Hi Derek,
Thanks for answering my question. That is good to hear, but does this
not apply to the BasicRx?
When I try to use the subdevice spec "A:A A:B" (i.e. to use the same
sampling setup as a a TwinRx) with a BasicRx I get a
"uhd::assertion_error". If it is not currently supported could it b
Hi,
I am capturing 75 MHz using 100 MSps sample rate as well as using 200 MSps
sample rate but I am not getting the near-end bands with 100 MSps while I am
getting those with 200 MSps. What I have done is capture the data and then pass
it through a polyphase channelizer to give me 200 K bandwi
Hi Jason/folks,
Do you know how to generate an FPGA image from Vivado GUI that includes an OOT
block created using rfnocmodtool?
I created an OOT block using rfnocmodtool, run a testbench to verify that it
was ok, then generated a bit file with the uhd_image_builder.py script and
programmed it
Peeps,
I have an X310 on windows with 3.10.2 and a single UBX daughtercard.
get_rx_num_channels always returns 2 even though there is only a single
daughtercard installed.
I am guessing this is really returning the number of DDCs present?
Is there a simple way to get the number of actual c
You could run uhd_usrp_probe and parse the output.

I'd actually recommend doing `uhd_usrp_probe --tree` and figure out
which value you need from that. We don't actually guarantee the
stability of the output of the plain-text uhd_usrp_probe.

Hello list.
I am working on a customization of the fpga code for the USRP B200.
My intention is to put an encoder/modulator inside the fpga (i dont care
for rx for now). I want to do this before the digital upconverter.
The samples coming from the USB bus will not be I/Q samples, but a type of

OK, I can walk the tree and map channels to populated slots based on the name,
assuming Unknown is an unpopulated slot...
Would be nice to have a better abstraction there...
I have noticed that IQ will stream from unpopulated daughtercard slots... Is
this expected?
In testing my app I have
Hi Robin,
The property tree is the abstraction here; you can query it!
Alos, instead of walking the parsed output of some UHD utility, I'd
recommend you just directly query the USRP in the C++/C/Python...
directly, using UHD.

Hi Snehasish,
knowing the roll-off of the halfband filters in the USRP, this is rather
surprising. So, my best guess is that there's might be a problem with
your software, but I can't really assess that.
Best regards,
Marcus
