Keysight J7211B Attenuation Control Unit

Overview

The Keysight J7211B is a compact attenuation control unit providing an integrated solution for R&D and manufacturing engineers in wireless communication, aerospace, defense, and electronic component industries. Operating from DC to 18 GHz with 0 to 121 dB attenuation in 1 dB steps, the J7211B features exceptional insertion loss repeatability of less than 0.03 dB per section over 5 million cycles. The unit is designed in a compact half-rack, 2-unit-high form factor for efficient benchtop and ATE applications.
