Models available

  • 8 GHz Model (OBL-8) : 10 kHz to 8 GHz

  • 24 GHz Model (OBL-24): 10kHz to 24 GHz


The OSCOR Blue is a portable spectrum analyzer with a rapid sweep speed and functionality suited for detecting unknown, illegal, disruptive, and anomalous rogue transmissions across a wide frequency range. The OSCOR Blue Spectrum Analyzer is designed to detect illicit eavesdropping signals, perform site surveys for communication systems, conduct radio frequency (RF) emissions analysis, and investigate misuse of the RF spectrum.
Efficiency: sweeps 24 GHz in one second to quickly detect transmitting electronic surveillance devices and ensure that spectrum activity is captured
Usability: captures comprehensive signal activity without missing signals due to limited antenna range or from having to switch external antennas
Portability: complete integrated spectrum analyzer system with built-in antennas and analysis software, small and hand-held for easy mobility

  • OSCOR Blue sweeps 24 GHz in 1 second in 12.2 kHz steps. Fast sweep time, built-in antennas, and on-board software make the OSCOR Blue easy and quick to deploy, optimizing total operational speed.

  • Seamless real-time spectrum visibility from 10 kHz to 24 GHz or 10 kHz to 8 GHz (depending on the model) using the integrated auto-switching multi-antenna system.

  • The OSCOR Blue is lightweight (9.6 lbs./4.4 kg), small and hand-held for easy mobility through target areas while collecting trace data.

  • REI’s trace analysis functionality adds dimension by providing full analysis of trace data on-board. Perform trace analysis on-screen without the need for a laptop.

  • OSCOR Blue can subtract a reference trace from a target sweep trace, and then create a signal list from the difference trace, very quickly showing a list of signals unique to the target area.

  • Waterfall analysis captures and records signal peak traces over time for historical analysis of spectrum activity.

  • Signals are easily located based on RSSI level change and near field locating function.

  • Continuous spectrum update while using built-in suite of demodulators (audio, video).

  • OSCOR Blue includes a Multi-Purpose Probe that plugs into the Auxiliary port for capturing carrier current, IR, CATV (F Connector), VLF Antenna.
