Agilent / Keysight U8481A USB Thermocouple Power Sensor DC-18Ghz


The U8480 series is Keysight’s first power sensor with the capability to measure down to DC (with option 200). This is especially useful for Signal Source/Network Analyzer calibration and power references as well as EMC applications.


  • Frequency range of DC/10MHz to 18 GHz
  • Fastest measurement speed for thermocouple sensor, > 400 readings/s (free run/fast buffer mode)
  • Best-in-class power linearity of less than 0.8%
  • Wide dynamic range from -35 dBm to +20 dBm
  • Accurate calibration and traceability to US National Institute of Standards and Technology (NIST) or National Physical Laboratory (NPL)
