[Discuss-gnuradio] New digitizer hardware

[Theo Verelst]

Hi all,

I saw there was talk of usrp2, is that new digitizer hardware, or new
software for the existing USRP ?

In case it is new, maybe it is a good idea to take two FPGA's aboard 
the machine, such as to be able to do signal processing on one, and 
leave the other preprogrammed when no need to adapt the standard signal 
processing and interfaces.

In fact there are even development boards with built in FPGA with
significant capacity which could be interesting like this TI one:

Is it hard to make a generally usable ethernet or Usb connection to 
yield the high bandwidths needed for signal input, or is it a matter 
of industrial interest that such units (as exist for disk drives 
and such) are hard to get, and also not easily makeble from the sr
sources?

The  same for the receiver design: am I istaking or are even the open 
diagrams deliberately hard to read in aspects and containing less 
regular parts? In the HAM world it isn't considered a crime to make 
ones own hardware and usually seems not to interfere with business 
interests too much, or is the IT world in the way?

Kind Regards,
