>The OSCOR Green Spectrum Analyzer is designed to detect illicit eavesdropping signals, perform site surveys for communication systems, conduct radio frequency (RF) emissions analysis, and investigate misuse of the RF spectrum. The OSCOR Green is a portable spectrum analyzer that sweeps 24 GHz in one second to quickly detect transmitting electronic surveillance devices and ensure that spectrum activity is captured.>detect illicit eavesdropping
Wtf is this magic? >signals
OK. Deceptive description. >it's a portable spectrum analyzer >sweeps 24ghz/seconds
A cheap alternative would be the hackrf.
I remember this talk where they made it really fast i believe:https://youtu.be/XNcGhnY_0oIhttps://github.com/xmikos/qspectrumanalyzer/blob/master/README.rst
But I don't think thats quite the 24ghz/second speed.
