The Anritsu MG3692A is a synthesized signal generator delivering precise RF and microwave signal generation from 10 MHz to 20 GHz. Built for demanding test environments, it combines broad frequency coverage with fine-resolution control, multiple modulation modes, and exceptional phase noise performance. Engineers rely on it for component characterization, system validation, and production testing across commercial and defense applications.
