Mobile InterferenceHunter


Anritsu Mobile Interference Hunting System - “Interference Hunting Made Easy”

The key elements are an Anritsu spectrum analyzer, a magnet mount omnidirectional antenna, a Windows® tablet and the MX280007A Mobile InterferenceHunter Software with the following features:

  • Start rolling quicker and find interference faster than any other solution with less than 5 minute set-up, user-friendly operation, and powerful patent-pending software algorithms.
  • Follow direction indicators on map to locate interference source.
  • See a map view showing the driven route with signal strength markers along with position estimates of the interferer all on a dash-mounted tablet PC.
  • Special features allowing users to detect interferers in LTE uplink bands, periodic (or pulsed) signals and wideband interferers.
  • Voice prompts direct the driver to the estimated interference location for safe one-person operation.
  • Utilize a small magnet mount omnidirectional antenna for inconspicuous operation at the desired frequency of interest within the range of the spectrum analyzer.
  • Drive close enough to be within walking distance of the interference to pinpoint the source with our MA2700A Handheld InterferenceHunter Solution with a directional antenna.

Anritsu Mobile Interference Hunting System - “Interference Hunting Made Easy”

Wireless networks today are being impacted by interference that degrades network performance. For wireless service providers, issues such as dropped calls, blocked calls, and data throughput are all impacted negatively by harmful interference. Operators need to utilize the full of capacity of their networks to keep up with demand. Interference must be found quickly with a tool that is fast and simple to use by even inexperienced RF maintenance technicians. The Anritsu Mobile Interference Hunting System delivers on the requirement for fast and simple interference hunting.


Anritsu’s Mobile InterferenceHunter MX280007A is a quick and reliable way to find single or multiple sources of interference. The ability to work with multiple signal sources, reflections, RF shadows, drifting signals, bursty signals, and multi-path distinguish the Mobile InterferenceHunter MX280007A from more expensive solutions targeted at single fixed frequency interference sources.

The Mobile InterferenceHunter’s post-capture analysis capability allows users to modify search parameters without re-driving the route. This allows re-analysis of the captured data as well as consulting with experts.

The Mobile InterferenceHunter works with the broad array of Anritsu’s handheld spectrum analyzers, providing interference hunting and spectrum clearing capability from 9 kHz to 110 GHz. The Mobile InterferenceHunter is a quick, reliable, and multi-emitter enabled solution to your interference hunting and spectrum clearing needs.

Sample Mobile InterferenceHunter System Components

For a full description of the Mobile InterferenceHunter MX280007A, please see the product brochure, available under the Library tab.

By utilizing Anritsu’s proprietary interference finding algorithms, the Mobile InterferenceHunter MX280007A software will quickly determine the position estimate of an interfering signal. Once sufficient measurements are accumulated in Area Scan™ mode, the Mobile InterferenceHunter MX280007A software can create a heat map indicating the position of the interference source. The heat map becomes smaller as more measurements are taken, refining the signal location estimate.

With a user interface optimized for Windows touchscreen tablets the MX280007A software is simple to use. Features include:

  • Max Hold to find interferers which show up periodically (i.e. “radar type” signals)
  • Min Hold to find interferers buried underneath the intended signal (ideal for finding signals hidden in LTE uplink bands)
  • Squelch Control to view only signals above a certain threshold
  • Sensitivity settings from Dense Urban to Rural terrain categories
  • Area Scan mode to quickly localize the signal source
  • Choice of map sources: Google Maps, Baidu Maps, or OpenStreetMap
  • Zoom In/Out commands for desired street level view
  • Full Screen Spectrum View for better examination and analysis of the spectrum
  • Growing Breadcrumbs of the drive route that indicate higher signal strength as you drive closer to the interference source
  • Single or multiple emitter detection modes make it easy to use for any type of emitter detection application (multiple emitter mode is ideal for locating multiple cable TV interferers)
  • A spectrum clearing mode using channel power measurements that map signals above a certain power threshold
  • Integrated help system for user assistance

The Anritsu Mobile InterferenceHunter MX280007A works with many existing Anritsu handheld spectrum analyzers that are enabled with a GPS receiver. These include platforms such as Site Master™, Spectrum Master™, BTS Master™, Cell Master™, LMR Master™, Remote Spectrum Monitor, and the Spectrum Master MS2760 Ultraportable solution. No firmware updates are needed.

The Anritsu Mobile InterferenceHunter solution is designed to be best-in-class for its interference detection capability and ease of use. No other inference hunting system is as efficient and simple to use with easy set-ups for safe one-person operation.

The Anritsu Mobile Interference Hunting System is designed to locate interference signals operating anywhere in the frequency band covered by the spectrum analyzer. An off-the-shelf magnet mount omnidirectional antenna whose range covers the frequencies of interest is required.

Some examples of interferers include but are not limited to the following:

Intentional Radiators

  • Cell jammers
  • Improperly installed repeaters
  • Oscillating bi-directional amplifiers
  • Wireless devices working in improper bands
     – Baby monitors
     – Microphones
     – Surveillance Cameras
  • Pirated cell phones
  • Illegal or "black" base stations

Unintentional Radiators

  • External PIM
  • Cable TV systems
  • Fluorescent lighting
  • Arc welders
  • Industrial microwave
  • Industrial RF heaters
  • Outdoor elevator motors

Maps used for the interference hunting software can be embedded in the application using OpenStreetMap™. Anritsu provides a webpage to aid the user in this process:

Anritsu Mobile InterferenceHunter Maps

Users can choose an already developed map from the selection provided on the Maps page. Alternatively, one can develop their own map with OpenStreetMap using the simple to use instructions provided.

Once maps are made, they can then be incorporated into the MX280007A software by dragging the map file on to the interference hunting software application window. Maps can also be added by clicking on the Settings tab at the top of the MX280007A software and selecting Map Source/Open Source Maps.

Alternatively, tablets with cellular modems attached for internet access can download Google Maps or Baidu Maps for their application.

For full instructions on how to get up and running, use the Mobile InterferenceHunter User Guide located in the Library tab.
