The Marconi IFR Aeroflex 3412 is a digital RF signal generator spanning 250 kHz to 2 GHz, engineered for RF testing, development, and maintenance across wireless communication systems. It delivers +16 dBm peak output with 0.01 dB resolution and includes vector modulation up to 55 MHz bandwidth, analog modulation (AM to 30 MHz, FM to 20 MHz), phase modulation to 10 radians, and optional pulse and FSK capabilities. Spectral purity reaches 1.5 Hz residual FM at 1 GHz with noise floor better than -148 dBc/Hz. The instrument features fast settling times, optional List Mode for frequency hopping (<500 µs), and multiple RF optimization modes. High-stability OCXO frequency standard and reverse power protection are included.
