The Aeroflex SGA analog RF signal generators are compact and lightweight with low phase noise, high accuracy, and fast settling time. Applications include general-purpose, aerospace, and military test applications in laboratory, factory, and field environments. The intuitive LCD touch-screen interface allows modulated or swept RF signals to be set up using fewer keystrokes than required by traditional soft key models. A modular format, featuring the Aerolock locking mechanism, enables additional RF instruments such as a second signal generator and combiner to be mechanically coupled externally by the user. Models include the SGA 3, which has an operating frequency range of 100 kHz to 3 GHz, and the SGA 6, covering 100 kHz to 6 GHz.
