Anritsu 69353A Synthesized Sweep/Signal Generator, 2 – 26.5 GHz

The Anritsu 69353A is a synthesized sweep/signal generator operating across 2 to 26.5 GHz, engineered for high-performance component and system evaluation in defense and telecommunications applications. It delivers stable, phase-locked output with fast frequency switching and minimal harmonic content. The instrument supports multiple sweep modes—CW, step, analog, manual, and alternate sweep—with flexible configuration across up to 10,000 steps. Internal modulation generators provide AM, FM, phase, and pulse modulation alongside user-downloadable complex waveforms. Five communication interfaces ensure seamless integration into automated test environments.
