Agilent/Keysight 435A

The Agilent/Keysight 435A is a benchtop analog power meter engineered for precise RF and microwave power measurements. It delivers ±1% accuracy across a -65 dBm to +44 dBm dynamic range and operates from 100 kHz to 50 GHz when paired with compatible 8480 series power sensors. The instrument features low noise and drift characteristics, auto-zero functionality, and an internal calibration source that maintains long-term measurement integrity.
