Agilent / Keysight 8566B Spectrum Analyzer, 100 Hz to 22 GHz

The Agilent/Keysight 8566B Spectrum Analyzer is a high-performance instrument designed for bench and ATE system use, offering a wide frequency range from 100 Hz to 22 GHz. It is engineered for superior measurement speed, microwave frequency accuracy, and sensitivity, enabling the analysis of low-level signals up to 22 GHz with narrow resolution bandwidths. The analyzer’s synthesizer stability effectively minimizes long-term drift and residual FM. Its capabilities can be extended to 325 GHz with external mixers, making it suitable for a broad spectrum of applications including telecommunications, aerospace, electronics manufacturing, EMC testing, and broadband signal surveillance. The instrument features an internal bus and microcomputer control, providing significant operating and data processing features, along with flexibility for computer control. It includes 16 KB of user RAM for storing trace data, instrument states, and custom downloadable programs (DLPs), and all displayed information can be sent to a plotter when the sweep time is 20 ms or greater.
