Hello,
I am trying to get samples from a B200 at 50 Msps into GNU Radio. The
UHD benchmark_rate tool receives at 50 Msps without any overflows
detected. My GNU Radio flowgraph is simply a USRP source connected to
a null sink, and I'm still getting overflows. I've tried expanding the
min_output_buffer for the USRP source, but that doesn't seem to help.
I really don't know what is causing the problem. Any suggestions about
what I should try?
Thank you,
Orin Lincoln
On bladeRF, the number of USB3.0 buffers makes a big difference
in the maximum sample rate without overruns. On the B200, you
can try the same thing by increasing the number of buffers
in the device_addr arguments.
device_addr="recv_frame_size=65536,num_recv_frames=128,...."
