The Anritsu MG3696A is a synthesized signal generator delivering precision frequency synthesis across 2 GHz to 65 GHz for advanced RF and microwave testing. Purpose-built for radar systems, telecommunications, aerospace, and defense applications, it combines low phase noise, stable frequency output, and high spectral purity in a configurable platform. Frequency resolution to 0.01 Hz and switching times under 40 ms enable rapid, accurate measurements in complex test environments. The instrument accepts internal or external 10 MHz reference inputs and offers extensive modulation and attenuation options to adapt to evolving measurement requirements.
