanks for the quick responses. Yes what I'm looking for should display the "history" like in a waterfall graph (see picture from RTSLVU).

Isn't that possible with the intensity graph? Sorry I'm quite new to Labview and it's on my work computer so I couldn't validate the answer yet (today was home office ;-)).

Hi RTSVLU and me,

an intensity graph just shows the content of the 2D array data wired to it (THINK DATAFLOW!): when you want to scroll vertically all you need to do is add columns instead of rows. Or use TransposeArray…
