The LMR Analyzer Coverage Mapping options provide the ability to measure and map signal strength, modulation fidelity, error vector magnitude, or bit error rate of a single channel as a function of time and location. These options are not to be confused with Option 431 Coverage Mapping, which is a legacy option that applies only to the Spectrum Analyzer mode.

The LMR Master combines the received signal information with time and location information from the internal GPS module (Option 31 required) to store data that can then be turned into coverage maps using third party software.

The easyMap Tools™ program creates single panel maps (.map) that are compatible with Anritsu’s handheld instruments. The software also creates pan and zoom maps (.azm) that are compatible with supported Anritsu instruments. The software imports maps from OpenStreetMap and Google Maps and creates files with or without GPS information. Anritsu easyMap Tools is available from the Anritsu Web site: www.anritsu.com.

When Start Data Collection is turned On, OTA measurements are attached to the GPS location and time data, and the measurements are saved to a file. Captured data can be saved as a tab delimited text file (.mtd) for viewing coverage data in a spreadsheet, text editor, or third‑party coverage prediction software. The measurements can also be saved in.kml format for direct viewing with mapping software, such as Google Earth.

For P25/P25p2, NXDN, dPMR, TETRA, DMR, and PTC Coverage (both ITCR and ACSES), the measurement information that is collected includes Received Signal Strength Indication (RSSI), Bit/Message Error Rate (BER/MER), and Modulation Fidelity (in TETRA and PTC, RMS Vector Err (EVM) replaces Modulation Fidelity). NBFM Coverage includes RSSI, Total Harmonic Distortion (THD), Signal‑to‑Noise and Distortion ratio (SINAD), and External SINAD.
