4 Safety and Support Information
Ground the System
To minimize shock hazard, the
system chassis must have a
hard-wired connection to an
electrical protective earth
ground. The system must also be
connected to the ac power mains
through a power cable that
includes a protective earth
conductor. The power cable
ground wire must be connected
to an electrical ground (safety
ground) at the power outlet. Any
interruption of the protective
grounding will cause a potential
shock hazard that could result in
personal injury.
Fuses
Use only fuses with the required
rated current, voltage, and
specified type (normal blow,
time delay). Do not use repaired
fuses or short-circuited fuse
holders. To do so could cause a
shock or fire hazard.
Operator Safety Information
MODULE CONNECTORS AND
TEST SIGNAL CABLES
CONNECTED TO THEM
CANNOT BE OPERATOR
ACCESSIBLE: Cables and
connectors are considered
inaccessible if a tool (e.g.,
screwdriver, wrench, socket,
etc.) or a key (equipment in a
locked cabinet) is required to
gain access to them.
Additionally, the operator
cannot have access to a
conductive surface connected to
any cable conductor (High, Low
or Guard).
ASSURE THE EQUIPMENT
UNDER TEST HAS
ADEQUATE INSULATION
BETWEEN THE CABLE
CONNECTIONS AND ANY
OPERATOR-ACCESSIBLE
PARTS (DOORS, COVERS,
PANELS, SHIELDS, CASES,
CABINETS, ETC.): Verify there
are multiple and sufficient
protective means (rated for the
voltages you are applying) to
assure the operator will NOT
come into contact with any
energized conductor even if one
of the protective means fails to
work as intended. For example,
the inner side of a case, cabinet,
door, cover or panel can be
covered with an insulating
material as well as routing the
test cables to the module’s front
panel connectors through
non-conductive, flexible conduit
such as that used in electrical
power distribution.

Introduction
The Agilent E6171B Measurement Control Module is an instrument
multiplexer and voltage/current source module designed for automotive
electronic test applications. Key features of the module include:
•An isolated voltage source.
•An isolated current source with a programmable voltage limit.
•A 16 X 5 instrument multiplexer that multiplexes four analog buses
plus Device Under Test (DUT) common.
•Multiplexing for eightexternal triggers and eightVXIbus TTL triggers
to and from each other or to and from the DUT.
•An analog comparator, with programmable thresholds, whose output
connects to the trigger multiplexer.
•A programmable high-voltage attenuator.
•A amplifier with programmable gain that can amplify the output of an
Agilent E6173A Arbitrary Function Generator module (formerly the
Agilent Z2471A) via a step-up transformer to provide output for
simulating VRS (Variable Reluctance Sensors) signals.
•A Programmable IRQ.
•A programmable general-purpose timer whose output also can be used
to generate interrupts, trigger delays, and pacing.
Note The Agilent E6171A and E6171B are functionally equivalent. The module
was updated to the "B" version to improve overall manufacturability and
calibration.

Warnings and Cautions
WARNING SHOCK HAZARD. Only service-trained personnel who are
aware of the hazards involved should install, remove, or
configure the switch module. Before you remove any installed
module, disconnect AC power from the mainframe and from
other modules that may be connected to the modules.
Do not defeat the Agilent E6171B Measurement Control Module
Interlock feature with jumpers.
An interlocked safety cover is recommended to prevent
operator access to electric shock hazard voltages and currents
that may be applied to the unit under test.
Voltages greater than 30 Vrms, 42 Vpk, or 60 Vdc are
considered hazardous voltages. Current greater than 8 A or
energy greater than 150 VA is also considered hazardous.
AVERTISSMENT NE pas neutraliser le verrouillage de l'appareil de mesure
E6171B.
Un couvercle des sécurité à verrouillage est recommandé afin
de protéger l'opérateur des chocs électriques causés par des
tensions ou des courants qui peuvent ètre appliqués à
l'appareil à l'essai. Les tensions superieures a 30 V (eff.), 42 V
(crete) ou 60 V (c.c.) sont dangereuses. Un courant supérieures
à 8 A ou une énergie supérieure à 150 V-A sont dangereux.
Caution STATIC ELECTRICITY. Static electricity is a major cause of
component failure. To prevent damage to the electrical
components in the switch module, observe anti-static
techniques whenever removing a module from the mainframe
or whenever working on a module.

Introduction
Figure 2-1 shows a simplified block diagram of the Agilent E6171B in a
typical Agilent TS-5400 Family application. THe application includes one
Agilent E6172A 32-Channel Pin Matrix module and four other test
instruments.
Description of Features
The Measurement Control Module contains:
•A 16 X 5 matrix of dry reed relays used to multiplex instruments.
•An isolated—i.e., “floating”—dual-range voltage and current source
that also can be used as an amplifier for the Agilent E6173A Arbitrary
Waveform Generator Module (formerly Agilent Z2471A), and
optionally, high-voltage transformer output.
•A trigger multiplexer that provides access for external equipment
triggers to the VXIbus TTL triggers and Device Under Test (DUT).
•An analog comparator whose output is routed to the trigger
multiplexer.
•A general-purpose timer that can run in one-shot or free running
modes. Besides being used for general timing applications, its output
can be routed to any of seven interrupt lines and used for triggering,
generating delays, or pacing.
•A DUT-referenced measurement system (a path through relays that
connects DUT ground to system or chassis ground).

16 X 5 Instrument
Multiplexer As many as sixteen external inputs to the MeasurementControl Module can
be connected to any of the four analog columns or to the common DUT
ground that exit this card via the ABus1-ABus4. You can use these inputs as
follows:
•Because the Agilent E1411 DMM is used to measure the output of the
V/I source, the DMM must always be connected to external inputs 1-4
as DVM Hi, DVM Lo, Isource Hi, and Isource Lo, respectively.
•The Measurement Control Module provides special routing for signals
from the Agilent E6173A Arbitrary Function Generator Module,
which must always be connected to external inputs 5 & 6, Hi and Lo,
respectively.
•If a digitizer, such as the Agilent E1429A, is used in the system, it
should be wired to row 7 through 10.
•Finally, row 11 and 12 are set aside for a counter, such as the Agilent
E1333A counter.
•The external inputs 13 through 16 are undefined and can be used with
any additional instruments.
•Row 17-19 is not available, and rows 20 through 32 have assigned
uses already.
The Agilent E6171B can route any of the 16 external instruments as well as
any of its internal resources (V/I source, analog comparator, digital trigger,
and attenuator) to the five measurement buses and then to one or more
Agilent E6172A 32-Pin Matrix Modules.
Trigger Multiplexer The trigger multiplexer lets you interconnect various combinations of
external triggers, VXIbus trigger lines, and the output from the analog
comparator on the Measurement Control Module. This helps with complex
DUT trigger scenarios with VXI instruments. You can simultaneously
connect two independent trigger paths.
Figure 2-2 is a simplified block diagram of the trigger MUX-DEMUX
arrangement. The sources and destinations of the triggers are shown in
greater detail in Figure 2-3.

18 Understanding the Agilent E6171B Chapter 2
By default, external trigger outputs and the digital trigger output are pulled
up to 5 volts. However, the digital trigger output can be pulled up to 30 volts
via external source and pull-up resistors for DUT triggering. The digital
trigger output from the trigger multiplexer can be connected to any of the
columns on ABus1-ABus4. The digital trigger output and comparator input
“float” to the DUT common.
You can connect more than one trigger source and trigger destination per
trigger path to provide synchronization between devices. For example, a
trigger source on the DUT could connect to both a counter and the external
trigger port on a DVM and use only one path in the trigger multiplexer.
Figure 2-3 shows a conceptual diagram of the bus structure in the trigger
multiplexer. Arrows indicate whether the various lines connected to the
trigger buses are inputs, outputs, or bi-directional.

Understanding the Agilent E6171B Measurement Control Module 19Chapter 2
The trigger multiplexer contains two trigger buses, nominally known as
TRIG1 and TRIG2, used to route signals. Any of the eight, bi-directional
TTL-level triggers at the VXIbus backplane can connect to either of the
trigger multiplexer's buses and can be used as trigger sources or trigger
destinations. The connections are made electronically through an
“open-collector” bus. If any selected input is low, then the bus is low.
Otherwise, the bus is high. In a similar fashion, any of the eight external
trigger lines available on the module's front panel can connect to either of
the two multiplexer buses.
The routing and configuration of all sixteen of the lines described above is
controlled by writing control data to the various Trigger Configuration
Registers (see Appendix B).
There are three other trigger sources you can connect to the trigger buses.
The first, “timer output” in the diagram, is an output from the
general-purpose timer. Its routing to TRIG1 or TRIG2 is controlled by bits
1 and 4 of the Other Trigger Resources Register (see Appendix B). The
