So you are looking at 1MHz of spectrum with a sample rate of 1Msps
complex centered at 1MHz coming in from the USRP? Or do you receive a
complex stream directly from the USRP at baseband?
I am looking from 1MHz to 2MHz, therefore i set up the frequency
in the Usrp to 1MHz and the samp_rate to 1Msps(1MHz Signa Bandwidth).
The CIC filter has roll off which could be your culprit? Do you have
a spectral plot of your bands as well as the entire incoming spectrum?
i will watching this next monday.
thanks and regards markus
