[USRP-users] uhd rfnoc-devel branch

Hi, could anybody advise if rfnoc-devel branch is regularly synchronized to maint branch? In my case I use rfnoc-devel branch because I want to develop custom RFNoC blocks. From the other hand I need fixes for X310 device I use which are published in maint branch. Should I continue to use rfnoc-d

Re: [USRP-users] uhd rfnoc-devel branch

Hi Dmitry, RFNoC is supported fully only on top of the rfnoc-devel branch, so that is the branch you'd want to use for any custom development. We will merge fixes from master into rfnoc-devel really soon, but if you are having issues that are already solved in maint of master, I believe cherry-pic

Hello Im using X300+TwinRX in Windows.In source UHD 3.10.3 for linux I found example twinrx_freq_hopping.How much I understand in this example the receiver is tuned with the period 5ms.As written in the title of the example, I need to use set_rx_lo_freq.But it is not in the source code of the exam

Re: [USRP-users] twinrx_freq_hopping example

Hello, The tuning time is approximately 5 ms, which is why the example uses that number. The example should work the same on either Windows or Linux. What version of UHD are you using on Windows which does not include it? Are you seeing any streaming errors on Windows? Regards, Derek On Mon, Fe

Hello, Please can you keep your emails in a single thread so it is easier to read. The goal with the frequency hopping example is to instantly jump between frequencies. Normally those 3-5 ms of tuning would be dead time, no meaningful signal could be received. By using the RF synthesizers of both
