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? Cheers - Balt On 29 March 2018 at 06:04, Müller, Marcus (CEL)

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. On Tue, Mar 27, 2018 at 8:10 PM, Kevin Reid wrote: > On Tue, Mar 27, 2018 at 6:19 PM, Balthasar Indermuehle > wrote: >> >> Is anyone aware of a

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. Is anyone aware of a
