Big Performance Has Never Been So Small.

Traditional Spectrum analyzers try to fit the signal acquisition, processing, analytics and storage into one expensive and unwieldy box. But what if you could still perform great RF spectrum analysis easily at a lower cost? And what if you could get that analysis and support anywhere at any time? Tektronix USB spectrum analyzers deliver full-featured real-time analysis solutions at a fraction of the cost in highly portability form factors by disaggregating the functions of traditional spectrum analyzers. By moving the data analysis, storage and replay capabilities of a traditional spectrum analyzer to PCs and tablets via a powerful software platform, Tektronix USB real time spectrum analyzers have be sized down and optimized to perform fast and robust signal acquisition in real-time with a smaller, less expensive instrument.

All Tektronix RSAs use our 6th Generation DPX® Technology and real-time architecture so you can see signals never seen before on a swept instrument. SignalVu-PC® software offers 17 free measurements and 15 application-specific packages, enabling you to build an analysis solution that makes your work easier, faster, and more productive.

RSA Features

Performance with No Compromises.
The RSA Series provides performance to match conventional mid-range spectrum analyzers on the market. No compromises are required for even your toughest challenges.

Unequaled Size. Unlimited Flexibility.
Conveniently sized for easy portability from your bench, the lab or even the field. It’s powered by your laptop or tablet giving you the ultimate flexibility and convenience. You choose the display and connectivity that you prefer.

See More with Proprietary DPX® Technology
Discover the most difficult, hard-to-find problems with the powerful real-time architecture of the RSA Series. With the advanced DPX® technology, you can see RF characteristics that are practically invisible to a conventional spectrum analyzer.

Powerful and Intuitive. Measurement Insight at your Fingertips.
The RSA Series is powered by SignalVu® Essentials software – the same software used on the full-line of Tektronix Real-time Spectrum Analyzers. Delivering unlimited access to advanced measurement and analysis capabilities that you can save, customize or share with peers. Over 15 packages cover common wireless standards, spectrum management, pulse measurements and more.

RSA Featured Applications

Field Test Made Simple.
The RSA Series provides a full toolbox of features for common field test tasks. Scan the spectrum to find interfering signals, and be confident you’ll capture any signal lasting at least 100 µsec - 100% of the time. Measure cables, antennas, and other RF components like filters and amplifiers with the built-in tracking generator. Built-in GPS provides geo-location details to enable mapping of 6 different types of information.

Complete Wireless Standards Testing at an Impressive Price – Bluetooth, WLAN, Zigbee and More
With 40 MHz of real-time bandwidth standard, the RSA Series can demodulate and measure modulation quality on even wideband signals like 802.11n or capture multiple Bluetooth signal hops in one snapshot.

Don’t Fail Your EMI Compliance Test.
Ensure that you don't overspend time or money on multiple tests at EMI Compliance houses by running pre-compliance tests in your lab, as early and often as you can. The RSA Series offers a range of tools to help you do this simply and easily.
