dear all,

i am suffering an under run error when running the tx_waveforms.cpp example i tried it on the BASIC and WBX daughter boards and i tried several combinations (i.e. amplitude ,frequency ,SPB ,wave frequency , wave form) but nothing works i am using USRP1 if any body has a certain combination that worked with a certain daughter board i would appreciate his help


Underruns are entirely independent of which daughterboard you're using.  it means that your
  computer can't keep up with the requested sample rate, and can't provide samples to the
  hardware fast enough.  Try a lower sample rate.
