Agilent / Keysight 8569B MICROWAVE Signal Analyzer

The Agilent/Keysight 8569B Microwave Signal Analyzer delivers precise RF and microwave signal analysis from 0.01 GHz to 22 GHz using its internal mixer, with external mixer capability extending measurements to 115 GHz. Built for EMI testing, signal surveillance, and microwave component characterization, this analyzer combines wide dynamic range, high sensitivity, and microprocessor-controlled operation with digital display readout for repeatable, efficient measurements.
