Keysight 8494B Coaxial Step Attenuator
The Keysight 8494B Coaxial Fixed Attenuator is known for its high accuracy, low SWR, broadband frequency coverage, and compact size. Keysight 8494B attenuators are all tested on a state-of-the-art precision analyzer to assure specifications over the full frequency ranges. They employ a film on an attenuator card as the resistive element. The uniformity and repeatability of the film deposition process results in high accuracy and low SWR over very wide frequency ranges.
The Keysight 8494B Coaxial Step Attenuator was previously manufactured as the Agilent 8494B Coaxial Step Attenuator which replaced the HP 8494B Coaxial Step Attenuator.
