That should be the right answer, but is not completely reliable. Try running test_usrp_standard_rx with different values of the -D <decim> option. Start with -D 128, then try -D 64, -D 32, -D 16, -D 8. -D 128 500kS/sec 2MB/sec -D 64 1MS/sec 4MB/sec -D 32 2MS/sec 8MB/sec -D 16 4MS/sec 16MB/sec -D 8 8MS/sec 32MB/sec Likewise, try test_usrp_standard_tx with different values of the -I <interp> option. Start with -I 256, then try -I 128, 64, 32, 16. -I 256 500kS/sec 2MB/sec -I 128 1MS/sec 4MB/sec -I 64 2MS/sec 8MB/sec -I 32 4MS/sec 16MB/sec -I 16 8MS/sec 32MB/sec A couple of over/run-runs at the beginning is OK for any given attempt. (Note, I just fixed a minor problem that would show 5 or more tx_underruns at the beginning. Update usrp from CVS if you want the fix.)
