Agilent Technologies’ New Thermocouple Power Sensors Offer Widest Dynamic Range for Average Power Measurements


Agilent Technologies Inc. (NYSE: A) today introduced new thermocouple power sensors that offer industry-leading dynamic range in average-power measurements. As an enhanced replacement for the Agilent 8480 Series, the new sensors cover a power range of -35 dBm to +20 dBm and span a frequency range of 100 kHz to 33 GHz (model dependent).

By extending the power range down to -35 dBm, the Agilent N8480 Series of thermocouple power sensors provides an industry-leading 55 dB dynamic range in a single sensor. Measurement speed and repeatability at low power levels have also been improved. Each member of the N8480 Series has been optimized for a specific frequency range, and all offer high measurement accuracy with excellent power linearity.

The Agilent N8480 Series incorporates a built-in EEPROM for storing calibration factors. This feature enables automatic loading of cal factors, reducing manual input errors and increasing productivity. An optional calibration-factor table (Option CFT) enables manual entry of cal factors, matching the performance and operation of Agilent’s 8480 family of sensors. Option CFT also provides SCPI-code compatibility with the 8480 Series.

“The N8480 Series is the new performance leader for challenging applications in communications, electronics manufacturing, aerospace and automotive electronics,” said Ee Huei Sin, vice president and general manager of Agilent’s Basic Instruments Division. “Features such as backwards compatibility with Agilent EPM, EPM-P and P-Series power meters make it easy to migrate to these excellent new sensors.”

Agilent is offering a 30-percent discount off any N8480 Series sensor with the trade-in of select 848X sensors. Details are available at

Further Information

The three new sensors cover the following frequency ranges:

* N8481A: 10 MHz to 18 GHz;
* N8482A: 100 kHz to 6 GHz; and
* N8485A: 10 MHz to 26.5 GHz or 10 MHz to 33 GHz with Option 033.
