The Keysight (Agilent) 8493C is a precision fixed coaxial attenuator that provides flat frequency response and low SWR from DC to 26.5 GHz. It features 3.5 mm (APC-3.5) connectors and handles up to 2 W of average power and 100 W of peak power. The 8493C is available in nominal attenuation values of 3 dB, 6 dB, and in 10 dB increments from 10 dB to 40 dB, with swept-frequency calibration points provided on a nameplate chart on each unit.
