Hi,
Can someone tell me how to use usrp_oscope.py and usrp_fft.py? I tried
looking for answers on the archive but couldn’t find any.

Thanks,
Ali

Mir A.:

Launch the apps just like you would any other program. Just type
“usrp_fft.py” then press enter. Select the frequency you want to look
at using the text box in the corner. You can use abbreviations such as
“4M” instead of typing out “4000000”. The blue squiggle line is a plot
of power vs frequency.

Thanks for all your help. I have one more question. At which point in
the
flowgraph does usrp_oscope capture and display the data.

Thanks,
Ali
