Agilent/Keysight 85530B

The Keysight 85530B is an ambient temperature CalPod Module designed for Keysight PNA family network analyzers and PXIe vector network analyzers. It enables rapid calibration refresh without removing the Device Under Test or reconnecting standards, simplifying multi-port and multi-path measurement scenarios. By characterizing CalPods with an ECal module, the 85530B allows CalPods to function as ECal modules within the measurement environment, supporting one-port calibration on each port of multi-port devices and facilitating full two-port 12-term error correction models.

Compatibility & Integration The 85530B integrates with PNA-X N524xA, PNA N522xA, and PNA-L N5231/32/34/35/39A series analyzers, as well as M937xA PXIe vector network analyzers. Legacy support includes Keysight 8510C, 8510B, 8510XF, 8510XG, 8510XE, 8510XS, 8510XT, and 8515A models. Operation requires CalPod firmware, an 85523B CalPod Controller, and the 85556A fan-out cable splitter for controlling more than four CalPods.
