R5750 Real-Time Spectrum Analyzer
with GPS/GNSS
Built for drive testing and coverage mapping teams, geolocation and direction-finding operators, and mobile signals intelligence (SIGINT) teams, the thinkRF R5750 is a compact, real-time spectrum analyzer with integrated GNSS that scans RF spectrum from 9 kHz to 27 GHz continuously, capturing signals with up to 100 MHz of instantaneous bandwidth alongside precise location and time data for every measurement. Fanless and network-connected, it operates in the lab, field, or vehicle with remote control over 1G Ethernet, and integrates with custom applications via SCPI, VITA-49 VRT, and LibTRF APIs. Paired with thinkRF’s Spectraware software, it combines real-time signal analysis with situational awareness for mobile and distributed monitoring.

MOBILE RF APPLICATIONS FOR WIRELESS SITUATIONAL AWARENESS WITH thinkRF R5750
The thinkRF R5750 Real-Time Spectrum Analyzer with GPS/GNSS is built on innovative software-defined radio (SDR) technology, designed specifically for mobile wireless situational awareness applications. Its highly optimizable architecture allows capabilities to be extended through software without replacing hardware.
Built for RF drive testing, coverage mapping, propagation analysis, direction finding, transmitter localization, and vehicle-based spectrum monitoring, the thinkRF R5750 embeds GPS/GNSS position and time data directly into every measurement – so engineers in the field always know the location and time of each capture.
Compact, lightweight, and fanless, the thinkRF R5750 offers low power consumption and increased portability for outdoor and mobile deployments. A weather-resistant option provides additional durability in challenging environments.
When paired with Spectraware spectrum analysis software and our application ecosystem, the thinkRF R5750 delivers a complete mobile spectrum analysis solution – from real-time signal capture and geolocation to post-processing and reporting.
Deploy a wireless sensor network of thinkRF R5750 units across a wide geographic area – in the field or on vehicles – for distributed, continuous coverage monitoring.
Geolocate and find direction of a signal of interest using Time Difference of Arrival (TDOA), Power Difference of Arrival (PDOA), Frequency Difference of Arrival (FDOA) or Angle of Arrival (AOA) techniques.
Up to 100 MHz real-time instantaneous bandwidth and greater than 100 dB dynamic range deliver improved spectral performance for deeper analysis of complex waveforms.
Reduced size, weight, and power (SWaP) requirements make the thinkRF R5750 ideal for deployment in trucks, cars, military vehicles, UAVs, and boats – maximum portability without sacrificing performance.
Increased functionality and greater frequency coverage than traditional handheld spectrum analyzers – covering 9 kHz to 27 GHz with up to 100 MHz real-time instantaneous bandwidth.
Built-in GNSS/GPS
The thinkRF R5750 synchronizes positional and temporal information with signal data, giving users a complete map of the signal environment with every measurement. Knowing the location and time of each capture is the foundation of all mobile wireless situational awareness applications.
GPS and GNSS data is embedded directly into VITA-49 VRT data packets, enabling seamless correlation between RF measurements and geographic coordinates in downstream analysis tools.
Networked & Remote Deployable
The thinkRF R5750 is designed for networked deployment, supporting time-synchronous spectral measurements across distributed sensor arrays. This enables emitter location, direction finding (DF), and propagation study applications across wide geographic areas.
Geolocation measurements can be performed using time-based techniques (Time Difference of Arrival – TDOA) or power-based techniques (Received Signal Strength – RSS), depending on deployment requirements.
Multi-unit synchronization is supported via two methods: GPS for outdoor deployments, and a 10 MHz reference in a master-slave configuration for indoor deployments or environments where GPS is unavailable.
Wide Frequency Range
The thinkRF R5750 covers a frequency range from 9 kHz to 27 GHz with up to 100 MHz instantaneous bandwidth and a sweep rate of 28 GHz/s. This performance envelope provides the coverage required to analyze today’s complex, dense, and dispersed wireless signal environments including 4G LTE, 5G NR, and legacy bands.
SWaP Compact & PC-Driven
The thinkRF R5750 connects to any standard PC via Ethernet, leveraging modern computing and networking advances without requiring proprietary controllers or dedicated hardware. Its compact, lightweight, and low-power design makes it well-suited for deployment in vehicles including trucks, cars, military vehicles, UAVs, and boats.
Unlike traditional bulky spectrum analyzers, the thinkRF R5750 is easily upgradable through software, extending its capabilities without requiring hardware replacement.
APIs & Protocols Proven Integrations
The thinkRF R5750 supports integration with custom applications and third-party software through three open APIs:
● SCPI – instrument control compatibility with standard test automation frameworks
● VITA-49 VRT – standardized data streaming with embedded GNSS metadata
● LibTRF – C/C++ library for direct hardware access and custom application development
