Making a Power Measurement with USB Power Sensor
Making a Peak Power Measurement
The Keysight U2020 X-series USB peak and average power sensors
enable peak power measurements that have the same accuracy as
measurements obtained using traditional peak power meters, while
providing the advantages of being a very compact and portable
form factor.
Follow the steps below to make a peak power measurement.
1 Press
Mode > Power Meter
to access the power meter mode.
2 Connect the power sensor to the USB port of N932xC. The sensor
will automatically initialize, perform zeroing (While remaining
connect to the device under test), and calibrate without connecting
to an external source.
3 Press
General Setup > Freq
to set the frequency of the signal under
test.
As a wideband device, the power sensor has a frequency response.
The power sensor utilizes a complex correction algorithm to
remove power measurement error due to linearity error, frequency
response, and temperature drift to generate a more accurate
measurement.
NOTE
You can manually perform zeroing and calibration by perssing Zeroing >
Zeroing and Calibration at any time after the sensor is connected and
initialized.
