The Agilent/Keysight 8560A is a portable RF spectrum analyzer built for signal analysis across EMI diagnostics, component testing, and signal monitoring applications. Its synthesized local oscillator delivers drift-free, stable measurements from 50 Hz to 2.9 GHz (DC-coupled) or 100 kHz to 2.9 GHz (AC-coupled). The instrument combines high sensitivity with flexible bandwidth control to meet demanding field and laboratory requirements.
