Improve your power measurement
throughput with the world’s fastest
USB thermocouple power sensors. The
Keysight Technologies, Inc. U8480
Series 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. With the U8480 Series USB
sensors, one of the most cost-effective
solutions in Keysight’s power meter and
sensor portfolio, you get top performance
features at costs so affordable that every
engineer can carry one in their bags.
Broad frequency coverage from
DC to 120 GHz
Keysight’s first power sensor with the
capability to measure down to DC cover
various test applications and can be used
for broadband applications up to 120 GHz
without the change of power sensors.
U8481A DC/10 MHz to 18 GHz
U8485A DC/10 MHz to 33 GHz
U8487A 10 MHz to 50 GHz
U8488A 10 MHz to 67 GHz
U8489A DC to 120 GHz
Improve your power measurement throughput
Built-in trigger in function
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.
The U8480 Series 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 U8480 Series is supported by
the Keysight BenchVue software and
BV0007B power meter/sensor control
and analysis app. Once you plug the
USB power sensor into a PC and run
the software you can see measurement
results in a wide array of display formats
and log data without any programming.

The U8480 Series fits easily in your bag, making the
sensors ideal solutions for field applications such as
base station testing.

Internal calibration
Save time and reduce measurement
uncertainty with the internal calibration
function. These sensors come with
technology that integrates a DC reference
source and switching circuits into the body
of the sensor so you can calibrate the
sensor while it is connected to a device-
under-test. This feature removes the need
for connection and disconnection from an
external calibration source, speeding up
testing and reducing connector wear and
tear. To perform zeroing, simply turn off
the device-under-test.
Legacy excellence in a compact
and portable form factor
The U8480 Series is based on the same
front end design as the Keysight 8480
and N8480 Series power sensors,
now equipped with USB capabilities
and improved specifications such as a
measurement speed ten times faster than
the legacy series.
