FFT save and display

[deepak23]

Hi,

Am new to labview and am just getting the hang of it. My main application is to acquire data and carry out FFT on it and store the FFT for subseuent review/ analysis.

I would like to store multiple FFTs and display it as a waterfall chart. Is it posible to show multiple FFT spectrums on a single waterfall chart.

Is it also possible to store and retrieve such spectrums.

(The spectrum generation will be a triggered event, either timed or operator triggered.)

Thanks

Deepak

Hello,

I'm not sure what version you're using, but I have attached binary file writer and reader examples in 8.0 which can serve as a model for storing your and retrieving your data - the writer example writes a 2D array to file, and the reader reads the file and displays the data - the file written by default is a file called test.bin on your C drive.

As for the waterfall chart, you'll find an example in the following thread (see the last post) which implements a waterfall plot using an XY Graph:

I hope this helps!
