Signal Hound created its first USB-powered spectrum analyzer in 2010 with the goal of packing significant RF analysis capabilities into a compact and affordable device. Since then, Signal Hound has regularly added innovative new models and no-cost upgrades to their Spike spectrum analyzer software. Their latest product, the SM200A, is a broadband, real-time spectrum analyzer and monitoring receiver well-suited for applications in cellular, military, aerospace, TSCM, automotive and radar. Competing with RF analyzers up to 7x their cost, Signal Hound devices offer reliable performance and unparalleled value. All Signal Hound products are proudly designed and built in the USA.
