Mobile InterferenceHunter


Anritsu Mobile Interference Hunting System — Quick. Reliable. Multi-Emitter.

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 54 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™, and Remote Spectrum Monitor solutions. 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.

Anritsu Mobile Interference Hunting SystemQuick. Reliable. Multi-Emitter.

4G network operators have a strong interest in interference reduction driven by their customer’s adoption of an on-line lifestyle. The increasing demand for connectivity anytime and anywhere leads directly to the need to rapidly increase capacity and throughput.

Anritsu’s Mobile InterferenceHunter MX280007A, part of Anritsu’s monitoring and interference hunting family of products, can quickly and reliably locate interfering signals from a moving vehicle, even when there are multiple sources (think of a leaking CATV system) or when there are legitimate uplink signals present. It shines in difficult RF situations. Shadowing, multi-path, and reflections all can be sorted out. Pulsed or bursty signals can also be quickly found.

Key capabilities include:

  • Five minute setup in most vehicles, no need for a dedicated truck or van
  • Multi-emitter signal location for cases, such as CATV egress, where there are many signal sources.
  • Power-of-Arrival technique combined with averaging sorts out RF multi-path, frequency drift, shadowing, and reflections, allowing users to find the true signal source despite issues that confuse conventional direction finding techniques.
  • Area Scan™ techniques make signal location quicker and more accurate.
  • Post-capture analysis allows replaying of the drive, with different decision thresholds. This allows expert analysis, or even iterative analysis, of the drive data at a later time.
  • Simplified spectrum clearing, even with the uplink in service.
  • Can reliably locate many pulsed or bursty signals, even ones as short as 200 µS.
  • Uses a small magnet mount omnidirectional antenna for inconspicuous operation.

Tablet/Laptop Requirements

The Mobile InterferenceHunter MX280007A works with either the Windows 7, 8 or 10 operating systems. Windows 10 touchscreen tablets are preferred.

Minimum requirements for Windows tablet/PC:

  • Dual or Quad core processor (> 1 GHz)
  • 2 GB RAM
  • 32 GB onboard memory
  • Audio Jack

If the Spectrum Master MS2760A is being used, a USB 3.0 port is required. See the product brochure for details.

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™.

Users can develop their own map with OpenStreetMap using these simple to use instructions.

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.

Instructions for Making Maps

Use the OpenStreetMap web site to download your map. Once on the OpenStreetMap site:

  1. In the search box, located in the upper left, type in the city that you are looking for. Click on Go.
  2. After you you have selected the desired area from the displayed list, click "Export" located at the top left corner of the page above the search box.
  3. To the left of the screen, below the Export button, click on "Overpass API".
  4. The map data will be downloaded to your PC.

There are two ways to get the map into Mobile InterferenceHunter:

Click, drag, and drop the map file onto Mobile InterferenceHunter. The file will be converted and opened, ready for use. (Cannot drop on top of Google Maps.)


Open the downloaded map from the Mobile InterferenceHunter File menu.

  • From the main menu choose: Settings|Map Source|Open Source Maps.
  • Browse to your download folder.
  • Select 'OpenStreetMap archive' in the file type dropdown.
  • Find the file just downloaded and select Open.

When you open in Mobile InterferenceHunter software, a dialog box pops up to enter the city and country. Then the map is converted to our required format and opened in the software program.

The converted files are saved so that the next time you open that location, no additional formatting is needed.
