Honored ContributorFFT Frequency Range
I am using the 50MHz internal clock of the Stratix III to collect samples of a chirp signal operating at 30kHz to 80kHz. I read in one of the forums that the FFT MegaCore output frequencies are 0~Fs...

Honored ContributorUnfortunately yes. You are in a situation when you have upsampled the signal
very high then you need to downsample back if you want that KHz of fft resolution. Try if you can apply lower sampling rate to your ADC level as it is way too high.
