Agilent/Keysight Y1155A

The Keysight Y1155A is a distribution board that routes power and control signals from the 34945EXT microwave switch/attenuator driver module to external switches via standard cables. It enables control of up to 16 switch coils through screw terminal connections, simplifying integration of switches and attenuators into automated test systems.

Compatibility & Integration The Y1155A is part of the Y1150A–Y1155A distribution board series, each optimized for specific switch and attenuator types. It mounts directly onto the 34945EXT driver module without additional hardware. The 34945A mainframe integrates the 34945EXT for complete switch control within modular test platforms. Optional Y1159A 16-to-16 pin cable kits provide pre-configured interconnect solutions for rapid system deployment.
