Key Features and Functions

Based on the same front end design as the Keysight 8480 and N8480 Series power sensors, the new U8480 Series offers improved specifications, including a measurement speed more than 20 times faster than the legacy series (900 readings/sec vs 40 readings/sec).

Now with USB capabilities, the U8480 Series plugs directly into your PC or USB-enabled Keysight instrument and gives you the capability to measure power without the need of an external power meter or power supply.
