Agilent/Keysight 85532B

The Agilent/Keysight 85532B is a CalPod (Calibration Pod) designed to enable in-situ calibration refreshes within thermal-vacuum chamber environments without removing the Device Under Test or reconnecting calibration standards. This calibration refresh module integrates with Keysight PNA and PXIe vector network analyzers to eliminate thermal effects from test cables and connectors, maintaining measurement accuracy across demanding aerospace and satellite testing applications.
