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 later combine the data file with a map.
Note
Coverage mapping requires Option 31 or an Anritsu analyzer having the GPS receiver as a standard accessory.
Coverage Mapping
With a valid GPS signal, the instrument will identify the current location on the displayed GeoEmbedded map with a cross. Previously saved locations are displayed as squares.
Anritsu easyMap Tools allows you to capture maps of any location and create an Anritsu Map File. These maps are viewed on the Anritsu instrument during coverage mapping. There are two Anritsu Map File formats:
• legacy .map map files
• .azm map files (not currently compatible with Coverage Mapping)
Download easyMap Tools from the Anritsu website (www.anritsu.com). Additional information about easyMap Tools is available in the software Help.
Note
A USB flash drive is required to transfer maps to the instrument.
Instrument Settings
Setup
1. Create the appropriate map with Anritsu easyMap Tools. Refer to Anritsu easyMap Tools. Mapping requires a GeoEmbedded map or the default grid.
2. Open up Coverage Mapping by pressing the Measurements main menu button followed by pressing the Over‑the‑Air submenu key and then pressing the Mapping submenu key.
3. Turn on GPS.
a. Press Shift then System (8).
b. Press the GPS submenu key.
c. Connect a GPS antenna to the SMA connector.
d. Turn on GPS. On should be underlined in the GPS submenu key.
Note
For all instruments with using an SMA connector, the GPS antenna voltage is selectable between 3.3 and 5 VDC. Set the proper voltage for the GPS antenna in use.
e. Press GPS info and verify that the information from three 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 three satellites to obtain longitude and latitude coordinates. Tracking 4 satellites will obtain altitude information. The GPS icon at the top of the screen will turn green when the instrument is receiving GPS data. Refer to the User Guide for your instrument for additional information about GPS.
Recall a Map
The instrument allows you to recall a .map file (created with Anritsu easyMap Tools). With a valid GPS signal the current location will be displayed on the map or an arrow will show the direction of the current location if it is outside the map coverage area.
Connect the USB flash drive that has the map file or files created in Anritsu easyMap Tools to the instrument.
1. Press the Mapping submenu key in the Over‑the‑Air submenu.
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 cross on the map.
6. If the current location is outside the map boundaries, an arrow will indicate the direction of the current location in relation to the displayed map.
Note
If you do not see the USB drive in the Recall menu:
1. Press the Refresh Directories key. 2. If the drive is still not visible, remove and then reconnect the USB flash drive. 3. Reformat the USB flash drive and copy the map files to the reformatted drive.
Recall the Default Grid
The instrument is able to make coverage mapping measurements even when an Anritsu easyMap Tools file of the 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. 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 mapping is fixed at 10 x 10 miles.
1. Select the Mapping submenu key.
2. Press the Save/Recall Points/Map submenu key.
3. Press the Recall Default Grid submenu key.
LTE Coverage Mapping with the Default Grid.
Measurement Setup
1. Press the Measurements main menu key.
2. Press the Over‑the‑Air submenu key.
3. Press the Mapping submenu key to activate the Coverage Mapping display. Press the Mapping key again to display the Coverage Mapping menu.
4. Press the MeasurementSetup submenu key to open the Measurement Setup menu to select which measurement is mapped and to set the threshold values for S‑SS, RSRP, RSRQ and SINR.
5. Press the Measurement submenu key to open the Mapping Parameter menu.
a. Select the signal parameter to be mapped and displayed in bar graph form by selecting one of the parameter buttons and then pressing Back. All four measurements are saved for each data point, independent of which one is chosen for mapping on the instrument screen. For example, if RSRP is selected for mapping, the resulting .kml file will also include S‑SS, RSRQ and SINR values.
b. Set the thresholds for S‑SS, RSRP, RSRQ or SINR by pressing the respective Thresholds button. After pressing a threshold button, set the threshold levels for Excellent, Very Good, Good, Fair and Poor. Then press the Back button.
6. Set up the interval type and interval parameters. Press the Point Distance/Time Setup submenu button to open the Points Distance/Time menu. If Time is selected for Repeat Type, then set the time period by pressing the Repeat Time submenu key. If Distance is selected for Repeat Type, then set the Repeat Distance and Distance Units. If necessary delete any previously stored points by pressing the Delete ALL Points button.
Note
All files will be stored in the default save location. To change the default location, Press Shift then File (7) to enter File menu. Press Save then Change Save Location. Create a new folder or change the current location on the USB flash drive or in the instrument’s storage memory. Press Set Location to make this the new default location for saving files.
7. Press Back to return to the Over‑the‑Air menu.
Measurement Mapping
After completing the setups for Coverage Mapping and measurements, you are ready to make measurements.
1. 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 the chosen measurement and its threshold level setup.
2. Press the Stop Data Collection main menu key to end the measurement process. Save the collected data as a .kml file, a tab‑delimited text file (.mtd) or a .jpg file. Refer to Save the Coverage Mapping Information.
Press Save/Recall Points/Map then Save KML Points. At the Save menu, press Enter. The following information is saved for the points currently displayed on the screen:
2. Click Download Google Earth and follow the on‑screen instructions.
3. After download, install Google Earth on your computer.
4. Double‑click on the saved .kml file to view the measurements in Google Earth.
After Google Earth is opened, user instructions and several types of help are available from the Help pull‑down menu.
Saved .kml files cannot be viewed directly from the instrument using Google Earth, the files need to be first copied to a USB memory stick.

Save Tab Delimited Points
Press Save/Recall Points/Map then Save Tab Delimited Points. At the Save menu, press Enter. A tab delimited text file (.mtd) will be saved in the default save location for the coverage mapping data currently displayed on the screen.
Note
All files will be stored in the default save location. To change the default location, Press Shift then File (7) to enter File menu. Press Save then Change Save Location.
