Keysight / Agilent 8490D Series Coaxial Attenuators

  • Multiple Attenuation Values
  • 2.4mm Connector
  • Bench and System Applications


The Keysight / Agilent Technologies 8490D Series Coaxial Attenuators are a part of a line of precision fixed coaxial attenuators with performance specified up to 50 GHz. These attenuators use the 2.4 mm coaxial connector, which exhibits excellent performance from dc to 50 GHz. The 8490D family has attenuation values of 3, 6, 10, 20, 30, and 40 dB. The Keysight / Agilent 8490D family of 2.4 mm fixed coaxial attenuators is assembled and tested with the same meticulous care as their lower frequency counter parts: the Keysight / Agilent 8491, 8492, and 8493 families. These attenuators are all tested on Keysight / Agilent precision analyzers to assure specifications over the full frequency range.

Ruggedness, reliability, and small size make these attenuators useful both on the bench and in systems applications. With their accuracy and low SWR they are ideally suited for extending the range of sensitive power meters for higher power measurements. The same characteristics lend themselves to applications such as calibration standards and RF substitution measurements. With their broad dc to 50 GHz frequency range and reasonable cost, general applications such as the reduction of power level to sensitive components and instrumentation systems are attractive and appropriate uses for these attenuators.

Product Family: 8490D

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
