I am trying to modify usrp_fft.py(oscilloscope mode) to display a longer
duration of decimated data in real time. I think in the default
oscilloscope 5msec of data is displayed(whatever the decimation rate and
time/div is) and these length of data is updated in real time.
What I want is to decrease the decimation rate to 1KS/sec(64MS/sec
decimated by 128 in FPGA and then by 500 using decimating lowpass
filter) and display 5sec of data and to update this 5sec of data slowly
in real time.
How can I modify the 5msec default length to 5sec?
