Hello,
We are using an NI Ettus USRP X410 SDR. We have been successful in programming the FPGA images that are default UHD designs as well as our own custom FPGA design utilizing a singular RFNoC block.
Once we integrated our FPGA Design which includes an ILA to view what the signal looks like at the input/output of our block we observed a tone that would be generated any time the stream command would be set, regardless if a tone was present or not.
[cid:image001.png@01DAD794.0F1FE0D0]
The SW used was based of the rfnoc_rx_to_file script, with the addition solely being specifying the RFNoC block added. Other than that the script was not changed. It was observed that the frequency of the unknown tone would change as the LO was tuned via the "freq" flag.
We then reverted to the default FPGA design usrp_x410_fpga_CG_400.bit and ran some of the benchmark tests provided (https://kb.ettus.com/Verifying_the_Operation_of_the_USRP_Using_UHD_and_GNU_Radio#Benchmarking_your_system).
Below are the commands and results:

The main question is where is the tone originating from when streaming if not through the signal generator, is there some internal DDS being configured upon tuning? Or what other scripts can be used to verify using the RFNoC SW API. Thanks!
Hi,
some pointers:
- It would probably help figuring out stable streaming before moving on.
You can start with a 200 MHz image and drop the sampling rate. The
192.168.1.123 interface, is that a 100 GbE interface? Because the RX
streaming rate info at the end almost seems like you're using the RJ45 1GbE
interface (which is fine -- but you can't stream to/from a radio on a 400
MHz image that way) - I'm not sure about the tone, but when you RX without your block into a
GUI application (like uhd_fft, gqrx, or, if you're being super
minimalistic, rx_ascii_art_dft), do you see a tone in the spectrum? Maybe
it's some naturally occurring leakage. ILAs are great tools, but not always
ideal for detailed analysis of signals. There are a bunch of LOs and
there's a DDS in the RFSoC, but the DDS shouldn't be present here. - If your FPGA isn't too full, put your custom block on its own stream
endpoints. Then you can stream data directly to the block and back for
testing with better control over your input vectors.
