[USRP-users] Re: Error in building USRP FPGA bitstream module 'rfnoc_block_fft' not found

I reformed my previous post, I used this command, so when I want to build with GUI=1 option I was faced with some errors make X300_HG GUI=1 but when I want to make without GUI=1 option I have not any eros... how can solve this problem? On Mon, Jan 31, 2022 at 2:40 PM sp h wrote: > when I want to

[USRP-users] Transmit 2 tx channels with USRP E320

Hi all, I try to transmit a signal through an RFNoC Radio TX block in a USRP E320. I am using UHD 4.0 and GNURadio 3.8. My flowgraph in Gnuradio is something like this: Host block => RFNoC tx Streamer => RFNoC custom block => RFNoC DUC => RFNoC tx radio When I test this graph with "number of por

[USRP-users] Re: Transmit 2 tx channels with USRP E320

I forgot to mention that when I set 2 inputs in DUC and RFNOC blocks, in0 takes rfnoc custom block output and in1 takes the following chain: host block => rfnoc tx streamer => DUC => radio ___ USRP-users mailing list -- usrp-users@lists.ettus.com To un

[USRP-users] Re: Timed Commands Not Working

Thanks, Rob. I always appreciate when you "chime in". Hopefully, someone can try the uhd "test_timed_commands" example in 4.1 to help confirm whether or not it's a problem with something on my end or with UHD. Marcus already confirmed its working for him with an N310 and UHD 3.15. Thanks, Jim

[USRP-users] Re: Here's how to get the N321's LO sharing to work in GNURadio 3.9 with UHD4.1.0.5

Hey Daniel. Glad you like it. The functionality is there for now, but I have some reservations about recommending this for upstream. TLDR: more work probly needs to be done for the changes to be stable. My suggestions/concerns on upstream changes are as follows: 1) If the file system naming c

[USRP-users] Timed Commands compatibility between different USRP series

Hi there, We have a simple set up where we collect iq snippets from 3 usrp's at the same rx-times via timed commands. We introduce delays between the usrp's via a reference delay box and try to recover the introduced delays via cross-correlation. Things work great when all the rx's belong to the

[USRP-users] Re: Timed Commands compatibility between different USRP series

Thanks for the prompt response Marcus. Should the discrepancies express themselves as a constant offset in cross-correlation or can the delay measurements also oscillate in a volatile fashion? For B210-E310 we see a more constant looking offset whereas B210-X310 is just wild. Also I remembered thi

[USRP-users] Re: Timed Commands compatibility between different USRP series

Thanks for the clarification. We are using GPSDO to provide 10 MHz/PPS to the USRPs. Jackson Labs OCXO for the X310 and TCXO for the B210. For E310 we just use the GPS antenna which I guess is connected to a ublox module. Best, John On Thu, Feb 3, 2022 at 11:42 PM Marcus D. Leech wrote: > On 20

[USRP-users] N320: external ref clock with internal gpsdo timing source

Hi all, I'm working with an N320 and UHD 4.1, and I plan to use an external reference clock (a 10MHz OCXO for reasons of RF phase stability) and the radio's internal GPSDO for timing (to synchronize capture start times across radios). I found that "clock_source=external,time_source=gpsdo" is no
