Learn about Signal Hound spectrum analyzers

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 SM200A, which uses a power supply)

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

Small enough to easily hold in one hand (okay, so the SM200A is a little bigger, but not much)

Extremely powerful & capable, right out of the box

Our mission—to deliver 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, Signal Hound 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.

Reviews from our customers

USB-SA44B — 4.4 GHz Spectrum Analyzer

I bought a USB-SA44B for its small size so I could carry my own analyzer during the installation of satellite downlink equipment. I was particularly pleased with the ease of use of the Spike software. The only thing I would like to see with the ability to start Spike with one of the presets. A great product indeed!

BB60C — 6 GHz Real-time Spectrum Analyzer

This unit is perfect for my lab needs and this is my initial review. I aim to follow up once I have had enough time on it. The Pros ————- Value for money 5 stars Support is excellent from AJ and team Spectrum Analysis, accurate and quick but needs to have a low span as expected for the most accurate frequency match. Marker function is easy to use and deltas are quick to do Digital Demodulation works fine for my needs, lots of options that can be confusing so take your time setting it up EVM measurement is fairly accurate, still getting used to it though The real-time option is very useful but I am still getting used to it as have always in the past used non-real-time analysers This unit replaced an older Agilent I had and I am very happy with it. Cons ——– Getting used to a PC based USB instrument takes time The USB power option unless you have an external compatible hub was problematic for me using a laptop. I had endless disconnection issues until I found a compatible powered hub. I would prefer the unit to come with a separate supply and not take power from USB or a compatibel hub that is powered be supplied with the unit. Thanks for a product that the price is unbeatable. Together with my VSG I can pretty much do everything I need.

USB-SA124B — 12.4 GHz Spectrum Analyzer

We own 4 products from SH: 4 GHz spectrum analyzer in combination with a tracking generator, and the same for the 12 GHz version. We use them extensively for scalar network analysis when building our customized microwave instruments for spectroscopy (in physics). The products have a great price to performance ratio. We had complications when installing the drivers and running the instruments, having a strong hardware was the key. Besides the pros, we encountered a very annoying problem: we often (3-5 times per day) screw-unscrew our units and cables onto the devices. After a few months ,the female SMA connectors broke and started to loose the inner pins. Given that we have other similar devices which have endured the same treatment over several years, we reckon that Signalhound was saving on the quality/cost of the connectors. Given that we were over the guarantee, we attempted to change the connectors ourselves, which has lead to deteriorated performance at 10 GHz. At present, we are using the devices while having a short SMA female-male adapter attached to it permanently, to avoid damage to the connectors on the devices.
