You *may* be seeing an artifact of the truncation of the ADC samples.
Johnathan, others:
I believe this is not the case. When I download 16 bit samples from the
USRP and remove the 4LSBs myself, the spectrum looks normal. When I ask
the USRP for 8 bit samples, the spectrum shows a 1MHz wide sinc lobe.
Since it turns out the bottleneck for me is writing to the hard drive,
I'm happy removing the LSBs on the PC for now, but I'd love to hear your
ideas!
BTW, I'm using the 3.1.1 release and am downloading data to my hard
drive using my own c++ software linked against libusrp. I'll try this
with cfile to be sure it's not me.
