Before we go down the rabbit hole of debugging, why are you doing this? Is
this to enable the simulator?

With an FMCW radar and a matched filter, the leakage signal will be at a
different range (close to zero range) than the targets. So, you could just
ignore this range region of your results. But, if the leakage signal is
strong enough to either saturate the A/D or to cause the corresponding
range
OK, some random thoughts:
- Can you verify that you have /share/uhd/modules.d/rfnoc-vastech
and it contains a valid DLL name (like libvastech.so)?
- (FYI: That's how the simple program finds the module)
- Are you sure that the make() call triggers the registration? How are you
confirming that?
-
See here for instructions on how to update the filesystem on the device to
the one that matches your UHD version.

For an ADC, I believe the noise power is fairly constant. As sample rate
increases, noise power density should decrease and SNR should improve. Thus
a measured improvement in noise figure.

Using UHD 4.6/Ubuntu 22.04/x310, I have built many images in the last year
or so with rfnoc_image_builder. Recently in the last month, I get the
following error on almost all images:

I have tried the following, after referencing this the known issues section
in the USRP3 build
