Keysight Technologies 355D

The Keysight (Agilent) 355D is a manual step attenuator offering 10 dB steps from 0 to 120 dB, operating from DC to 1 GHz. Featuring cam-actuated microswitches for low stray capacitance and inductance, it ensures minimal phase shift. Compact and rugged, the 355D is well-shielded to eliminate signal leakage and pickup. It can be paired with the 355C to extend attenuation range to 132 dB in 1 dB steps.

Suitable for precise RF attenuation tasks, it offers maximum SWR of 1.2 to 1.5 across frequencies and repeatability of 0.03 dB over 0.5 million cycles. Includes BNC female connectors with optional alternatives.
