Re: [USRP-users] UHD make stopped on 100% with error 1

That being said, I don't think UHD acutely requires anything not in Ubuntu16.04 (though I agree, that feels ancient). I'm running a test build, i.e. docker run -it ubuntu:16.04 $ apt-get update $ # and of course, Canonical couldn't get their mess together, so they $ # forgot to supply proper verf

Hello, Thanks for your quick response! Actually, I have GNU radio flow graph as per my application which runs through UHD USRP sink and UHD USRP source to USRP B200 mini hardware, right. But now as you said we can use USB to serial converter for transmitting data from outside source. but for th

Hi all, Great thanks for support! I re-installed my OS, it was definitely screwed up after two years of experiments. UHD installed with no issues at all at new shiny installation of old known Ubuntu 16.04.5. Thanks again! On Wednesday, January 9, 2019, Marcus Müller wrote: > That being said,

[USRP-users] use a usrp x310 as MIMO transmitter, daughterboard synchronization?

2019-01-09 Thread Yang Liu via USRP-users
Dear all, I have a usrp x310 with two UBXs installed. And I want to use it as a MIMO transmitter (two outgoing channels streaming at the same frequency). When we need to build a MIMO system by connecting different usrps, I know that we need to have either MIMO cable or external time and frequency

Yes they’ll use the same reference clock provided by the motherboard. There’ll be a residual phase offset which can be mitigated using timed tuning. Sent from my iPhone > On Jan 9, 2019, at 3:01 PM, Yang Liu via USRP-users > wrote: > > Dear all, > > I have a usrp x310 with two UBXs instal

Hello, i tried to get the N210 working with external clock source on GQRX by adding the following to the device string: *clock_source*=*external* *But it is not working.* *With gnuradio the external clock source is working fine.* *Please, anyone can help me?* _

Hi Andre, GQRX uses gr-osmosdr under the hood to interface to the USRP, the setters and getters are there [0] to set the sources for an external ref/timing source, but it does not parse the device arg to set them [1]. If you add the parsing and rebuild gr-osmosdr and then GQRX, it will work. htt

Hi Marcus, Thanks! I feel a little confused about the term 'frequency synchronization'. if the two LOs on the two daughterboads are using the same frequency reference, does it mean that after tuning, they will produce identical CFOs to the same receiver (one receiving channel) or we can say that

Hello, Thanks for your quick response! so, with B200 mini, it is not possible to use GNU radio to work on board itself, Can you please suggest me the software such as labview can be used on it(USRP-B200 mini) without the host computer or only VHDL-verilog is supported on this particular SDR.
