If you had a polyphase channelizer on the FPGA, that would be an efficient
solution to your problem, but there's no such block as part of UHD itself.
There have been channelizer blocks written in the wild, but that would be
something you'd have to figure out.

Also note that large signals on one channel will leak into the other
at baseband, I believe. I think it's just the nature of the 2-channel
design using the single ADC and everything being so close.
The datasheet for the ADC shows ca -88dB cross-talk b

Hi Olo,
On one point regarding an FFT length of 8192, there is likely an issue
with using the Ettus FFT block. In the past (I haven't checked
recently), this block was limited to a maximum FFT size of 1024
because the entire FFT had to fit
Hi Olo,
On one point regarding an FFT length of 8192, there is likely an issue with
using the Ettus FFT block. In the past (I haven't checked recently), this
block was limited to a maximum FFT size of 1024 because the entire FFT had
to fit in one packet where the maximum packet payload was about 20
10 matches
