The Marconi IFR Aeroflex 2305 Stabilock Tetra Test Set is a portable test instrument for characterizing Terrestrial Trunked Radio (TETRA) mobile stations and base stations in Professional Mobile Radio (PMR) networks. It operates across Trunked Mode (TMO), Direct Mode (DMO), Short Data Service (SDS), and Location Information Protocol (LIP), delivering modulation analysis, signal characterization, and receiver sensitivity measurement in field, installation, and maintenance environments.
