SDR Hardware Functions

GNU Radio
1

All,

In using usrp_rx_cfile.py, I pull complex I and Q data off of the USRP.
I
was wondering if this data is handled in any analog fashion in the mixed
signal processor, or if the data is only handled in the FPGA.

To be specific, I want to know if, when using the GNU Radio USRP
functions
(like those called by usrp_rx_cfile.py), if the USRP is behaving as a
TRUE
software-defined radio, or if any filtering or other such
software-implementable functions are instead being handled by the
hardware
on the USRP itself

I may not have my understanding of the way the hardware handles signals
quite correct, but hopefully it’s coherent :slight_smile:

Thanks,

Written
