Figure 1-1 shows a typical layout for each of the relay multiplexers. Each
multiplexer consists of a component assembly and a terminal module. The
Agilent E1345A, E1347A, E1355A, and E1356A multiplexers use the same
component assembly, but each multiplexer uses a unique terminal module.
The Agilent E1343 and E1344 multiplexers use a different component
assembly.

General Information 11
Safety Considerations
These products are Safety Class I instruments provided with a protective
earth terminal when installed in the mainframe. Check the mainframe,
multiplexer, and all related documentation for safety markings and
instructions before operation or service.
Refer to the WARNINGS on page 4 in this manual for a summary of safety
information. Safety information for preventive maintenance, testing, and
service follows and is also found throughout this manual.
WARNINGS
WARNING
This section contains WARNINGS which must be followed for your
protection when performing equipment maintenance or repair.
SERVICE-TRAINED PERSONNEL ONLY. The information in this
manual is for service-trained personnel who are familiar with
electronic circuitry and are aware of the hazards involved. To
avoid personal injury or damage to the instrument, do not
perform procedures in this manual or do any servicing unless
you are qualified to do so.
CHECK MAINFRAME POWER SETTINGS. Before applying
power, verify that the mainframe setting matches the line
voltage and that the correct fuse is installed. An uninterruptible
safety earth ground must be provided from the main power
source to the supplied power cord set.
GROUNDING REQUIREMENTS. Interruption of the protective
(grounding) conductor (inside or outside the mainframe) or
disconnecting the protective earth terminal will cause a
potential shock hazard that could result in personal injury.
(Grounding one conductor of a two-conductor outlet is not
sufficient protection.)
IMPAIRED PROTECTION. Whenever it is likely that instrument
protection has been impaired, the mainframe must be made
inoperative and be secured against any unintended operation.
REMOVE POWER IF POSSIBLE. Some procedures in this
manual may be performed with power supplied to the
mainframe while protective covers are removed. Energy
available at many points may, if contacted, result in personal
injury. (If maintenance can be performed without power applied,
the power should be removed.)
12 General Information
Chapter 1
WARNING
USING AUTOTRANSFORMERS. If the mainframe is to be
energized via an autotransformer (for voltage reduction) make
sure the common terminal is connected to neutral (that is, the
grounded side of the main’s supply).
CAPACITOR VOLTAGES. Capacitors inside the mainframe may
remain charged even when the mainframe has been
disconnected from its source of supply.
USE PROPER FUSES. For continued protection against fire
hazard, replace the line fuses only with fuses of the same
current rating and type (such as normal blow, time delay, etc.).
Do not use repaired fuses or short-circuited fuseholders.
WIRING INSULATION. To prevent electrical shock, all wires to
the channel connections must be insulated to at least 120 V rms
(170 V peak).
CAUTIONS
CAUTION
This section contains CAUTIONS which must be followed to avoid damage
to the equipment when performing instrument maintenance or repair.
MAXIMUM VOLTAGE/CURRENT. The maximum voltage that
may be applied between High (H), Low (L), and Guard (G)
terminals is 170VDC or 120Vrms (170Vpeak) for the E1345A,
E1347A, E1355A, and E1356A modules. The maximum voltage
that may be applied between High (H), Low (L), and Guard (G)
terminals is 250VDC or ACrms (354Vpeak) for the E1343A or
E1344A. The maximum current is 50 mA (non-conductive) per
channel. The maximum power per channel is 1 VA.
STATIC ELECTRICITY. Static electricity is a major cause of
component failure. To prevent damage to the electrical
components in the multiplexers, observe anti-static techniques
whenever working on a multiplexer.
Chapter 1
General Information 13
Relay Life
Electromagnetic relays are subject to normal wear-out. Relay life depends
on several factors. Two factors are loading and switching frequency effects.
Loading and
Switching
Frequency Effects
Relay Load. In general, higher power switching reduces relay life. In
addition, capacitive/inductive loads and high inrush currents (e.g., when
turning on a lamp or motor) reduce relay life. Exceeding the specified
maximum inputs can cause catastrophic failure.
Switching Frequency. Relay contacts heat up when switched. As the
switching frequency increases, the contacts have less time to dissipate heat.
The resulting increase in contact temperature reduces relay life.
End-of-Life
Detection
A preventive maintenance routine can prevent problems caused by
unexpected relay failure. The end-of-the life of a relay can be determined
using one or more of the following methods. The best method (or
combination of methods), as well as the failure criteria, depends on the
application in which the relay is used.
Check Contact Resistance. As a relay begins to wear out, its contact
resistance will increase. When the resistance exceeds a pre-determined
value, the relay should be replaced. Typically, a relay should be replaced
when the contact resistance exceeds 2.0Ω.
Check Stability of Contact Resistance. The stability of relay contact
resistance decreases with age. Using this method, the contact resistance is
measured several (5-10) times, and the variance of the measurements is
determined. An increase in the variance indicates deteriorating performance.
Replace Relays after Defined Number of Operations. Relays can be
replaced after a predetermined number of contact closures. However, this
method requires knowledge of the applied load and life specifications for
the applied load. For the multiplexers, maximum relay life is specified to be
108 operations at no load or 107 operations at rated load.
14 General Information
Chapter 1
Replacement
Strategy
NOTE
The replacement strategy also depends on the application. If some relays are
used more often, or at higher load, than the others, the relays can be
individually replaced as needed. If all of the relays see similar loads and
switching frequencies, then replace the entire circuit board when the relay
end-of-life approaches. The sensitivity of the application should be weighed
against the cost of replacing relays with some useful life remaining.
Relays that wear out normally or fail due to misuse should not be considered
defective and are not covered by the product’s warranty.
Multiplexer Descriptions
The relay multiplexers are "instruments" in the slots of a VXIbus
mainframe. As such, a multiplexer is assigned an error queue, input and
output buffers, and a status register.
NOTE
Instruments are based on the logical addresses of the plug-in modules. Refer
to the configuration guide provided with your system for information on
setting the addresses to create an instrument.
E1343A/44A
Descriptions
Both modules provide sixteen 3-wire or eight 4-wire multiplexer channels
and can switch voltages up to 250VDC or VACrms. The E1344A provides
a thermistor reference junction on the terminal card for thermocouple
measurements. Both modules use the E1343A relay component module but
they have different terminal card assemblies.
E1345A/47A
Descriptions
The E1345A and E1347A multiplexers provide multiplexing for up to 16
channels (channels 00 through 15). Each channel has HIGH (H), LOW (L),
and GUARD (G) connections. The two multiplexers are identical, except
that the E1347A terminal card assembly adds a thermistor for temperature
measurement applications.
E1355A/56A
Descriptions
The E1355A and E1356A strain gage multiplexers (when used with a
multimeter) provide static and dynamic strain measurement capabilities.
Each multiplexer provides switching (multiplexing) for up to 8 channels
(channels 00 through 07). Each channel has HIGH (H), LOW (L), GUARD
(G), +E, -E1, and -E2 connections. The two multiplexers are identical,
except that the E1355A uses 120Ω bridge resistors, and the E1356A uses
350Ω bridge resistors.

Verification Tests
Introduction
This chapter describes the verification tests for the E1343A, E1344A,
E1345A, E1347A, E1355A, E1356A Relay Multiplexers. The three levels
of test procedures described in this chapter are used to verify that the
modules:
• are functional (Functional Verification Test)
• meet selected testable specifications (Operation
Verification)
• meet all testable specifications (Performance Verification)
Test Conditions &
Procedures
See Table 1-1 for test equipment requirements. You should complete the
Performance Verification tests at least once a year. For heavy use or severe
operating environments, perform the tests more often. The verification tests
assume that the person performing the tests understands how to operate the
mainframe, the multiplexers, and the specified test equipment. The test
procedures do not specify equipment settings for test equipment except in
general terms. It is assumed that a qualified, service-trained technician will
select and connect the cables, adapters, and probes required for the test.
Performance Test
Record
The results of each Performance Verification test may be recorded in
Table 2-2, "Performance Test Record," at the end of this chapter. You
may photocopy this form, if desired.
Verification Test
Examples
Each verification test procedure includes an example program that performs
the test. All example programs assume the following configuration:

Verification Tests 21
Functional Verification Test
The Functional Verification Test for the multiplexer modules consists of
sending the *IDN? command and checking the response. This test can be
used to verify that the multiplexer is connected properly and is responding
to a basic command.
Procedure
1. Verify that the multiplexer is properly installed in mainframe
2. Verify that the mainframe has passed its power-on test.
3. Send *IDN? to the multiplexer (see example following)
4. The return should be as follows (revision number may vary):
HEWLETT-PACKARD,SWITCHBOX,0,A.06.00
NOTE
Example
If the primary address setting, secondary address setting, or the interface
select code is set incorrectly, the multiplexer will not respond. Verify
proper address selection before troubleshooting.
An example follows which uses an HP 9000 Series 300 computer with
HP BASIC and a multiplexer address of 70914.

Operation Verification Test
The procedures in this section are used to provide a high level of confidence
that the multiplexer is meeting published specifications. The Operation
Verification Test is a subset of the Performance Verification Tests and is
suitable for checkout after performing repairs.
The Operation Verification Test is performed by completing the Closed
Channel Resistance Test (Test 2-1) as described in the Performance
Verification Test procedures. This test is usually sufficient to verify that the
multiplexer is meeting its specifications.
22 Verification Tests
Chapter 2
Performance Verification Tests
The procedures in this section are used to test the multiplexer’s electrical
performance using the specifications as the performance standards.
There are two performance verification tests for the relay multiplexers:
Test 2-1: Closed-Channel Resistance Test, and Test 2-2: DC Isolation Test.
These tests are suitable for incoming inspection, troubleshooting, and
preventive maintenance.
Wiring the Test
Fixture
A test fixture is required for the Performance Verification Tests. Figure 2-1
shows typical connections using a terminal module (aka "terminal block")
for the test fixture. You may want to order an extra terminal module to use
as a test fixture so that you don’t have to re-wire each time the tests are
performed. The E1345A terminal module may be used to test the
E1343A/45A/55A and 56A. The terminal module part number is
E1345-80001. The E1347A terminal module may be used to test the
E1344A and 47A. The terminal module part number is E1347-80001.
However, in most cases the E1345-80001 is adequate for testing any or all
of the relay multiplexer component modules.
Figure 2-1. Typical Test Fixture Connections
Chapter 2
Verification Tests 23
Test 2-1: Closed Channel Resistance Test
This test verifies that all relay contacts meet the closed-channel resistance
specification for the multiplexer. If the closed-channel resistance of any
relay contact is greater than 2Ω, the relay should be replaced. This test uses
the test fixture (see Figure 2-1).
Measuring Protection
Resistors
NOTE
Since there are 100Ω protection resistors (R20 through R31) in the relay
paths, measure the protection resistor values to begin this test. The values of
the protection resistors are then subtracted from the measured path
resistance to determine the relay contact resistance. To measure the
protection resistor values, set the 3458A DMM to 4-wire ohms, autorange
and measure each resistor value with the DMM (see Figure 2-2). Record the
measured values in Table 2-1.
On the E1343A and E1344A, Resistors R22, R25, R28, and R31 are 1.0kΩ
resistors.

NOTE
The following program performs a Closed Channel Resistance Test on
Channels 00 - 15 and 90 - 92 HI, LO, and GU. If the contact resistance for a
channel is >2.0 Ω, the program displays the message "Resistance for
Channel chan Relay is >2.0 Ohms" and stops.
Since small measurement variations occur when measuring the protection
resistors, the program returns "0.00" if the calculated resistance is <0 Ω.

Test 2-2: DC Isolation Test
This test verifies that sufficient DC isolation exists at various points on the
multiplexer. DC Isolation is checked from HI to Chassis, HI to LO, and HI
to GU (GUARD). This test uses the test fixture (see Figure 2-1).
NOTE
Chapter 2
The DMM used should be capable of measuring at least 1 GΩ. If the DMM
indicates an overload, record the reading as >Rmax, where Rmax is the
highest resistance that the DMM can measure. For example, if the DMM is
an 3458A, a typical return for an overload is 1.E+38 and the entry in Table
2-2 should be >1.2 GΩ.
Verification Tests 33
HI to Chassis Isolation
1. Make hardware connections as shown in Figure 2-9
2. Set DMM to 2-wire ohms, 1 GΩ range
3. Send CLOS (@nn00:nn15, nn90:nn93) to close all relays
4. Trigger the DMM with TRIG SGL
5. Record the DMM reading on Table 2-2 (HI to Chassis)
Figure 2-9. HI to Chassis Isolation Connections
HI to LO Isolation
1. Make hardware connections as shown in Figure 2-10
2. Trigger the DMM with TRIG SGL

Performance Test Record
Table 2-2, "Performance Test Record," is a form you may copy and use to
record performance verification test results for the multiplexers. Table 2-2
shows multiplexer test limits, DMM measurement uncertainty, and test
accuracy ratio (TAR) values.
Test Limits
Measurement
Uncertainty
Closed Channel
Resistance Test
Test limits are defined for relay closed channel resistance and DC isolation
using the specifications in the individual module’s User’s Manual. The relay
contact resistance and DC isolation specifications are single-ended, meaning
that there is an upper limit OR a lower limit, but not both. In Table 2-2, the
Minimum or Maximum column is blank for a single-sided test.
For the performance verification tests in this manual, measurement
uncertainties are calculated based on the 3458A Digital Multimeter.
The measurement uncertainty shown in Table 2-2 is the accuracy of the
3458A using 90-day specifications. The calculations follow.
Conditions:
• 4-wire ohms function, 10 Ω range
• 90-day specifications
• Worst-case reading = 2.0 Ω
M.U. = (15 ppm of Reading + 5 ppm of Range)
= (15×10−6 ⋅ 2.0 + 5×10−6 ⋅ 10) (Ω)
_
= _________
8.0×10−5 Ω
DC Isolation Test
Conditions:
• 2-wire ohms function, 1 GΩ range
• 90-day specifications
• Worst-case reading = 1.2 GΩ (highest resistance that can
be measured with the 3458A)
M.U. = (0.5% of Reading + 10ppm of Range)
= (0.005 ⋅ 1.2×109 + 10×10−6 ⋅ 1×109) (Ω)
6
________
Ω
_
= 6.0×10
Test Accuracy Ratio
(TAR)
Chapter 2
Test Accuracy Ratios (TAR) are not defined for single-sided measurements,
so all closed-channel resistance and DC isolation measurements show NA
(Not Applicable) in the TAR column.

• Table 3-4 shows reference designators for parts in Tables 3-2 and 3-3.
To order a part listed in Tables 3-2 and 3-3, specify the Agilent
part number and the quantity required. Send the order to your nearest Agilent
Technologies Sales and Service Office.
NOTE
If your multiplexer has a serial number lower than what is listed above, see
Appendix B, "Backdating Information," for replaceable parts ordering information.
Replaceable Parts List
See the Parts Locator diagram (Figure 3-1) for locations of replaceable parts.
See Table 3-1 for replacement part numbers for the Component Assemblies
and Terminal Modules. A relay multiplexer consists of a Component
Assembly and a Terminal Module.
A Terminal Module consists of a Terminal Card and a Terminal Case
Assembly. For example, to order an E1345A Terminal Module, use
E1345-80001. To order only the Terminal Card, use E1345-66510.
To order only the Terminal Case Assembly, use E1300-84401.

E1343A/44A
Multiplexer
Descriptions
The E1343A 16-Channel High Voltage Relay Multiplexer and the E1344A
16-Channel High Voltage Relay Multiplexer (with thermocouple
compensation) modules consist of an E1343A component assembly (part
number E1343-66201) and a terminal module. Each multiplexer provides
switching (multiplexing) of up to 16 channels (channels 00 to 15). Each
channel has HIGH (H), LOW (L), and GUARD (G) connections. See Figure
4-1 for a block diagram of these modules.
The component assembly is the same for the E1343A and E1344A. The
only difference between the two component assemblies is their module ID
jumper settings. The E1343A uses an E1343-80001 terminal assembly and
the E1344A uses an E1344-80001 terminal assembly.
Component Assembly
Description
The E1343A Component Assembly consists of 16 channel relays and four
tree switch relays. The channel relay switches are separated into two banks,
Bank 0 (channels 00 through 07) and Bank 1 (channels 08 to 15). Each bank
has its own common H, L, and G terminals that connect to the channel
switches.
The Bank 0 channel switches also connect to the AT Tree Switch Terminals
(on the terminal module) via the AT Tree Switch (Channel 90) and three
protection resistors (R26, R27, and R28). The Bank 1 channel switches
connect to the BT Tree Switch terminals (on the terminal module) via the
BT Tree Switch (Channel 91) and three protection resistors (R29, R30, and
R31).
The AT2 Tree Switch (Channel 92) connects Bank 1 channels to the AT
Tree Switch. For the E1347A only, the RT Tree Switch (Channel 93)
connects the thermistor (on the terminal module) to the Bank 1 channel
common. This allows measurement of the thermistor to compensate for
temperature measurements made with thermocouples.
The AT Tree Switch connects to the H, L, and G connections on the Analog
Bus Connector and the BT Tree Switch connects to the I+, I-, and IG
connections on the Analog Bus Connector. The Analog Bus Connector
provides direct channel connections between multiple multiplexer modules
and connections between a multiplexer module and E1326/E1411
multimeters.
Each Bank 0 and Bank 1 Common line and AT and BT Tree Switch line has
a 100Ω resistor in series to provide relay contact protection. The Analog
Bus Connector also has six 100Ω resistor in series to provide current
protection.
Terminal Module
Description
50 Service
The terminal module provides connections from user devices to the
multiplexer. The terminal module also provides connections for
multimeters, voltmeters, counters, and other measuring devices. For the
E1344A only, a thermistor is mounted on the terminal module.
Chapter 4
Terminal module connections include H, L, and G terminals for Channels
00 - 15, Bank 0 and Bank 1 Commons, and the AT and BT Tree Switches.
In addition, each channel H line has a jumper on the terminal module that
can be removed to add filter components, attenuators, or current shunts.
E1345A/47A
Multiplexer
Descriptions
The E1345A 16-Channel Relay Multiplexer and the E1347A 16-Channel
Thermocouple Relay Multiplexer modules consist of an E1345A
component assembly ( E1345-66201) and a terminal module. Each
multiplexer provides switching (multiplexing) of up to 16 channels
(channels 00 to 15). Each channel has HIGH (H), LOW (L),

E1355A/56A Strain
Gage Multiplexer
Descriptions
The E1355A and E1356A multiplexers, together with an E1326B or
E1411B multimeter, provide static and dynamic strain measurement
capabilities for an Agilent 75000 Series B or 75000
Series C VXIbus system.
The E1355A and E1356A multiplexer are B-Size, 8-Channel, 120Ω and
350Ω relay strain gage multiplexers respectively. See Figure 4-2 for a block
diagram of the E1355A 120 Ohm Relay Strain Gage Multiplexer. The
block diagram shows a 1/4 bridge arrangement.
Each strain gage multiplexer provides switching (multiplexing) of up to
eight channels. Each channel has HIGH (H), LOW (L), GUARD (G), +E,
-E1, and -E2 connections to provide 1/4, 1/2, or full bridge arrangements.
See the E1355A - E1358A Strain Gage Multiplexers User’s Manual for a
complete description of strain gage bridge arrangements.
The strain gage multiplexer module consists of a component assembly and a
terminal module. The component assembly is the same for the E1355A and
E1356A multiplexer modules. The only difference between the two
component assemblies is their jumper settings. The E1355A has an
E1355-80001 terminal module and the E1356A has an E1356-80001
terminal module.

Terminal Module
Description
The terminal module contains the set of bridge resistors used in strain gage
measurements. The two 1kΩ bridge resistors contained in the resistor pack
(RP1) make up one half of the bridge arrangement. The other half of the
bridge arrangement for channel 0 consists of a user-supplied 120Ω strain
gage and the 120Ω resistor R0.
The junction (Vg) between the resistors R21 and R20 is known as a Wagner
Ground. The purpose of the Wagner Ground is to reduce stray leakage
currents when the Guard lead (G) is connected to the specimen being
measured.

Troubleshooting Techniques
To troubleshoot a relay multiplexer problem, you must first identify the
problem and then isolate the cause of the problem to a replaceable part. See
Chapter 3, "Replaceable Parts," or Appendix B, "Backdating Information,"
for descriptions and locations of replaceable parts, depending on the serial
number of your multiplexer.
NOTE
Identifying the
Problem
If the problem cannot be isolated to a user-replaceable part, we suggest you
return the multiplexer to Hewlett-Packard for repair, or order a replacement
assembly. See Chapter 1, "General Information," for procedures to return
multiplexers to Hewlett-Packard. See Chapter 3, "Replaceable Parts," for
information on ordering replaceable parts.
Table 4-2 lists some common problems for the relay multiplexers, along
with symptoms and possible solutions. If the problem cannot be identified
using these steps, perform component-level troubleshooting using the parts
locator diagram in Chapter 3 (Figure 3-1) and the schematic diagrams
located at the back of this manual.

You can use the tests and checks in Chapter 2, "Verification Tests," and the
information in Table 4-4 to isolate the problem to a relay, to a component,
or both. For example, if Test 2-1: Closed Channel Resistance Test failed
for channel 0, replace relay K100, etc. See Chapter 3, "Replaceable Parts,"
or Appendix B, "Backdating Information," for replaceable parts lists and
locator diagrams, depending on the serial number of your multiplexer.

Repair and Maintenance Guidelines
This section provides guidelines for handling the relay multiplexers
including:
• ESD precautions
• Soldering printed circuit boards
• Post-repair safety checks
ESD Precautions
Electrostatic discharge (ESD) may damage static sensitive devices in the
multiplexers. This damage can range from slight parameter degradation to
catastrophic failure. When handling multiplexer assemblies, observe the
following guidelines to avoid damaging multiplexer components:
• Always use a static-free work station with a pad of conductive rubber
or similar material when handling multiplexer components.
• If a device requires soldering, be sure the assembly is placed on a
pad of conductive material. Also, be sure that you, the pad, and the
soldering iron tip are grounded to the assembly.
Soldering Printed
Circuit Boards
Some of the components on the etched circuit boards of the multiplexer
modules have plated through-holes that provide a solder path to both sides
of the insulating material. Soldering can be done from either side of the
board with equally good results. When soldering to any circuit board, keep
in mind the following guidelines:
• Avoid unnecessary component unsoldering and soldering. Excessive
replacement can result in damage to the circuit board, adjacent
components, or both.
• Do not use a high power soldering iron on etched circuit boards, as
excessive heat may lift a conductor or damage the board.
• Use a suction device or wooden toothpick to remove solder from
component mounting holes. When using a suction device, be sure
that the equipment is properly grounded.
Post-Repair Safety
Checks
Chapter 4
After making repairs to the multiplexer, inspect the multiplexer for any
signs of abnormal internally generated heat, such as discolored printed
circuit boards or components, damaged insulation, or evidence of arcing.
Determine and correct the cause of the condition. Then perform the
functional tests as described in Chapter 2, "Verification Tests," to verify that
the multiplexer is functional.
