Agilent Technologies'thermocouple power sensors are fast,accurate

摘要

The U8480 series of USB thermocouple-based power sensors delivers a measurement speed of 400 readings/sec, with the ability to measure down to dc. USB functionality enables thesensor to plug directly into a PC or USB-enabled instrument to allow power measurements without an external power meter or power supply. The U8480 series provides power linearity of less than 0.8%, a built-in trigger function to synchronize measurement capture, and an internal calibration function that reduces measurement uncertainty. The U8481A model covers frequency ranges of 10 MHz to 18 GHz, and the U8485A covers 10 MHz to 33 GHz, with the option to expand the frequency range from 10 MHz down to dc.
