The Marconi IFR Aeroflex 2052 is a digital and vector signal generator engineered for RF testing across modern digital communication systems. Operating from 10 kHz to 5.4 GHz, it delivers complex modulation formats through internal DSP processing, with dedicated digital and vector modes supporting frequencies up to 2.7 GHz. The instrument provides analog modulation (AM, FM, PM), digital modulation (FSK, PSK, DPSK, QAM up to 256-level), and vector I/Q modulation with typical errors below 0.5%.
