Datasheet

Agilent Technologies has added two new models to its U8480 Series USB thermocouple power sensors. The new models have improved specifications, including an expanded frequency range to 67GHz and a measurement speed of 900 readings/second. The U8480 Series’ real-time measurement uncertainty feature 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, simplifying test measurement and increasing test accuracy.

The sensors provide best accuracy and repeatability with thermocouple sensing technology and a power linearity of less than 0.8 percent. The new S-parameter and gamma correction functions further improve measurement accuracy by correcting the mismatch errors caused by inserted components between the device-under-test and the power sensor, making the sensors suitable for applications such as test system or instrument calibration.

The sensors can be used as an accessory for other Agilent instruments, allowing these instruments to perform specific power measurement applications without needing to connect to a PC or laptop. The U8480 Series is compatible with Agilent FieldFox RF analysers and MXG signal generators, giving them power meter functionalities. The power sensors also perform source power calibration with Agilent PNA, PNA-L and PNA-X network analysers. USB functionality and the bundled N1918A Power Panel software enables measurement of high-frequency power measurements in applications ranging from high-volume manufacturing to calibration and field remote monitoring.
