2. Press the Measurement main menu key, then the Coverage submenu key (press the Coverage submenu key a second time if necessary to display the Coverage Mapping menu). The Display Type may be Map or Graph. Press the Display Type submenu key to toggle this setting.
3. Select the signal parameter to be mapped and displayed in bar graph form by pressing Mapping Type.
For P25, NXDN, and DMR, coverage, select RSSI, BER, or Mod Fid; for PTC (ITCR and ACSES) select RSSI, BER, or EVM.
RSSI displays the Received Signal Strength Indicator of the received signal.
BER displays the bit error rate of the received signal. The BER is measured against the Rx Pattern and Mod Type selected under the Setup main menu.
Mod Fid displays the modulation fidelity of the received signal.
For dPMR coverage, select RSSI.
RSSI displays the Received Signal Strength Indicator of the received signal.
For TETRA coverage, select: RSSI, BER, or RMS Vector Err (EVM).
RSSI displays the Received Signal Strength Indicator of the received signal.
BER displays the bit error rate of the received signal. The BER is measured against the Rx Pattern and Mod Type selected under the Setup main menu. Note that BER measurements are only valid for Base Station measurements.
RMS and Peak Vector Err (EVM) is a measure of how far the constellation points are located from the ideal positions. EVM is measured against the Rx Pattern and the Mod Type selected from the Setup main menu.
For NBFM coverage select: RSSI, THD, SINAD, or External SINAD.
RSSI displays the Received Signal Strength Indicator of the received signal.
THD displays the total harmonic distortion.
SINAD and External SINAD displaysignal‑to‑noise and distortion ratio.
Note
RSSI values are offset by any Rx Power Offset setting (Amplitude menu).
4. All measurement values are saved for each data point, independent of which signal parameter is chosen for mapping on the instrument screen. For example, if RSSI is selected for mapping, then the resulting .kml file also includes BER and Mod Fid values.
5. Press the LegendSetup submenu key to set the threshold values for the selected measurement. Set the threshold levels for Excellent, Very Good, Good, Fair, or Poor. Then press the Back button.
6. Set up the interval type and the interval parameters. Press the Point Distance/Time Setup submenu key 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 press Change Save Location. Create a new folder or change the current location on the USB flash drive or in the instrument storage memory. Press Set Location to make this the new default location for saving files.
7. Press Back to return to the Coverage Mapping menu.
