The Keysight Technologies 89605B RF Input Calibration VXI Plug-In Module is an RF input calibration accessory for VXI-based test systems, tracing its lineage to the Agilent/HP 89605B. Designed to slot into a VXI backplane, it supports RF input calibration routines to help ensure accuracy in RF measurements in laboratory and production environments. The 89605B carries the legacy Agilent HP designation while bearing Keysight branding, enabling continued calibration compatibility within a VXI subsystem.
