The Marconi IFR Aeroflex 2032 is a wideband signal generator delivering precise RF signal generation from 10 kHz to 5.4 GHz. It supports AM, FM, and phase modulation with optional pulse capability, making it suitable for RF component characterization and radio communications system testing. The instrument features 0.1 Hz frequency resolution, output power spanning -144 dBm to +13 dBm, and multiple modulation modes including single, dual, and composite configurations. A dot matrix LCD with backlighting provides intuitive operation, while standard GPIB (IEEE 488.2) enables remote automation.
