FET Multiplexer Module Description

The FET multiplexer module provides high-speed switching (multiplexing) for up to 16 channels. The module can be used as a scanning multiplexer for a scanning voltmeter configuration, or as a stand-alone multiplexer in a switchbox configuration. The channels are numbered 00 to 15. Each channel provides connections for High (H), Low (L) and Guard (G), although only High and Low are switched. The FET multiplexer module can switch up to 100,000 connections per second (100 K switches/sec).

The FET multiplexer module consists of a component assembly and a terminal module. There are three different terminal modules, one for each of the following applications: HP E1351A 16-Channel FET Multiplexer Module, HP E1353A 16-Channel Thermocouple FET Multiplexer Module, and HP E1352A 32-Channel Single-Ended FET Multiplexer Module. The component assembly is the same for all three applications. For information on the 32-Channel Single-Ended FET Multiplexer Module, see the

HP E1352A User’s Manual.

The component assembly contains the VXIbus interface, the FET switches, the analog bus connector and the digital bus. The terminal modules provide connection points for the individual channels, as well as monitoring points for the tree terminals and the direct terminals. The FET multiplexer module can be externally triggered from the VXIbus backplane or through the digital bus handshake lines on the front of the component assembly.
