Description
Temperature Measurements
High-integrity voltage meas-
urements are possible with
three-wire high, low, and guard
switching. In addition to making
two-wire resistance and precision
four-wire resistance measure-
ments, you can make up to
64 channels of thermocouple
temperature measurements
with automatic cold junction
compensation.
The Agilent E1476A High-Density
Reed Relay Multiplexer is a
C-size, 1-slot, register-based
VXI module. This low-offset,
thermocouple compensated
multiplexer is dynamically
configurable providing 64 chan-
nels of two-, three- or four-wire
(32 channels) of switching. This
multiplexer module consists of
a component card with switches
and a QUIC spring clamp termi-
nal block that plugs onto the
component card. The E1476A is
ideal for applications needing a
relay multiplexer that is dynami-
cally configurable, and makes
maximum high-quality, high-point
count measurements.
The reference thermistor is also
accessible by both banks, each
bank having a control switch
allowing for either a two-wire or
four-wire resistance measure-
ment of the 5000 Ω reference
thermistor mounted on the
isothermal plane located in the
terminal block. Using a scanning
multimeter configuration, the
channel relays and five control
relays are programmed by SCPI
commands or by register read/
writes. SCPI command syntax
to make a temperature scan
of K type thermocouples is:
MEAS:TEMP? TC, K, (@100:163)

Configuration
Product Specifications
Each of the 64 channels provides
separate high, low, and guard
connections, all easily accessible
via the quick connect screwless
terminals on the companion
terminal block. The multiplexer
is organized in two banks of
32 with each bank having its own
voltage sense control switch and
one bank having a current source
control switch. This dual bank
configuration makes it possible
to use half the channels as sense
channels, while the other half are
used as current source channels,
thus obtaining 32 four-wire mea-
surement channels, each with
high, low, and guard connections.

One 6 cm (2.5-in) analog bus
cable (E1400-61605) is shipped
with each module to allow you to
interconnect the E1411B 5.5-digit
multimeter to one or more E1476A
multiplexers via its front panel
analog bus connector. For con-
nection to an external voltmeter
or other VXI multimeter with
conventional front panel con-
nectors, access to the analog bus
lines is available in the terminal
block. This allows you to connect
the analog bus signal lines to the
multimeter inputs using ordinary
hookup wire.
