The Marconi IFR Aeroflex 2026A is a multisource RF signal generator spanning 10 kHz to 2.05 GHz, designed for intermodulation, selectivity, and receiver testing in development and manufacturing environments. It integrates two independent RF sources into a single instrument, with optional third internal source and external generator connectivity. The unit delivers up to +24 dBm RF output and supports comprehensive modulation including AM, FM, phase modulation, 2FSK, 4FSK, and pulse modes. A built-in switched combiner network reduces measurement uncertainty by eliminating external cabling and connection losses.
