The Anritsu MG3694B is a synthesized signal generator delivering 2 GHz to 40 GHz frequency coverage with 0.01 Hz resolution. Purpose-built for RF and microwave R&D, manufacturing, and depot repair, the instrument combines broad frequency range, high spectral purity, and exceptional stability in a single platform. Every frequency step within sweep range is phase-locked, enabling precise characterization of complex high-frequency systems.
