David, Do you know ahead of time what the frequency sweeps are going to be, or do you need to have your RFNoC block creating and scheduling them dynamically?
If you know your frequency sweep list ahead of time, a much easier technique would be for you to send your tune requests from host to radio as timed commands. This way you can queue up hops that will execute at a precise timestamp in your data stream. Depending on the length of your frequency list, you may need to expand the size of the command queue in your FPGA image, but that would be a much more manageable task than creating a block that constructs and issues commands. -Sam On Wed, May 27, 2020 at 7:04 AM Haberleitner David - S1810567006 via USRP-users <[email protected]> wrote: > Hi everyone, > > > for our project we would like to control frontend settings directly from > the hardware to perform fast frequency sweeps. > Is there a way to do that? > > > From out research it seems that the frontend chips (UBX160 in our case) > are controlled via a SPI register in the Radio-NoC block.
