Agilent Technologies Inc. (Santa Clara, CA) has announced the addition of two new models to its U8480 Series USB thermocouple power sensors. The U8480 Series now includes an expanded frequency range to 67 GHz and a measurement speed of 900 readings/second. The U8480 Series’ real-time measurement uncertainty feature, the first of its kind in the industry, significantly reduces overall test time by removing the need for time-consuming manual measurement uncertainty (MU) calculations. Users can now compute MU in real time and at any given point. The feature also allows them to display power measurements and their MU simultaneously.
