The Marconi IFR Aeroflex 2965 is a radio communications test set engineered for signal generation, analysis, and measurement across the 100 kHz to 1 GHz band. Built for R&D, production, and field maintenance of radio transceivers and communication systems, it combines a high-performance signal generator, dual-domain spectrum analyzer, RF power meter, and digital storage oscilloscope in a single integrated platform.
