I am not sure what you mean by high frequency. Is the bandwidth of your
signal 32Mhz or is your signal on a 32Mhz carrier?
Take a look at digital down conversion:

The fft sink shows you frequency components from -sample_rate/2 to
sample_rate/2. Thats it.

Hello!
My question is the followed: If I have a high frequency Signal ( for
example: 32MHz ) and if I want to see a FFT of this Signal, how can i
do? If I try with FFT sink, it's doesn't working beacause the sampling
frequency have to 2* higher to be. What is the solution?
