3-10 PN: 10580-00349 Rev. H Spectrum Analyzer MG
Interference Mapping (Antenna Only)
1. Capture a map using Anritsu easyMap Tools.
Anritsu easyMap Tools allows you to capture maps of any location and create Anritsu Map
Files. These Geo-enabled maps are viewed on the Anritsu instrument during interference
mapping. There are two Anritsu Map Files formats: (.map and .azm) used for Interference
Mapping.
• .azm map files allow Pan and Zoom on the instrument.
• .map map files are in a legacy format compatible with older firmware.
Download easyMap Tools from the Anritsu website ( www.anritsu.com ). Additional
information about easyMap Tools is available in the software Help.
2. Move the map file to the Anritsu instrument.
Copy the map file to a USB memory stick and then insert the memory stick into the Anritsu
instrument’s USB Type A port. Anritsu recommends copying the map file to the instrument’s
internal memory. Refer to Anritsu instrument User Guide for additional information.
