This unit
The Keysight E8462A is a C-size, 1-slot VXI multiplexer module built on non-latching armature relays for high-density signal routing in automated test and data acquisition systems. With 256 channels and eight programmable switching topologies, it accommodates two-wire, three-wire, and four-wire measurement configurations. Register-based control enables flexible, reconfigurable signal paths across diverse circuit topologies.

Key Features
Eight independent switching topologies support varied measurement configurations without hardware reconfiguration
Terminal block options (sold separately) provide voltage and protection flexibility across three connector variants
Included 2.5-in. analog bus cable (E1400-61605) enables direct slot-adjacent module integration
Register-based control simplifies programmable routing within VXIbus systems
Typical Applications Automated test systems requiring multi-channel signal distribution, resistance measurement networks, temperature sensor multiplexing, and multi-point data acquisition with configurable measurement topologies.
Compatibility & Integration Register-based VXI module designed for E1400-series VXIbus systems. Direct compatibility with E1411B multimeter modules via included analog bus cable. Terminal block integration requires separate procurement of appropriate Option 012, 014, or 015 terminal card.
