The Anritsu 68397B is a synthesized sweep/signal generator delivering precise RF signal generation across 0.01 GHz to 65 GHz. Built for telecommunications, aerospace, defense, and microwave R&D, it combines low phase noise, stable output power, and flexible sweep capabilities to characterize components, sub-assemblies, and complete systems. The instrument supports frequency and amplitude sweeps, step and list modes, with user-selectable sweep times from 1 ms to 1000 s and triggering options including internal, external, manual, and line.
