General Info rmation
This manual contains inform at ion required to test, trouble shoot, and repai r
the Agilent E1463A 32-Channel Form C Switc h Module (see Figure 1-1).

Chapter 1General Information 9
Relay Life
Electromechanical relays are subject to normal wear-out. Relay life
depends on several factors. The effects of loading and switching
frequency are briefly discussed below:
Relay Load. In gen eral, hi ghe r powe r switching reduces relay life . In
addition, capa c it ive /inductive loa ds a nd hi gh inrush currents (e .g ., whe n
turning on a lam p or motor) reduce relay l ife . Exceeding the specified
maximum inputs can cause catastrophic failure.
Switching Frequency. Relay contacts he at up whe n 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 rela y f ai lu re. The en d of the li fe of a rela y c an be determined
using one or more of the thr e e methods described bel ow. T he best me thod
(or combination of methods), as well as the failure criteria, depends on the
applicatio n in which the relay is used.
Contact Resistance. As the relay begins to wear out, its c ont act 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 exce eds 2.0 Ohm.
Stability of Co nt ac t Resistance. The stability o f the co ntac t res ista nce
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.
Number of Operations. Alternatively, relays can be replaced after a
predetermined number of contact closures. How ever, this method
requires knowledge of the applied load and life specifications for the
applied load. For the Agilent E1463A, maximum relay life is specified
at 5 X 10
worst-case rated load.

operations with no load and 3.5 X 104 operations at the
10 General InformationChapter 1
Replacement
Strategy
The replacement strategy also depends on the a pplication. If some
relays are used more often, or a t higher load, tha n the others, the relays
can be individually replaced as needed. If all of the relays see similar
loads and switching frequencies, the entire circuit boar d can be
replaced when the end of life a pproaches. The sensitivity of the
application should be weighed against the cost of replacing relays with
some useful life remaining.
NOTE
Relays that wear out normally or fail due to misuse should not be
considered defective and are not covered by the product’s warranty.
Safety Considerations
This pr oduct is a Saf e ty Class I instrument tha t is provided with a
prote ctive earth t e r minal when installed in th e ma inframe. Th e
instrument, mainf rame, a nd a ll r e la ted docu me ntation sho uld be revie wed
for familiarization with safety markings and instructions before operation
or service.
Refer to the WARNI NGS on pag e 4 i n thi s ma nual for a summary of safe ty
informatio n. Safety informat ion for testing a nd se rvice follows and is al so
found throughout this manual.
WARNINGS and
CAUTIONS
This section co nta i ns W A RNINGS which must be foll owe d f or your
protection and C AUTIONS whi ch must be follo w ed to a voi d da ma ge to t he
equipment when performing instrument maintenance or repair.
WARNING
SERVICE-TRAINED PERSONNEL ONLY. The information in this
manual is for service-trained personnel who are familiar with
electroni c circ u it ry and are aware of th e haz ards involved. To
avoid personal injury or damage to the instrument, do not
perform procedures in this manual or do any servic ing unless
you are qualified to do so.
CHECK MAINFRAME POWER SETTINGS. Before applying
power, verify that the main frame setting matches the line
voltage and that the correct fuse is installed. An uninterruptible
safety earth ground must be provide d from the main power
source to the supplied power cord set.
Chapter 1General Information 11
WARNING
GROUNDING REQUIREMENTS . Interruption of the protective
(grounding) conductor (inside or outside the mainframe) or
disconnecting th e protective earth terminal will cause a
potential shock hazard that coul d result in personal injury.
(Grounding one conductor of a two-conductor outlet is not
sufficient protection.)
IMPAIRED PROTECTION. Whene ve r it is likely tha t inst ru ment
protection has been impaired, the mainframe must be made
inoperative and b e secured against any un intended operation.
REMOVE POWER IF POSSIBLE. Some procedures in this
manual may be performed with power supplied to the
mainframe while p rotective covers ar e 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.)
USING AUTOTRANSFORMERS. If the mainframe is to be
energized via an autotransformer (for voltage reduction) make
sure the common terminal is connected to neutra l (tha t is, the
grounded sid e 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 ag ainst fire
hazard, rep lace th e 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 -circui ted fuseholders.
SHOCK HAZARD. Only service-trained personnel who are
aware of the hazards involved should install, remove, or
configure the Agilent E1463A 32-Cha nnel Form C Switch
Module . Before you remove any installed modul e, disconnect
AC power from the mainframe and from other modules that
may be connecte d to the Switch Module.
CHANNEL WIRING INSULATION. All channels that have a
common connection must be insulated so that the user is
protected from electrical shock. This means wiring for all
channels must be insulated as thoug h each channel carries
the voltage of the highest voltag e chann el.
12 General InformationChapter 1
CAUTION
MAXIMUM INPUTS. The maximum voltage that can be applied to
any terminal is 125 V dc (250 Vac rms). The maximum current per
channel or common is 5 A DC or ac rms. The maximum power that
can be applied to any channel or common is 150 W or 1250 VA.
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
working on the device.

Repair/Maintenance Guidelines
This sectio n provides guideli ne s fo r re pa iring and mainta ining the
Agilent E1463A S witch Module, including:
• ESD precautions
• S oldering printed circuit boards
• Po st-repair safety checks
ESD PrecautionsElectrostatic disc ha r ge (E SD) ma y da ma ge static-sensi tive devices in the
switch mod ule s. T his damage can range f ro m slight parame te r deg rada tion
to catastrophic failure. When handling the switch module assemblies, follow
these guideli ne s to avoid damaging components:
• Always use a static-free work stati on wi th a pa d of con ductive rubber or
similar ma te r ial whe n ha ndling electr oni c com ponents.
• Do not use pliers to remove a MOS or CMOS device from a hi gh-gr ip
socket. Instead, use a small sc rewdr i ve r to pr y the de vice up from one
end. Slowly lift the device up, one pair of pins at a time.
Sold e rin g Pr i n t ed
Circuit Boards
• After you remove a MOS or CMOS device from a module, place the
device onto a pad of conductive foam or ot he r suitable holdi ng ma t eri al .
• If a device requires soldering, be sur e the ass embly is placed on a pad of
conductiv e mat e ria l. Also, be sure that you, the pa d, an d the soldering
iron tip are grounded to the assembly.
The etched circu it boards in the switch module have pla ted- through holes
that allow a solder path to bo th si de s of the insulating ma te r ial. Soldering
can be done from eit he r side of the boa rd with equally goo d results. When
soldering to an y ci rcu it board, keep in mind the following guidelines:
• The relays used on these printed circuit boards require special soldering
techniques and e quipment. The use of a sol de r-p ot is recommended for
relay removal and replacement.
• Do not use a high power soldering iron on e tc he d cir c uit boa r ds, as
excessive heat m ay lift a conductor or damage the boa r d.
• Use a suc t ion de vice or wooden t oothpick to re move so lder from
component mounting holes. Wh en using a suction de vic e , be su re the
equipment is pr operly grounded.

Post-Repair
Safety Checks
After making repa irs to the module, inspect the devi c e for an y signs of
abnormal int erna lly generated he a t, suc h a s dis colored printed c ir c uit boa r ds
or components, dama ge d insulation, or evi de nc e of arci ng. De te r mi ne and
correct the cause of the condition. Then pe r fo rm the Functional Verific a ti o n
Test described in Chapter 2 to verify that the device is functional.
