This unit
The Keysight U8488A is a USB-powered thermocouple power sensor for direct average power measurement across microwave and millimeter-wave frequencies. Built on the proven front-end architecture of the 8480 and N8480 series, it delivers measurement speeds up to 900 readings per second - 22× faster than legacy designs. The compact form factor draws power directly from USB, eliminating external supplies and enabling portable field deployments without a separate power meter.
