The Marconi IFR Aeroflex 2967 is a radio communications test set engineered for comprehensive testing and alignment of cellular, trunking, and FM radio equipment across production and field service environments. It integrates a spectrum analyzer, tracking generator, signal generator, and power meter into a single platform, enabling full transmitter and receiver characterization across GSM, AMPS, TACS, NMT, and MPT trunking standards.
