Re: 2 SDRs – Parallel Programming

Hi, I explicitly mentioned the time stamps you need to set. You're not setting these, so it doesn't use timed commands. Best, Marcus On 05.01.24 13:38, Oğuzhan Gedikli wrote: Hello Marcus, The boards  I have are b200 and b210. I want to change the frequency of 2 SDRs at the same time. Eve

Maybe my brain is frozen in the past and it is very doable now, but that hasn’t been my experience. --- Jim Melton Sent: Friday, January 5, 2024 05:39 To: marcus.muel...@ettus.com; discuss-gnuradio@gnu.org Subject: [EXTERNAL] Re: 2 SDRs – Parallel Program

Re: 2 SDRs – Parallel Programming

Hello Marcus, The boards I have are b200 and b210. I want to change the frequency of 2 SDRs at the same time. Even if I write the codes in parallel, the frequency of one of the SDRs changes first, and then the frequency of the other one changes. I want 2 of them to run in parallel. I looked a

Re: 2 SDRs – Parallel Programming

Hello Oğuzhan, so, what radios are these? Generally, this *very* much sounds like you need to use timed commands, which trigger the tuning at a specific sample time, instead of "yeah, whenever the connection between PC and the USRP has delivered the command". You can send these commands to t
