Agilent/Keysight Y1151A

The Agilent/Keysight Y1151A is a distribution board that routes power and control signals from a driver module to external matrix switches within test and measurement systems. It plugs directly onto the 34945EXT and interfaces with up to two matrix switches using standard cabling, enabling straightforward signal and power distribution in modular switching architectures.

Technical Specifications

Typical Applications

• External matrix switch interfacing in automated test systems


• Power and control signal distribution to 87104x/106x L7x0xx multiport switches


• Integration with 87406B matrix switch configurations


• Multi-switch routing in modular Keysight 34945A platform systems

Compatibility & Integration The Y1151A integrates with the Keysight 34945A measurement platform through the 34945EXT module (sold separately). The board can work with two specific matrix switch families: the 87104x/106x L7x0xx multiport switches and the 87406B matrix switches. As part of a modular series, the Y1151A can be combined with other distribution boards in the Y1150A–Y1155A range to build custom switching configurations. Standard cabling connects the board to external switches; compatible cable kits are available separately for specific pin configurations.
