The Anritsu 69369A is a synthesized sweep/signal generator delivering precision signal generation from 0.01 GHz to 40 GHz in a single coaxial output. It combines ultra-low phase noise, wide dynamic range, and advanced modulation capabilities to serve telecommunications, research, and electronics testing applications. The instrument supports multiple sweep modes, internal and external modulation, and integrates with network analyzer systems for comprehensive signal characterization across microwave and millimeter-wave frequencies.
