Description
Overview
The Keysight 355C is a precision manual step attenuator that provides accurate step attenuation in 10 dB steps from 0 to 120 dB across a DC to 1 GHz frequency range. Cam-actuated microswitches keep lead lengths short, minimizing stray capacitances and inductances to maintain low phase shift. The compact, rugged design features rigid component positioning and shielding to prevent stray pickup and signal leakage. The 355C can be connected in series with the 355D to provide 1 dB resolution over a 0 to 132 dB range.
