Keysight (Agilent) U8481A USB Thermocouple Power Sensor
The Keysight U8481A USB thermocouple power sensors come with a measurement speed of 900 readings/second and power linearity of less than 0.8%, providing high accuracy and stability to help you make average power measurements quickly and confidently. Synchronize your measurement capture with the built-in trigger in function, without the need of an external module. The trigger-in function allows you to connect an external trigger signal from a signal source or the device-under-test directly to the USB sensor through a standard BNC to SMB cable. Save time and reduce measurement uncertainty with the internal calibration function.
The U8481A power sensor plugs directly into your PC or USB-enabled Keysight instrument and gives you the capability to measure power without needing an external power meter or power supply. The sensors draw power directly from a USB port and do not need additional triggering modules to operate. The Keysight U8481A, like all other Keysight USB power sensors, can be used as an accessory for other Keysight instruments, allowing these instruments to perform specific power measurement applications without needing to connect to a PC or laptop.
