Selecting the Mode
Select the desired type of interference hunt that is going to take place. Switch modes during or after acquisition, for further analysis.
Scan Driving (Initial Perimeter Survey)
Use this mode to search for an interferer in a general area. This mode works well with the View set to Heat Map. The dark lavender shaded area on the drive map indicates an approximate area where the interferer could be. Once an interferer’s general location has been determined, refer to Creating a Drive Route to hone in on the signal in this area.
Spot Driving (Standard Operation)
Hunting for a single interfering signal.
Multiple Emitter
Hunting for multiple interferer transmitters such as cable TV leakage.
Spectrum Clearing
Hunting for multiple transmissions of the same frequency whose power exceeds the threshold set by the user. Screen images can be automatically saved when the threshold is exceeded.
Time Difference of Arrival (TDOA)
Use TDOA to locate interference sources and other modulated broadcasters. TDOA is not a driving mode like the other modes mentioned above. For TDOA, you must have access to at least three remote spectrum monitor probes (MS2710xA). Refer to Setting Up TDOA when using this mode.
Selecting the Map Source
Click a map from the map sources to use in the map display. For more on loading maps, see Loading Maps.
Google/Baidu Maps
The Google/Baidu map will identify the vehicle’s current location and display the map for that area.
Open Source Maps
Open a folder where Open Source maps are saved. Click any .shp file and then Click Open to load the map. Depending on the coverage area or the number of locations that are tested for interfering sources, multiple maps may need to be downloaded onto the tablet or laptop. Click a map from a map source to use in the map display – Google/Baidu map or a map from any open source map. See Product Information and Map Services in the Help Menu.
