The Anritsu 69177A is a synthesized sweep generator delivering precision microwave signal generation across 0.01 GHz to 50.0 GHz. Built for automated test systems and component characterization, it combines fast frequency switching with ultra-low phase noise in a single, cost-effective instrument. The 69177A anchors Anritsu’s El Toro synthesizer family, with related models extending coverage to 65 GHz and waveguide options to 110 GHz.
