Coverage Mapping is possible both outdoors (GPS signal required) and indoors (no GPS signal). For more accurate position data for indoor measurements, use a stylus such as the Anritsu 2000-1691-R.
• Outdoor Mapping: The instrument logs data automatically based on either time or distance interval. If there is no map available when making the measurements, it is still possible to save all the data to a KML file and then combine the data with a map. You may also recall a map after taking the data without having to save and recall it.
• Indoor Mapping: Using a start‑walk‑stop approach, the instrument provides in‑building coverage mapping by overlaying data directly onto the downloaded map (which may be a drawing of a building). Data is captured when you tap the touch screen. The instrument places points linearly between taps if Time interval is used for capturing data and there is more than one measurement. When the Repeat Type is Distance, new measurements are placed at the next tap point.
Outdoor Coverage
With a valid GPS signal, the instrument identifies the current location on the displayed GeoEmbedded map with a plus sign. Previously saved locations are displayed as squares. Using GPS, latitude, longitude, and altitude data is automatically saved for each location.
Outdoor Coverage Mapping (GPS On)
Note
The Measurement Setup and Threshold Setting boxes can be used as menu shortcuts on touch screen instruments.
Use the touch screen to select the parameter to edit.
Indoor Coverage
With GPS turned off and a non‑GeoEmbedded map file, the user indicates the current position (+) with the touch screen. On instruments that do not have a touch screen, use the arrow keys. Previously saved locations are displayed as squares.
Anritsu easyMap Tools allows you to capture maps of any location and create Anritsu Map Files. These maps are used for Coverage Mapping and Interference Mapping (Interference Analyzer (Option 25)). There are two Anritsu Map File formats:
• legacy .map map files
• .azm map files, which are displayed in full zoom-out view (Coverage Mapping pan-and-zoom is currently supported on the LMR Master S412E only)
Type an address in easyMap Tools and capture the map with GPS data.
Indoor Map
In easyMap Tools, open a bitmapped image (JPEG, GIF, TIFF, or PNG) of the floor plan for indoor mapping. You can also use a downloaded map and make it an indoor map. This method works well if you can get a good aerial view of a building.
The image size should be close to 666 pixels x 420 pixels (approximately 1.6:1 ratio).
Note
A USB flash drive is required to transfer maps to the instrument.
Instrument Settings
Setup
1. Create the appropriate map with easyMap Tools. Refer to Anritsu easyMap Tools and the software Help. Outdoor mapping requires a GeoEmbedded map or the default grid.
2. Open up Coverage Mapping by pressing the Menu key and selecting the Spectrum Analyzer icon or press Shift then Mode (9), highlight Spectrum Analyzer and press Enter.
3. Press Shift then Measure (4). Press the Coverage Mapping submenu key. Confirm that coverage mapping is On. On or Off is underlined on the submenu key in the Coverage Mapping menu.
d. Turn on GPS. On should be underlined in the GPS submenu key.
e. Press the GPS Voltage submenu key to select the appropriate voltage for the antenna being used. Refer to the instrument Technical Data Sheet for voltage specifications of supported GPS antennas.
f. Press GPS Info and verify that the information from four or more satellites is captured. Press Esc to close the info box.
It may take several minutes for the GPS receiver to track at least four satellites. When it does, the GPS icon at the top of the screen turns green. Refer to your instrument User Guide for additional information on GPS.
Recall a Map (Indoor or Outdoor Coverage)
The instrument allows you to recall a .map file or .azm file created with easyMap Tools. With a valid GPS signal, the current location will be displayed on an outdoor map or an arrow will show the direction of the current location if it is outside the map coverage area. With an indoor map, position the plus sign at the current location by using the touch screen or by using the arrow keys and then pressing Enter.
Connect the USB flash drive that has the map file or files created in Anritsu easyMap Tools to the instrument.
1. Press the Coverage Mapping submenu key.
2. Press the Save/Recall Points/Map submenu key.
3. Press Recall a Map and select the appropriate map from the USB flash drive.
4. Use the arrow keys to scroll down to the desired map and press Enter to select.
5. The new map file will be displayed and the current location (if within the GPS boundaries of the displayed map) is shown as a plus sign with outdoor mapping.
6. If the current location is outside the map boundaries, an arrow indicates the direction of the current location in relation to the displayed map.
If you do not see the USB drive in the Recall menu:
1. Press the Refresh Directories submenu key.
2. If the drive is still not visible, exit the menu, then remove and reconnect the USB drive.
3. Press Recall a Map again.
4. If the drive is still not visible, reformat the USB flash drive in FAT32 format, then copy the map files to the reformatted drive.
Recall the Default Grid
The instrument can make coverage mapping measurements even when an Anritsu easyMap Tools file of the current indoor or outdoor location is not available. In such cases, use the default grid map, save the KML points, and recall them at a later time with a map. You may also recall a map after taking the data without having to save and recall it. Alternatively, you can save the KML points and view them in Google Earth or Google Maps, or you can save the points in mtd (mapping tab delimited) format, and use another tool for analysis, such as Microsoft Excel. Refer to Mapping Save/Recall Menu for additional information on recalling saved maps and .kml data.
Note
When using the default grid, the coverage area for outdoor mapping is fixed at 10 x 10 miles. For indoor mapping, the grid size is the indoor map file dimensions (666 pixels by 420 pixels; or 0,0 to 665,419). If GPS is on and locked, the center point of the default grid is the current location when the Recall Default Grid button was pressed.
1. Press the Coverage Mapping submenu key.
2. Press the Save/Recall Points/Map submenu key.
3. Press the Recall Default Grid submenu key.
Coverage Mapping with the Default Grid.
Map the Signal Strength
Coverage Mapping supports RSSI measurement or ACPR measurement during mapping.
Note
The default settings for coverage mapping set the internal input attenuator to 0 dB (off) with the preamp on and a bandwidth of 1 MHz. These parameters can be adjusted depending on the strength of the signal being measured. The bandwidth is 10 kHz for RSSI measurements. For ACPR, it is based on ACPR settings (channel width and spacing) and the resultant span, as well as if Auto RBW is set.
Overdriving the input of the spectrum analyzer can result in ADC Overdrive or Saturation errors. Refer to Indications of Excessive Signal Level. If necessary, make adjustments using the Amplitude menu and BW menu.
Once data collection begins, parameters such as amplitude, bandwidth or measurement setup cannot be changed.
ACPR
1. Press the Coverage Mapping submenu key.
2. Press the Measurement Setup submenu key.
3. Set the Center Freq, RBW, and Detection type. Refer to Spectrum Analyzer for additional information.
4. Press ACPR once to select and again to open the setup menu.
a. Enter the Main and Adjacent Channel Bandwidths.
b. Enter the Channel Spacing.
c. Enter Good Passing Criteria and the Poor threshold level.
d. The main channel power indicator in the bottom part and the data collection squares will display colors as shown below:
Red Value (Poor) < Yellow Value < Green Value (Good)
5. Press the Start Data Collection main menu key. Data will be collected at the time or distance interval based on the setting in Point Distance/Time Setup Menu. The color of the squares indicates the power level based on ACPR setup.
You may have to move the instrument around, and for indoor maps, you may need to tap the touch screen.
6. Press the Stop Data Collection main menu key. Save the collected data as a .kml file, a tab‑delimited text file (.mtd) or a .jpg file. Refer to Mapping Save/Recall Menu.
Note
The collected data can be saved in multiple formats.
