  • 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 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.
