Joe,
Complex sampling does not require the sample rate to be 2x the highest
frequency as is the case for real sampling. It only needs to be 1x. So,
the 250MS/s sampling rate produces 250MHz of spectrum. But, there are
anti-aliasing filters that reduce this to a usable bandwidth of 200Mhz.

Hello,
I am currently looking to see what the highest possible sampling rate is for
the ettus N321/N320. I see that the highest master clock rate is 250e6 Mhz,
However, on the product website(https://www.ettus.com/all-products/usrp-n321/),
it says that it can collect up to an instantaneous

Just to answer my own question:
Run uhd_usrp_probe with LD_PRELOAD=/usr/lib/librfnoc-module.so uhd_usrp_probe
and it will be able to find the RFNOC modules.
The same for any test programs you use, those need the LD_PRELOAD as well.

Hi,
I've created a custom RFNOC module with two blocks, and have it installed.
The module.yml files are in /usr/share/uhd/rfnoc/blocks, I have a library for
it installed in /usr/lib (and VHDL files as well somewhere).
When I run uhd_usrp_probe I see the following:
[INFO] [UHD] linux; GNU C++
