The Marconi IFR Aeroflex 3414 is a digital RF signal generator engineered for precision signal generation from 250 kHz to 4 GHz. It delivers output power up to +16 dBm with exceptional spectral purity and supports analog, vector, and digitally modulated signals. Built for research, development, manufacturing, and high-speed automated test equipment (ATE), it combines fast settling times with flexible modulation architectures.
