The Anritsu MG3693A is a synthesized signal generator delivering precise frequency synthesis across 2 to 30 GHz with optional coverage extending to 0.1 Hz via Direct Digital Synthesizer (Option 22). The instrument combines exceptional spectral purity, broad modulation support, and flexible sweep modes to meet demanding requirements in RF/microwave component characterization, system validation, and advanced signal simulation.
