The Keysight 70100A (formerly HP 70100A) is a single-slot Modular Measurement System (MMS) power meter module. Offering performance and capabilities equivalent to the classic HP 437B power meter, the 70100A is designed for high-density automated test environments. It features automatic calibration and zeroing, selectable resolution, and broad compatibility with the 8480 series of power sensors, covering a frequency range of up to 110 GHz.
