  • HISTOGRAM DISPLAY: The ANDRE features a signal strength histogram displaying RF levels over user-selected time intervals ranging from 5 seconds to 24 hours. Observe differences between digital, analog, and burst signals and set alert thresholds with audio and haptic feedback.
  • ZOOM VIEW: In zoom mode, only a 30 dB segment of the histogram is displayed. This reduced scale enables users to easily see small changes in RF signal activity.
  • SIGNAL INFORMATION AND BAND DETAILS: The ANDRE frequency counter automatically generates a signal list from the strongest signals. Signal frequencies are listed beginning with the strongest signal, and can be designated as threatening, friendly, or unknown. Double-tapping a signal provides more details including band classification information.
  • AUDIO MODE: The ANDRE can demodulate and playback live analog audio. Ten second audio files can be recorded, stored, and played back. The live audio screen displays a bar graph showing received signal strength.
  • DATA LOGGING (Deluxe feature): This new software feature provides histogram data for downloading to a PC and viewing on the ANDRE Data Viewer. Captured information includes time/date, signal amplitude, user settings, probes, chart duration and detailed frequency band information.

Post-Sweep Analysis Tools

REI’s DataViewer is a PC application that uses the Data Logging files from your ANDRE Deluxe to generate histogram charts. The information stored by the Data Logging feature includes time/date, signal amplitude, user settings, probes, chart duration, and detailed frequency band information.

Users can select to use Data Logging in three optional modes:

  • 250 hours and 500ms resolution
  • 25 hours and 50ms resolution
  • 30 minutes and 1ms resolution

The Data Viewer application paired with the Data Logging feature provides a powerful post-sweep analysis tool enabling users to keep and review sweep data even when they are no longer on location.
