Agilent Technologies Inc. announced the Agilent U8480 Series, the world’s fastest USB thermocouple power sensors. Based on the same front-end design as the Agilent 8480 and N8480 Series power sensors, the new U8480 Series offers improved specifications, including a measurement speed of 400 readings per second, 10 times faster than the legacy series.

The U8480 Series provides the best accuracy in Agilent’s power-meter and sensor portfolio and comes with a power linearity of less than 0.8 percent. As Agilent’s first power sensor with the ability to measure down to DC, the U8480 Series covers a broader range of test applications. DC-range measurements are frequently used for source calibration, as power-measurement references, and for testing select electromagnetic compatibility.

With USB functionality, U8480 Series power sensors plug directly in to PCs or USB-enabled Agilent instruments and offer users the ability to measure power without needing an external power meter or power supply. With their built-in trigger function, Agilent’s thermocouple power sensors give test engineers the ability to synchronize measurement capture without needing an external module. The internal calibration function saves time and reduces wear and tear on connectors. These power sensors also come bundled with Agilent’s N1918A Power Panel software, making the U8480 Series one of the most cost-effective solutions in the company’s power-meter and sensor portfolio.

“Thermocouple -based power sensors are known for providing accurate power measurements but with a trade-off of slower measurement speeds,” said Ee Huei Sin, vice president, Agilent’s Basic Instruments Division. “The U8480 Series overcomes this limitation and offers a significant improvement in measurement speed, making these sensors ideal for users who require high throughput and accuracy.”
