PLease help me!

Hi everybody!

I'm indeed not an expert in Labview and I got one problem.
I need to make an FFT from a Spreadsheet-file with 2 to 4 channels and
show it on the display. The spreadsheet file is made with labview.
I hope that there is anywhere in de www an example like this, which I
can download. Little changes, I can do by myself, but I never coult
programm it totally...and need it immediately (the better yesterday :-))

Is there anybody who can help me????

glad to do it ... find attached sample

or post your VI ... it will be easier to see the problem

sorry, the answer was for another post ... my mistake

anyway, can you post your file with the data and any information about it ... maybe it will be easier for somebody to help you ...

Sorry for the previous post ... I mistakenly posted in your thread.
Anyway, now I am trying to help you solve the problem.
First place you can search for is NI site with "+fft +download" hoping that you can find a VI/LLB to do the job.
Also, it would be easier for us to help if you can give some more details about input data and how do you want to handle the result.

Good Luck!

Doesn't matter 🙂

Fine.

Well, I got a Spreatsheet-File from LabView with 4 Channels and
2000Samples/sec.
Now I need to know wich frequences are present how strong in this time in
my signal.
So I would like to get as a result a diagram with the power on the y-axis
and the frequence on the x-axis.
My NI-Instrument is the AT-MIO-16E-10 DAQ-Card, if you need this
information too.

Thanks also for your hint with den NI-page, I'll see, what I can found...

cu, nice weekend

Hi Gerd,
find attachment ... may be a starting point for you. I did them following your requirements but I am far from being an expert with FFT.
Let me know if you need help.
