MG3694B

The Anritsu MG3694B is a high-performance synthesized microwave signal generator covering the 2 GHz to 40 GHz frequency range. Belonging to the renowned MG3690B series, it provides outstanding output power, exceptional phase noise performance, and highly versatile modulation capabilities (including AM, FM, phase, and pulse). Designed for demanding RF and microwave applications, it serves as an ideal local oscillator or signal source in automated test equipment (ATE) systems, radar testing, and communication system characterization. It is fully backward compatible with the MG3690A and previous 68C/69B series synthesizers, and features a standard 3-year warranty.
