Introduction
The Keysight Technologies, Inc. N8480 Series thermocouple power sensors are amongst
the most accurate and reliable sensors, plus they include EEPROM, and extended
frequency and power ranges.
Accurate, repeatable measurements
Here’s how: Excellent linearity (1% approximately) and noise specifications. The sensors’
low SWR further enhances accuracy by minimizing mismatch uncertainty. These sensors
also come with dual-range power for greater sensitivity to fluctuating signals. With high
accuracy and stability, the N8480 helps you test confidently, faster.
Calibration-easy testing
During test, calibrating your sensor is an essential step. Minimizing the time this step
takes is essential. The N8480 sensor eliminates cumbersome keying-in of the calibration
factor (CF), eliminates manual input errors, and saves you time and effort. CF, linearity,
and temperature corrections are all stored in the sensors’ EEPROM—auto-downloaded
on calibration. The N8480 Series streamlines the calibration procedure making overall
testing faster and more efficient.
One sensor, WIDEST range
Pick an N8480 sensor—any one—and you’ll see how its wide dynamic range equips you
for various
applications: metrology labs, radar, mobile radio, TDMA, GSM, W-CDMA, and WiMAX™,
among others.
With up to 55 dBm wide dynamic range, the N8480 Series offers you the widest
thermocouple sensor power range in the industry.
System integration can be difficult, but not with the N8480
The N8480 Series sensors are backward compatible with the Keysight leading range of
power meters, including the P-Series, EPM-P Series, and EPM Series. All that’s needed is
a simple firmware upgrade that’s downloadable for free from the Website.
All SCPI codes used on the E-Series sensors are re-usable on the N8480, including
most of the codes used on the 8480 Series. When migrating code from the 8480 Series,

will allow SCPI codes to behave much like they do on the 8480 Series.
Features
