I am looking to do some detailed analysis of my recorded data. I have been trying to look at the data in GNURadio using the FFT Plot, but I am having a hard time discerning things. Specifically, I am trying to see if a signal persists over a period of time. I am going to try and look at things with the Waterfall, but I am not sure that will be much better.
I am open to using another tool, such as Octave, if need be.
Any ideas?
Thank you.
