The Anritsu 68367C is a synthesized signal generator delivering precise, stable RF signals from 10 MHz to 40 GHz for advanced microwave test applications. It combines ultra-low phase noise, wide dynamic range output control, and sophisticated modulation capabilities—making it ideal for satellite, radar, and telecommunications system characterization. The instrument supports multiple sweep modes, complex signal generation, and flexible leveling accuracy down to –120 dBm, enabling demanding receiver sensitivity and radar blind spot testing scenarios.
