The Agilent/Keysight 8920A is a portable RF communication test set that consolidates over 20 instruments into a single unit for service and repair of cellular and land mobile communication systems. It performs single-key characterization of transmitters and receivers across frequencies up to 1 GHz, displaying results digitally or in analog format on a single screen. The 8920A integrates signal generation, RF analysis, modulation measurement, and audio signal generation and analysis—reducing setup complexity and accelerating field diagnostics for technicians servicing cellular phones, land mobile radios, and broader communication equipment.
