Re: [USRP-users] Time synchronization of multiple B210s not working with multiple channels

2020-02-27 Thread Michael Wentz via USRP-users
Hi Ian, To answer your questions: - The absolute times after run are around the 6 second mark as expected, just with some additional 10s to 100s of microseconds that appears random on each B210. - All of the B210s are powered by the 5.9V 4.0A adapter they came with. Now some good news: I think I'

[USRP-users] Building and Installing UHD with RFNoC and GNURadio 3.8 from source with Tensorflow 2.0 integration

Hey all, So I need some direction for what I am trying to do as I am not sure that it is even possible. We are using machine learning in the project I am working on, and would like to incorporate that into GNURadio if possible. So I am currently using an anaconda environment set up with python3

Hi Jerrid, I made some conda packages for UHD and GNU Radio 3.8 that are available on conda-forge: https://conda-forge.org/. That might be a good way for you to get things running in the same python environment. The UHD package does include the Python API. The only caveat is that the GNU Radio

[USRP-users] How do timed commands work for two blocks (USRP Sink+USRP Source)?

2020-02-27 Thread Lukas Haase via USRP-users
How do these timed commands work exactly when using USRP Source together with USRP Sink? (I need to phase-align RX and TX hence use timed commands at the same time). Since they are both internally use the same hardware device (and board) I feel timed commands sent to both blocks result in some u

A quick update which may make things easier to debug: I am observing TX/RX on a spectrum analyzer and see if the frequency changes. As soon as I enable timed command, the tune command is ignored! For simplicity, I am completely removing the RX parts (uhd_usrp_source_0). Now this works: tune_req
