Re: [USRP-users] Which bandwidth does uhd::usrp::multi_usrp::set_rx_bandwidth set?

2019-02-22 Thread Martin Braun via USRP-users
Janos, the purpose of the the API call is to configure analog filters, and not the sampling rate. If your analog bandwidth is lower than the sampling rate, there's nothing wrong with that. In fact, for the AD9361-based devices, this is not unusual, since the analog bandwidth is 56 MHz, but the max

Armin, I'd like to learn a little more about this failure. Here's a couple of questions: - How many USRPs are you running at once? Does this also happen with a single USRP? - Does this also happen when using a vanilla UHD example? Since you're running a custom RFNOC block, it would be good to elim

This pokes a register in the STC3. It'll pull the FPGA into reset. You then need to wait a bit before the FPGA is back up. -- M On Fri, Feb 22, 2019 at 10:21 AM Brian Padalino via USRP-users < usrp-users@lists.ettus.com> wrote: > On Wed, Feb 20, 2019 at 7:45 PM Jonathon Pendlum < > jonathon.pend

You can feed the OctoClock from the X310, and then use the OctoClock's output to drive the N210. All devices will be synchronized, in frequency, and the N210s will be synchronized in time, but the X310 and N210s will not be synchronized in time. However, that timing offset you might able to calibra

Rob, yes, you can query UHD_RFNOC_FOUND. Check out this example: https://github.com/EttusResearch/gr-ettus/blob/dcb780b77a114a265bb355fdba4f24033c3412c4/CMakeLists.txt#L138-L141 -- M On Wed, Feb 20, 2019 at 8:52 AM Rob Kossler via USRP-users < usrp-users@lists.ettus.com> wrote: > Hi, > I have a
