ThinkRF delivers a new category of Software-Defined Spectrum Analysis solutions that monitor and analyze complex RF waveforms in today’s rapidly evolving wireless landscape. Remotely deployable, PC-driven and easily-upgraded, the ThinkRF platforms offer greater versatility, better performance and additional capabilities for Research and Development Applications.
The ThinkRF R5500 Real-Time Spectrum Analyzer is built on innovative and highly optimizable software-defined radio (SDR) technologies. This gives users greater versatility, better performance, and additional capabilities to see the full picture in applications such as signals intelligence/electronic intelligence (SIGINT/ELINT), technical surveillance countermeasures (TSCM), and regulatory monitoring. Coupled with real-time digitization and digital signal processing, the R5500 analyzer enables in-depth analysis of complex and wideband waveforms in challenging monitoring environments.

Patented Software-Defined Spectrum Analysis Solution
Networked and Remote Deployable
PC-Driven for Reduced Size, Weight and Power
The ThinkRF S240 Real-Time Spectrum Analysis Software features a completely redesigned graphical user interface (GUI) from previous versions. Designed with the end-user in mind, the S240 keeps common setting such as Frequency, Bandwidth and Amplitude visible at all times, making it easy for the user to get the right view. All other settings and functions are available through an intuitive menu system that minimizes the number of clicks and the time it takes to find the right functions, while still keeping the view of the spectrum front and center. Customized settings can be saved and reloaded to simplify the setup of common applications and uses.


The ThinkRF E300 Enabler allows the ThinkRF R5500 Real-Time Spectrum Analyzer to fully connect with leading Keysight 89600 VSA software. The combined solution provides an integrated and easy-to-use platform that supports over 75 modulation types, enables greater insight into captured signals, and allows for complete vector signal analysis for various research, deployment, and monitoring applications.
Low-cost, flexible, and remotely deployable, the R5500 analyzer with Keysight VSA allows users to reach deeper into signals in time, frequency, and modulation domains, and isolate unexpected interactions with unlimited markers and trace-to-trace marker coupling.
