Hello, I don't know if this is intended behavior or not.
I am running ./usrp_siggen -f10e6 -w150k -i256 At the receiver, I am running ./usrp_fft.py with -f9.8e6, -d128 I see a peak at -150k. According to my calculations, (10e6 + 150k) - 9.8e6 = 350k. This is outside the Nyquist interval (-250k, 250k). Thus it gets aliased: 350k - 500k = -150k. Which seems to explain the peak. However, is this intended behavior? The magnitude (20dB) of the peak is smaller than usual, compared to when I set center freq to 10e6 (>45dB). I am uncertain.
