The Keysight E8462A High-Density Relay Multiplexer is a C-size, 1-slot, register-based VXI module. This 256-channel multiplexer, using non-latching armature relays, offers a fast, reconfigurable, high point-count switching topology. This single-slot multiplexer extends the choices of multiplexers available to the system engineer. The E8462A can be programmed into individual topologies, including two-wire, three-wire, and four-wire measurement configurations.
