Block processing and printing results in python

GNU Radio
1

Hello,

I would like to repeatedly compute signal characteristics for
consecutive
blocks of data from the USRP, while echoing the results to the screen
(e.g.
mean,etc.). I would prefer to do this within python without writing my
own
signal processing block. Is this possible without writing my own block?

Thanks,
Rob

Depending on what you’re trying to measure, this is possible.
See for example

gnuradio-core/src/lib/general/

gr_probe_signal_f.h
gr_probe_signal_c.h
gr_probe_signal_avg_mag_sqrd_f.h
gr_probe_signal_avg_mag_sqrd_c.h

    gr_probe_signal_avg_mag_sqrd_c.h

I was looking for something like this too, but from what I can see,
gr_probe_signal_c.* is not available in trunk (rev. 4796). Am I
missing something?

They’re in 4796. Are you sure you’re looking at the trunk?
