The Delta X system will make your bug sweeps quick and easy, while providing extremely reliable results. The system's hardware incorporates a powerful spectrum analyzer which provides a super-fast speed of measurements with extreme sensitivity, while the built in RF "switcher" extends the system's functionality.  Comes with a 2 hour introduction to Delta X video class for Free! 24/7 Monitoring  

Unlike conventional spectrum analyzers which require the individual inspection of each radio band depending on its assignment, the Delta X does everything automatically. The signals are recognized in the spectrum and depending on the type are saved in the "common" or "mobile & wireless" sections of the constantly updated list. Each signal is assigned an individual danger level, helping the operator to distinguish between safe external sources and suspicious local transmitters.
The great advantage of the Delta X is its high sensitivity and immunity to interference. While near-field receivers and detectors lose their sensitivity either significantly, or fully, near strong transmitters such as cellular towers, communication antennas, broadcasting stations, Wi-Fi access points, and wireless phones etc. the Delta X retains its ability to detect RF bugs at a significant distance.


Design Advantages

  1. Easily carry the Delta x G2 12  from room to room with the new Portable design

  2. Price point Delta X is an affordable Spectrum Analyzer

  3. Mount existing Laptop or tablet with use of provided magnetic holders

  4. Compatible with touch screens

  5. 24/7 monitoring with High capacity of a laptop or tables hard drive enables full data logging 

  6. Side handles for ease of carrying

  7. All antennas fixed to the main unit

  8. Unique to all Delta X built-in frequency library takes the "guessing out of sweeping"

  9. Operaters level of knowledge is no problem with the Delta X anyone can easily deployed using the "Update Mask" procedure. Everything is done automatically. After detections starts the operarator is warned by audio alarm when a dangerous signal is detected.
