The compact ThinkRF R5x50 Real-Time Spectrum Analyzer series are designed to monitor wireless signals in real-time rather than via progressive scan as with most common spectrum analyzers. Real-time analysis is essential for observing intermittent or frequency-hopped signals. Sleeker, lighter weight, and quieter than their predecessor models, the R5550 and R5750 analyzers offer improved spectral performance, lower power consumption, and 
improved portability at a more cost-effective price over the previous R5500 models. The R5750 version adds an embedded GPS capability for time and location data, and comes with an optional IP66 rating for increased durability and ruggedness in challenging environments. Both are built for outdoor, mobile, and distributed deployment scenarios.
The portable, fanless ThinkRF R5x50 comes in 8, 18, or 27-GHz versions. They offer all the standard features of a sophisticated, expensive bench-top spectrum analyzer, but at far lower cost since they employ the display and processing power of an attached PC. Frequency controls, marker functions for tracking specific frequencies and multi-trace functionality are all included, as well as a real-time triggering for measuring complex data signals such as Wi-Fi and LTE. Sophisticated FPGA-based digital signal processing within the R5x50 enables the capture of elusive time-varying signals across an instantaneous bandwidth of up to 100 MHz.
Monitoring dynamic and agile signals usually requires a large budget instrument, but the R5x50’s advanced real-time spectrum analysis capability is no more expensive than an ordinary spectrum analyzer. The real-time analysis of the R5x50 design is based on patented, low-cost digital software-defined radio technology, open source software, standard APIs, and a PC-controlled architecture to provide unparalleled performance in an economical, portable instrument. The PC’s widescreen capability enables enhanced display options not available on benchtop instruments. Measurements can also be made remotely via the Internet for situations when monitoring personnel are not available.
Real-time spectrum analyzers excel at sensing signals that vary dynamically in amplitude or are agile in frequency, such as pulsed radar systems, frequency-hopping spread spectrum radios, and pulse modulated radios, multi-signal environments, or unwanted signals such as unintentional self-interference, intentional interference (jammers), and listening devices (bugs).
