Description
Overview
The Keysight R382A is a waveguide variable attenuator engineered for precision microwave applications. Unlike conventional adjustable flap attenuators, the R382A features attenuation control based on resistive card rotation angle rather than resistivity, making it insensitive to temperature and humidity variations and delivering highly accurate, stable attenuation.
