OSCOR Green Spectrum Analyzer

Portable RF Detection & Analysis

The OSCOR Green 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. The OSCOR Green is a portable spectrum analyzer that sweeps 24 GHz in one second to quickly detect transmitting electronic surveillance devices and ensure that spectrum activity is captured.

Efficiency:  reference and target traces are quickly attained, stored, and compared for rapid analysis and a waterfall display generates a spectrogram of receiver traces over time

Usability:  employs a touch screen interface, remote access capabilities, and built-in software

Portability:  weighs less than ten pounds and does not require additional antennas or cables; battery power lasts 3-4 hours

OSCOR Data Viewer logo

The Data Viewer Software allows OSCOR Blue and OSCOR Green users to be open, view, analyze, organize, export and print saved data files on a PC.

The Data Viewer works with the following file types:

  • Trace files – Peak or Average trace files display in a graph view with zoom and scroll capability. Multiple trace files can be layered in one graph view for comparison.
  • Signal Lists – displays frequency, bandwidth, amplitude, and date. Can be exported to csv or html file format for further analysis.
  • Images – displays screenshots, raster waterfall and other images.
  • Audio files – demodulated audio selected in the software will launch default media player to play back audio.
  • Can analyze OSCOR Blue Trace Record Waterfall or OSCOR Green Spectrogram files.

Download the Data Viewer software and run installation on a Windows XP, Vista, 7, 8, or 10 Operating System. Microsoft .Net Framework Version 4 may also be required. From the OSCOR, .peak, .avg, .png, .wav and .signals files can be saved to the Compact Flash or a USB device and then transferred to the PC. From the File/Open menu, select the desired files to open. A Quickstart guide is available in the Help menu.
