The Agilent/Keysight 8595E is a portable RF spectrum analyzer spanning 9 kHz to 6.5 GHz, engineered for signal monitoring, component testing, and EMC measurements. Part of the 8590 E-Series, this instrument combines field portability with laboratory-grade performance through a modular internal cardcage architecture that accepts optional circuit cards to expand measurement capabilities.
