The Agilent/Keysight 83711 is a synthesized CW signal generator engineered for precision frequency and power control across microwave and millimeter-wave applications. Available in two frequency variants—83711A/11B covering 1 GHz to 20 GHz and 83712A/12B spanning 10 MHz to 20 GHz—the instrument delivers maximum leveled output power of +11 dBm across 1–18 GHz (standard) with a dynamic range exceeding 100 dB. Minimum leveled output reaches −4 dBm (standard) or −110 dBm with Option 1E1, enabling demanding attenuation requirements.
