The Marconi IFR Aeroflex 2040 is a microprocessor-controlled signal generator spanning 10 kHz to 1.35 GHz, engineered for RF circuit characterization, communication system testing, and general-purpose signal synthesis. The instrument delivers +13 dBm output standard, with +19 dBm available via Option 003. Its modulation suite includes AM, FM, phase modulation, and FSK, plus optional pulse modulation. Internal and external modulation sources support frequencies from 0.1 Hz to 500 kHz via independent dual inputs with automatic leveling control.
