2 Mobile Interference Hunting System Anritsu mobile interference hunting system is designed to automatically identify and locate sources of interferenceMaps provided on tablet/laptop provide directions to locate interference sources
3 Mobile Interference Hunting System Basic configuration for the Anritsu interference hunting system:MX280007A InterferenceHunterTM SoftwareAnritsu handheld spectrum analyzerOff-the-shelf omnidirectional magnet mount RF antenna with GPS (or use separate GPS antenna)Windows Tablet (recommended) or PC with Windows 7 or 8 operating system running the MX280007A softwareAntenna RAnritsu Handheld Spectrum AnalyzerWindows Tablet with Mounting Hardware
4 InterferenceHunter User Interface GPS positions car location on mapPower vs Time/PositionColored “breadcrumbs’ left along drive indicating power levels along driveGrey circle indicates probable interferer locationBreadcrumbs ‘Power v Color’ ChartUser Interface for mobile interference hunting system
5 Mobile Interference Hunting System Wide frequency range (9 kHz to 43 GHz possible)with appropriate Anritsu handheld spectrum analyzer and antennaCompatible with most existing Anritsu HH spectrum analyzers - (no firmware updates needed, GPS required)
6 Mobile Interference Hunting System Type of Interferers FoundLow powerNarrowband, widebandModulatedPulsed signals (similar to radar)Signals hidden in LTE uplink channels“Black” TV/radio stations & BTS cellular equipment operating illegallyChannel Power Measurements UsedTrack signals drifting in frequencyTrack both wideband and narrowband interferenceSpectrum Analyzer in Channel Power Mode
7 Mobile Interference Hunting System Shown with Anritsu Part No R AntennaMobile Interference Hunting System StartupConnect Spectrum Analyzer to tablet with USB cableSet analyzer RBW/VBW, Frequency, Channel BW, GPS ON, PreampLoad Map into MX280007A, adjust settings as neededStart the system and begin driving
8 Mobile Interference Hunting System Maps MX280007A works with both GoogleMapsTM and OpenStreetMapTMGoogleMaps requires an internet connection (a USB modem is typically used)Care must be taken so modem frequencies do not interfere with signals being huntedOpenStreetMap is downloaded to tablet/PC hard disk and imported into the interference hunting programMaps/Instructions for OpenStreetMap can be found here:Both mapping systems are open source and free of charge !
9 Special Features & Capabilities Interference within LTE uplink bands difficult to huntTraffic information often masks presence of interferenceAnritsu ‘Min Hold’ setting eliminates LTE traffics signals from measurement considerationComparison of LTE Uplink Band screenshots taken before and after MIN HOLD applied nInterferer obscured by LTE traffic on left can clearly be seen on screen on right
10 Other Features & Innovations Multi-emitter mode of operation, ideal for finding multiple leakage sources such as cable TVExtensive on-site Help MenuZoom In/Out controls providedFull-Screen Spectrum View on tabletVisual indicators show power levels along drive pathAbility to capture and store interference hunt log files for later playback and analysisSquelch Control to optimize hunting for low-level signalsVoice Prompts – enables one-person operation !
11 Finding CATV Interference CATV Leakage tends to occur at multiple locations in a neighborhood. Select ‘Multiple Emitter’ from ‘Mode’ tab.Enter Threshold level.Drive along various streets in the neighborhood.Multiple locations will be identified on map indicating positions of interference sources.Sample CATV Spectrum
12 Drive in area of interest. Spectrum ClearingIdentify areas where signals may exceed a user settable threshold Select ‘Spectrum Clearing’ from ‘Mode’ tab.Enter Threshold level.Drive in area of interest.Multiple locations will be identified on map showing threshold exceptions.
13 ‘Burst Mode’ Available for Receiver-like Speeds To find extremely fast signal pulses, Anritsu has developed “Burst Detect”Uses FFT technology to capture and process intermittent signalsCapable of 20,000 measurement per second, 15 MHz bandwidth… Entire span captured simultaneouslyAvailable on MS2720T Spectrum MasterTM, the MT8220T BTS MasterTM, and the MS203xC VNA MasterTM
