Try setting num_recv_frames=128 In the device arguments, and see if this helps. Also, the B210 has a flexible master clock--the UHD drivers will pick a master clock rate that provides good filtering performance for your chosen sample rate, at 10Msps, a 40MHz master clock is an appropriate choice made by the driver. Also, keep in mind that even when you aren't "doing anything" with the samples (as in your Gnu Radio example), a *tremendous* amount of "stuff" has to happen to those samples on the way up from the hardware in to your application. |
