VXI FET Multiplexers

[ Summary ][ Features ][ Specifications ][ Key Literature ][ Ordering ][ Assistance ][ Related ]
A multiplexer connects one point to one of many other points. The primary use of a multiplexer is to switch multiple analog signals to a voltmeter or other measuring instrument. Break-before-make operation ensures that no two signals are ever connected to each other during scanning operations. It is not possible to close multiple channels simultaneously on FET multiplexer modules.

Different multiplexers can switch one wire (high with a common low), or three wires (high, low, and guard or common). The choice of switching topology can be a trade-off between higher point count with single-ended switching or superior measurement accuracy (for example, three-wire guarded measurements). In addition to the FET Multiplexers shown here, HP also offers a full line of Relay Multiplexer Modules.
