The Anritsu S412D LMR Master is a handheld instrument that consolidates cable and antenna analysis, spectrum monitoring, power measurement, and modulation analysis into a single field-deployable device. Designed for LMR and Public Safety technicians, it performs RF diagnostics, interference detection, and transmitter verification for P25, NXDN, and iDEN systems without requiring multiple specialized tools.
