Your intuition is correct. The Basic TX and RX boards allow this -- they don't do any RF front-end processing.
The Basic boards let you make the USRP into a poor man's oscope, with very limited voltage ranges on the input. -Ian On 9/7/07, Rohit Garg <[EMAIL PROTECTED]> wrote: > Hi, > > I am curious about what you have created.
