The new 2026 OSCOR Max Portable Spectrum Analyzer represents the latest upgrade to REI's professional portable spectrum analyzer lineup for TSCM and RF counter-surveillance applications. OSCOR Max is designed as the successor to OSCOR Blue and OSCOR Green, reflecting the growing need for wider frequency coverage and faster signal detection in modern RF environments.
OSCOR Max provides continuous spectrum coverage from 10 kHz up to 43 GHz, enabling detection of:
This wide coverage ensures reliable monitoring across both legacy and modern RF threats.
Compared to previous models, OSCOR Max offers significantly improved sweep performance, scanning the full 43 GHz frequency range at 25.6 times per second. This makes it well suited for detecting short-duration, burst, or intermittent transmissions that are often difficult to capture with conventional spectrum analyzers.

The system features fully integrated, auto-switching antennas covering the full frequency range, eliminating the need for manual antenna changes during a sweep.
A large 13.3-inch touchscreen display provides clear visualization of spectrum activity, spectrograms, and signal behavior, improving usability during field operations.
In addition to RF spectrum analysis, OSCOR Max supports advanced signal analysis functions such as:
The included Multi-Purpose Probe allows detection of certain non-RF threats such as infrared, ultrasonic, and more, extending its usefulness beyond classic RF sweeps.
OSCOR Max is a professional-grade instrument intended for qualified users and organizations who require the highest level of RF detection coverage and operational efficiency:
With the introduction of OSCOR Max, the previously available OSCOR Green and OSCOR Blue have been discontinued, making OSCOR Max the current portable OSCOR solution offered by REI. The new platform is intended for professional users who require extended frequency coverage, modern analysis features, and long-term product support.

Owning the most capable spectrum analyzer in its class means nothing if the operator cannot extract everything it offers. SpyShopEurope provides an exclusive two-day hands-on training course in Europe covering professional operation of both the REI OSCOR and REI MESA platforms in real-world TSCM scenarios.
By the end of the two days, participants will be able to independently operate both instruments, analyse RF spectrum data, and locate signal sources using structured professional methods ready to apply spectrum analysis as part of technical surveillance detection and wireless security inspections.
