The 450 ms are indeed a generous upper boundary for tune duration –
however, since the B200 can't sample-time analog tunes, you'd do well
not to calculate much less; the B200 is generally much faster at
tuning, but when crossing certain frequency span boundaries, there's a
single tune that might
At my former employer we were using the HackRF in sweep mode to do I think
100 MHz to 6 GHz sweeps at 1 Hz (i.e. almost 6 GHz scanned each second).
For contiguous sweeps I think it used a non-configurable 7.5 MHz (RF tuned)
step or something like that, but gave you much better frequency resolution
Thanks Marcus, indeed I'm using B200's for this project. X300's are
slightly over my budget unfortunately... but I'm also interested in doing
the same with RTL dongles.
You mention 450ms for tuning a B200 - that seems rather longish?

so, 60 steps in 3 Minutes… sounds absolutely doable with the Ettus B200
(you asked about UHD drivers, so I presume you mean USRPs – the RTL
dongle has nothing to do with UHD) and the usrp_spectrum_sense.py
script that comes with GNU Radio. Even if I do not endorse the
architecture of that script,
Yet another probably 80% solution is rtl_power which emits a CSV of power
and rtl_heatmap which generates images.

I know that
At my work we're using R EB500s for continuous spectrum monitoring at our
sites of interest. These machines step through the frequencies 70 - 3000
MHz in about 3 minutes in chunks of 50 MHz (from memory), and then assemble
the fragments into a contiguous waterfall display.
