Description
Core Product Summary
The Keysight / Agilent E1460A is a high-density, 64-channel relay multiplexer module built on the VXIbus standard. Occupying a single C-size VXI slot, this register-based module utilizes latching armature switches to provide configurable, high-point-count signal switching within automated test system environments.
The board features versatile wiring topologies, allowing re-configuration into 64 2-wire, 32 3-wire, 32 4-wire, or 128 single-ended latching relay channels. Engineered for test system integration, the module interfaces with standard terminal blocks and utilizes SCPI-compatible command protocols when controlled via a VXI command module or slot-0 controller.

Detailed Product Overview
The Keysight / Agilent E1460A is a high-density C-size VXI multiplexer module designed for signal routing in complex automated test systems. Built on a register-based VXI architecture, the unit maximizes physical slot efficiency by providing up to 64 differential switching channels within a single-slot footprint.
The core switching subsystem utilizes latching armature relays. Because latching relays remain locked in their last commanded state without continuous current flow, they generate low internal heating during extended testing routines, preserving measurement precision across low-level analog channels. The internal relay layout supports multiple field-configurable topologies, allowing system designers to set up the board for 2-wire, 3-wire, 4-wire, or single-ended signal paths based on test requirements.
System deployment is supported by front-access screw terminal block assemblies or QUIC quick-interconnect housings. Programmers interact with the module via SCPI commands routed through a VXI slot-0 controller or command module, enabling automated open/close operations and channel scan sequences.
Engineering Selection Highlights
- VXI Standard Compliance: Operates as a single C-size slot register-based VXI module, integrating into standard VXI mainframes.

Applications & System Role
The Keysight Agilent E1460A serves as a central switching matrix/multiplexer element within VXI-based automated test equipment (ATE) architectures. Located between signal measurement instruments (such as digital multimeters, oscilloscopes, or signal sources) and the device under test (DUT), it automates routing across high-density connection points.
Due to its high channel density and flexible relay configurations, it is suited for automated testing environments such as cable/wire harness testing, printed circuit board (PCB) assembly functional testing, insulation resistance testing, and multi-point signal routing skids.
