I'll observe that with a 30dB attenuator in front of your receiver, you
can easily do what you want
  to do.  I suspect that you don't know that much about the RF world,
otherwise the $5.00 attenuator
  solution would immediately occur to you as a more economically-sound
solution than a
  $2800.00 system replacement.

Further, the FPGAs on the USRPs are programmable, and the souce Verilog
is publically available
  for you to modify, etc, etc.

Note that I'm not saying *dont buy* your Altera development board--it's
your $2800.00, do what you
  want with it, but if the reasons are just the attenuator and "I want
to program my own FPGA", then
  you already pretty-much have what you need.
