Hi Lucas,
You say you connected TXA to RXA directly via a cox cable? Did you put an
attenuator inline? I am afraid you may have damaged your RX side by
transmitting directly into it without protection. Most USRPs can be
damaged with input power greater than -10 dBm. Disconnect that cable

That's generally good advice, with the single exception of the BASIC/LF
card family--they don't have any gain--they're just ADC/DAC buffers, so
it's generally safe to loop them directly.

hi everyone. i was working with the USRP1. I'm testing a MOD/DEMOD DBPSK. I
have only one USRP, so, i connected TX_A( from daughterboard LFTX-LF) to
RX_A ( from daughterborad LFRX-LF) with a coaxil. All system works well
without URSP but when i taste with the USRP i get so much noise and the SN
