USB-SA124B: Frequency Sweeps up to 140 MHz per second . So it can cover 6 GHz in 43 seconds, 12.4 GHz in 89 seconds. BW 240 KHz. The BB60C sold by the same company for $2995 has a 24 GHZ/sec sweep speed, goes to 6 GHz instead of 12.4, and has a data bandwidth of 27 MHz. https://signalhound.com/products/bb60c/ This paper, a first google result, appears to describe hacking an Ettus USRP to sweep 5 GHz in 5ms. They describe picking up cell towers at the same time as wifi with one radio. Samples get lost and corrupt; they use calibration to compensate some: https://cseweb.ucsd.edu/~schulman/docs/nsdi19-sweepsense.pdf It's a lot harder to make new things, especially big new things. The USRP can probably already sweep at a reasonable speed. There's probably software to do that. On Sun, Dec 6, 2020 at 8:51 PM Karl <gmkarl@gmail.com> wrote:

I see a 12.4 GHz spectrum analyzer here for $2175. USB-SA124B • 12.4 GHz Spectrum Analyzer | Signal Hound What freq/price-point is Ettus up to these days?
An Ettus USRP is apparently 6 GHz with 50 MS/s bandwidth, and go down to $773: https://www.ettus.com/all-products/usrp-b200mini-board/ . These devices are known for having a gnuradio driver for them.
