• 1x Agilent Keysight 8490D-003 Fixed Coaxial Attenuator

The Keysight 8490D family is 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 family is assembled and tested with the same meticulous care as the lower-frequency Keysight 8491, 8492, and 8493 attenuator families, and all units are tested on Keysight precision analysers to assure specifications are met over the full frequency range.

Each attenuator is swept-frequency tested to ensure specifications are met at all frequencies. Calibration points are provided on a nameplate chart attached to each unit.
