The Agilent/Keysight 435B is an analog power meter for RF and microwave power measurements. It interfaces with the complete 8480 series of power sensors to deliver measurement capability across extended frequency and dynamic ranges. The instrument incorporates an internal calibration source, auto-zero front-panel control, and a recorder output for data logging. Its ±1.2% worst-case accuracy and low noise/drift characteristics make it suitable for production testing, field calibration, and laboratory characterization of RF/microwave assemblies and components.
