Thank you Thomas (and Marcus)

for the replies. I've been using the 8 bit mode un the USRP1 a while ago for a different application. I was looking for a slightly higher precision.

I did not know that the usrp2 could not do the 8bit sampling. Thanks for the info.

Regards

Vince

At one time, there were plans to implement a user-configurable "shift and mask" approach to bit precision on the USRP1 end, along with appropriate packing routines, etc. But this never
  happened, so there's 16-bit and 8-bit, and nothing in between.

The changes require support in the USRP1 uController code, and the support code on the Gnu Radio
  end.  While not that difficult, they're not that trivial, either.
