Affordable, high-performing RF spectrum analyzers and signal generators.

Signal Hound spectrum analyzers were created for a very specific purpose: to provide high-quality RF spectrum analysis tools at a price that won’t break the bank. We have a few different models, but they all carry similar core features:

Powered over your PC’s USB connection (except the SM200B/C, which uses a power supply);

Signal Hound USB

Managed via Signal Hound’s robust (free!) spectrum analysis software;

Signal Hound Spike

Small enough to easily hold in one hand (okay, so the SM200B/C is a little bigger, but not much);

Signal Hound Small

Extremely powerful & capable, right out of the box!

Signal Hound Powerful

Signal Hound delivers unrivaled value in RF test and measurement equipment

Signal Hound products are designed to deliver accurate and thorough RF analysis measurements at a fraction of the cost of typical high-end test equipment. With today’s test equipment ranging from a few hundred dollars for low-end devices to over six figures for high-end products, Signal Hound aims to deliver quality and performance near the high-end, with a price trending down toward the low-end.

You don’t always need expensive or overly complex test equipment to get the job done. We build our devices to include the important features and functionality you’d find in higher-end tools, but keep things lean by leaving out the non-essential. We work hard to deliver accurate and powerful RF analysis capabilities for smaller budgets and to give larger budgets the opportunity to put more devices in the field without increasing spend.

Whether you’re needing EMC precompliance capabilities in a small two-person shop, or spectrum monitoring on a national scale, this test equipment is designed with you in mind. Accurate and powerful enough for mission-critical RF analysis, priced at a point accessible to most, and supported by a talented group of engineers committed to what they do – we truly believe that Signal Hound devices offer unrivaled value in the test equipment industry.
