The Keysight E1460A is a C-size, 1-slot VXI relay multiplexer delivering high-density signal routing for automated test systems. Built around latching armature switches, this register-based module configures into multiple topologies: 64 two-wire, 32 three-wire, 32 four-wire, or 128 single-ended channels. Configuration occurs via SCPI commands or jumper settings on the terminal card, enabling flexible deployment across wire harness testing, cable validation, semiconductor characterization, and PCB diagnostics.
