FET Multiplexer Module Description
Chapter 1
This chapter describes the HP E1351A 16-Channel FET and the
HP E1353A 16-Channel Thermocouple FET Multiplexer Modules, and
shows how to program the modules using SCPI (Standard Commands for
Programmable Instruments) commands. This chapter contains the

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.
