Hi Olivia, I was able to make your flow graph build just beautifully, simply by adding a "new" UHD USRP Sink and UHD USRP Source block, and manually copying the settings over from the original blocks, then removing them. I'll guess it's a problem caused by changes to the USRP Blocks between w

Hi Dario, you're right, that currently doesn't exist. R&D is aware of that, and from what I hear through the grapevine, it's something that they want to re-establish functionally (don't know whether that means "forward-porting" the old tool or writing a new one). Alas, there's nothing that we

Hello Mark, I'm afraid there isn't a straightforward way of doing that; can't really think of a way that would enable that short of inventing another "radio block"-style RFNoC core that handles these GPIOs as separate channels; and that would be a pretty big endeavour. Best, Marcus On 17.01.

Hi, I am working with an x310 + the UBX-160 daughter card. Ettus has a couple of URLs with various block diagrams and plots:  BLOCK DIAGRAM: https://files.ettus.com/schematics/ubx/UBX-160_revE.pdf and performance measurements (plots: Pwr, OIP2, OIP3 etc.)  PLOTS:  https://files.ettus.c
