The U8487A from Keysight is a USB Thermocouple Power Sensor that can measure power for modulated and CW RF signals from 10 MHZ to 50 GHz. It has a 55 dB dynamic range and carries out more than 900 readings per second. The sensor has a real-time measurement uncertainty (MU) feature and achieves greater accuracy with the S-parameter and gamma correction features, which correct impedance mismatch errors as well as the errors caused by components inserted between the DUT and power sensor. Each sensor has a power linearity of less than 0.8% and comes with BenchVue software. These power sensors are ideal for applications ranging from PNA/MXG calibration to high-volume manufacturing.
