[ Summary ][ Features ][ Specifications ][ Key Literature ][ Ordering ][ Assistance ][ Related ]
The HP 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 HP E8462A can be programmed into individual topologies; some common examples are shown in the table below. Many other combinations of these topologies are supported (in addition to those shown in the table). Two-wire, three-wire, and four-wire measurements can be configured.
