USRP source + UHD driver and data formatting

Did the USRP IQ data format change in the UHD driver? The data from the
USRP1 used to be 15-bit fixed point, or something like that, is it now
normalized floating point data? I’m asking because I have code that
moves data from the USRP to a Fixed-point DSP and it seems I have to
redo the data conversion part so can someone explain to me the new IQ
data format?

Also is this the same data format expected for the USRP sink?

thanks

Yes, all floating points are normalized to 1.0. Integers are not. See:
