The Keysight M9164B is a 2×16 PXIe solid-state switch matrix for routing RF and microwave signals in automated test equipment. Operating from 300 kHz to 9 GHz, it delivers a full cross-bar configuration with 256 channels across a 2-wire topology, enabling cost-effective multiport switching for complex measurement scenarios. Built on the PXIe platform in a 2-slot form factor, the M9164B integrates directly with Keysight’s M980xA VNA series to support scalable multi-DUT and multiport measurements—ideal for applications such as 5G massive MIMO antenna characterization.
