Issue Details

Is it posible to use USRP RIO onboard FPGA to calculate FFT of received signal? 

Solution

Yes, it is posible. 
USRP RIO FPGA programming have lots in common with FlexRIO. So you can use examples shipped with FlexRIO driver as algorithms implementation examples for USRP RIO devises.

There are bunch of FFT computing examples shipped with FlexRIO Driver. To find it in LabView select Help-> Find Examples... it'll show NI Example Finder. On the Search tab type FFT.
