Greetings to all!
I am a very new GNU Radio user.
For now I am trying to get simple example with spectrum analyzer.
I am encountering problems with understanding the result of the results
I get. I am attaching to screens - one for the schematic and one for Qt
FFT block result.
As for now I do not understand - why do I get some strange -15dB value
on spectrum for I am using a simple gen with 1 volt amplitude. And how
to customize the y-scale correctly.
I hope if anybody can help me with this and clarify those questions.
Thank everyone in advance.
Alex
