Agilent/Keysight M9808A

The Keysight M9808A is a modular PXIe Vector Network Analyzer delivering RF and microwave characterization from 100 kHz to 53 GHz. This 2-port module cascades within a PXIe chassis to enable multiport configurations up to 50 ports, supporting synchronized N-port measurements with multiport error correction in a single chassis. The M9808A applies the same measurement science as Keysight's benchtop PNA and ENA series, ensuring repeatable S-parameter acquisition across broad frequency spans.
