The Keysight/Agilent/HP 436A is a general-purpose digital power meter designed for manual and automatic RF and microwave power measurements across the 8480 series of power sensors. It measures absolute and relative power with ±0.5% accuracy, displaying results in watts, dBm, or dB without manual conversion. The instrument combines intuitive front-panel operation with optional HP-IB programmability for automated test systems.
