The Agilent/Keysight 8562A is a portable spectrum analyzer delivering synthesized tuning for drift-free accuracy across 1 kHz to 22 GHz, with optional extension to 26.5 GHz or 325 GHz via external mixers. Purpose-built for RF and microwave measurement in field environments, it combines military-specification ruggedization with comprehensive signal analysis capabilities. The instrument provides resolution bandwidth from 100 Hz to 2 MHz, video bandwidth to 3 MHz, and AM/FM demodulation. Its -120 dBm displayed average noise level (1 MHz to 2.9 GHz) and 118 dB dynamic range enable detection and characterization of weak signals across multiple frequency bands. Input protection handles +30 dBm average continuous power and +50 dBm peak pulse power, with rigid mechanical design withstanding 30 g shock and MIL-T-28800C transit specifications.
