Agilent / Keysight 8592B 9kHz-22GHz MW Spectrum Analyzer

The Agilent/Keysight 8592B is a portable microwave spectrum analyzer delivering signal analysis across 9 kHz to 22 GHz, with optional coverage extending to 25 GHz or 26.5 GHz. Built for field deployment and lab work, it combines wide frequency reach with exceptional sensitivity - achieving -141 dBm DANL at 1 GHz and -137 dBm at 10 GHz - and >110 dB dynamic range. The instrument handles continuous input power to +30 dBm (1 W, 50 ohm) or +75 dBm V (0.4 W, 75 ohm with Option 001), making it suitable for component characterization and system troubleshooting in telecommunications, aerospace, and defense environments.
