[USRP-users] Getting sensor data using device3 usrp on E310

Hello, I would like to access sensor data like "gps_time", "ref_locked","gps_locked" using a USRP device defined as "uhd::device3::sptr usrp" on a E310 unit. All the examples are for USRP devices defined as "uhd::usrp::multi_usrp::sptr usrp". I searched the documentation and tried all possible co

[USRP-users] Failed to compile UHD 3.15 on E310 target

Hello, I made a small modification to UHD and would like to compile and use my version. Since I never succeeded to cross-compile I decided to try to compile it on the target itself. I am working with an USRP E310. I cloned the 3.15.LTS repository, modified one of the files and tried to compile. Du

[USRP-users] Can E320 support RFNoC Replay block?

Hello, Looking at the FPGA code on the repository for E320 I see that the replay block was previously supported and reverted to a FIFO a few months ago. Is it not working properly? Can I get a previous version of the FPGA firmware and use the replay block on a E320? Regards, Ofer Saferman -- Th

[USRP-users] Hacking E310 units for synchronization

Hello, I must say that I am a bit frustrated. When I purchased multiple E310 units it was with the hope I will be able to synchronize them mainly based on: https://kb.ettus.com/Synchronization_and_MIMO_Capability_with_USRP_Devices, it shows the E310 as MIMO capable and having a reference clock inp

[USRP-users] Synchronization of E310 units

Hello, I asked a few weeks ago about the possibility to use the internal GPS receivers of the E310 to synchronize multiple units. Someone explained that the internal GPS receiver and its associated synchronization algorithm are not good enough and I will not get synchronization that is better tha

[USRP-users] Using GPS disciplining on E310

Hello, I would like to synchronize several E310 devices. It is my understanding that the only way to do that is by connecting a GPS antenna and performing disciplining to a derived 1-PPS signal. I have a few questions to help me better understand how to make it work: 1. Does GPS disciplining achiev

Hello, I would like to extend the example called "rfnoc_replay_sample_from_file" to play 2 files, one for Tx1 and one for Tx2. I would also like both playbacks to start simultaneously (be synchronized). Is the synchronization possible? What would be the methodology? Creating 2 instances of the re
