TinySA Ultra Spectrum Analyzer

The TinySA is an incredibly powerful Signals Intelligence (SIGINT) collection tool which displays a broad spectrum of received signals in real time. Much of the appeal of using software defined radio (SDR) in the SIGINT role is for its visual capabilities. This eliminates the need for requiring a laptop or tablet and puts that capability in a field portable kit.

The TinSA Ultra is the best of the small spectrum analyzers currently offered on the market. With a 4in color touch screen, it displays both the spikes as well as a waterfall for signal analysis. In the SIGINT course we attach these to improvised Yagis and Jungle Antennas for broadband signals collection and radio direction finding (RDF). Its wideband reception capability (100 khz - 5.3Ghz) receives not only radio traffic but anything else in the upper ends of the RF spectrum, providing early warning against cell phones, advanced 4G/5G based ground communications, and drones.

I consider this the critical tool for tactical signals exploitation (TSE), followed by a communications receiver.
