Hi Padorin, Yes the B210 supports 2x2 @ 30.72e6, but is dependent upon your host system and USB controllers.
You can try using sc12 OTW format which may help: ./benchmark_rate --rx_otw sc12 --tx_otw sc12 ...... Also ensure you've set your CPU governor to performance, and enabled thread prioirty scheduling as detailed here https://kb.ettus.com/USRP_Host_Performance_Tuning_Tips_and_Tricks Regards, Nate Temple On Thu, Dec 12, 2019 at 7:45 PM Padorin Kurpinsky via USRP-users < usrp-users@lists.ettus.com> wrote: > Hi all, > > The USRP B210 spec [1] says it supports 30.72 MHz of instantaneous > bandwidth.
