The Agilent/Keysight 8566B is a high-performance spectrum analyzer spanning 100 Hz to 22 GHz, engineered for bench and ATE system integration. It delivers superior measurement speed, microwave frequency accuracy, and sensitivity for low-level signal analysis across its full range. The instrument’s synthesizer stability minimizes long-term drift and residual FM, while external mixers extend coverage to 325 GHz.
