[Discuss-gnuradio] Usrp1 wideband fft scope implemented yet?

[Dave]

Does anyone have the spectrum-sense implemeted into a wide band fft GUI display 
yet? Perhaps a private project they might be willing to share ? If anyone is 
working on it let me know if u need any help...

Thank you so much Eric. I've another questions can the DAC data
input frequency be slow down to 25kHz? or make the frequency of data
transmitted from FPGA be slow down to 25kHz? How can I make it?


No.

You can however use the interpolator inside the FPGA
(Digital-Up-Converter, DUC) to do part of the work, then interpolate
in software for the remainder.

Please read the USRP FAQ:
