Step 11. Avoid Costly Repairs
Step 11. Avoid Costly Repairs
CAUTION
Electrical channel input circuits and the trigger input circuit can be damaged
by electrostatic discharge (ESD). Therefore, avoid applying static discharges
to the front-panel input connectors. Prior to connecting any coaxial cable to
the connectors, momentarily short the center and outer conductors of the
cable together. Avoid touching the front-panel input connectors without first
touching the frame of the instrument. Be sure that the instrument is properly
earth-grounded to prevent buildup of static charge. Wear a wrist-strap or heelstrap.
CAUTION
Optical channel fiber-optic connectors are easily damaged when connected to
dirty or damaged cables and accessories. When you use improper cleaning and
handling techniques, you risk expensive instrument repairs, damaged cables,
1-24

and compromised measurements. Before you connect any fiber-optic cable to
the Infiniium DCA, refer to “Cleaning Connections for Accurate
Measurements” on page 1-30.
1-25
Setting Up the Infiniium DCA
Step 12. Perform a Module Calibration
Step 12. Perform a Module Calibration
A module calibration establishes calibration factors for all installed modules.
The calibration factors compensate for imperfections in the measurement system (for example, variations due to ambient temperature), resulting in the
best instrument precision. It is recommended that you perform this calibration
routinely for best measurement accuracy.
The module calibration is recommended whenever the following occurs:
• Instrument power has been cycled
• A module has been removed and then reinserted
• A change in the temperature of the mainframe exceeds 5°C compared to the
temperature of the last vertical (amplitude) calibration (∆T > 5°C)
• The time since the last calibration has exceeded 10 hours
Refer to the Help for more information about instrument calibrations.
Warm-up time
Allow the instrument, with modules installed, to warm up for a period of at least one
hour before performing a vertical calibration. This ensures that the module reaches its
equilibrium temperature.
CAUTION
Electrical channel input circuits and the trigger input circuit can be damaged
by electrostatic discharge (ESD). Therefore, avoid applying static discharges
to the front-panel input connectors. Prior to connecting any coaxial cable to
the connectors, momentarily short the center and outer conductors of the

Cleaning Connections for Accurate Measurements
Cleaning Connections for Accurate
Measurements
Today, advances in measurement capabilities make connectors and connection techniques more important than ever. Damage to the connectors on calibration and verification devices, test ports, cables, and other devices can
degrade measurement accuracy and damage instruments. Replacing a damaged connector can cost thousands of dollars, not to mention lost time! This
expense can be avoided by observing the simple precautions presented in this
book. This book also contains a brief list of tips for caring for electrical connectors.
Choosing the Right Connector
A critical but often overlooked factor in making a good lightwave measurement is the selection of the fiber-optic connector. The differences in connector types are mainly in the mechanical assembly that holds the ferrule in
position against another identical ferrule. Connectors also vary in the polish,
curve, and concentricity of the core within the cladding. Mating one style of
cable to another requires an adapter. Agilent Technologies offers adapters for
most instruments to allow testing with many different cables. Figure 1-1 on
page 1-31 shows the basic components of a typical connectors.
The system tolerance for reflection and insertion loss must be known when
selecting a connector from the wide variety of currently available connectors.
Some items to consider when selecting a connector are:
• How much insertion loss can be allowed?
• Will the connector need to make multiple connections? Some connectors are
better than others, and some are very poor for making repeated connections.
• What is the reflection tolerance? Can the system take reflection degradation?
• Is an instrument-grade connector with a precision core alignment required?
• Is repeatability tolerance for reflection and loss important? Do your specifica-

Setting Up the Infiniium DCA
Choosing the Right Connector
tions take repeatability uncertainty into account?
• Will a connector degrade the return loss too much, or will a fusion splice be required? For example, many DFB lasers cannot operate with reflections from
connectors. Often as much as 90 dB isolation is needed.
Figure 1-1. Basic components of a connector.
Over the last few years, the FC/PC style connector has emerged as the most
popular connector for fiber-optic applications. While not the highest performing connector, it represents a good compromise between performance, reliability, and cost. If properly maintained and cleaned, this connector can
withstand many repeated connections.
However, many instrument specifications require tighter tolerances than most
connectors, including the FC/PC style, can deliver. These instruments cannot
tolerate connectors with the large non-concentricities of the fiber common
with ceramic style ferrules. When tighter alignment is required, Agilent
Technologies instruments typically use a connector such as the Diamond
HMS-10, which has concentric tolerances within a few tenths of a micron. Agilent Technologies then uses a special universal adapter, which allows other
cable types to mate with this precision connector. See Figure 1-2.
1-31
Setting Up the Infiniium DCA
Choosing the Right Connector
Figure 1-2. Universal adapters to Diamond HMS-10.
The HMS-10 encases the fiber within a soft nickel silver (Cu/Ni/Zn) center
which is surrounded by a tough tungsten carbide casing, as shown in
Figure 1-3.
Figure 1-3. Cross-section of the Diamond HMS-10 connector.
The nickel silver allows an active centering process that permits the glass fiber
to be moved to the desired position. This process first stakes the soft nickel
silver to fix the fiber in a near-center location, then uses a post-active staking
to shift the fiber into the desired position within 0.2 µm. This process, plus the
keyed axis, allows very precise core-to-core alignments. This connector is
found on most Agilent Technologies lightwave instruments.
The soft core, while allowing precise centering, is also the chief liability of the
connector. The soft material is easily damaged. Care must be taken to minimize excessive scratching and wear. While minor wear is not a problem if the

glass face is not affected, scratches or grit can cause the glass fiber to move
out of alignment. Also, if unkeyed connectors are used, the nickel silver can be
pushed onto the glass surface. Scratches, fiber movement, or glass contamination will cause loss of signal and increased reflections, resulting in poor return
loss.
Inspecting Connectors
Because fiber-optic connectors are susceptible to damage that is not immediately obvious to the naked eye, bad measurements can be made without the
user even being aware of a connector problem. Although microscopic examination and return loss measurements are the best way to ensure good connections, they are not always practical. An awareness of potential problems, along
with good cleaning practices, can ensure that optimum connector performance is maintained. With glass-to-glass interfaces, it is clear that any degradation of a ferrule or the end of the fiber, any stray particles, or finger oil can
have a significant effect on connector performance.
Figure 1-4 shows the end of a clean fiber-optic cable. The dark circle in the
center of the micrograph is the fiber’s 125 µm core and cladding which carries
the light. The surrounding area is the soft nickel-silver ferrule. Figure 1-5
shows a dirty fiber end from neglect or perhaps improper cleaning. Material is
smeared and ground into the end of the fiber causing light scattering and poor
reflection. Not only is the precision polish lost, but this action can grind off the
glass face and destroy the connector.
Figure 1-6 shows physical damage to the glass fiber end caused by either
repeated connections made without removing loose particles or using
improper cleaning tools. When severe, the damage on one connector end can
be transferred to another good connector that comes in contact with it.
The cure for these problems is disciplined connector care as described in the
following list and in “Cleaning Connectors” on page 1-36.
Use the following guidelines to achieve the best possible performance when
making measurements on a fiber-optic system:
• Never use metal or sharp objects to clean a connector and never scrape the
connector.
• Avoid matching gel and oils.

Figure 1-6. Damage from improper cleaning.
While these often work well on first insertion, they are great dirt magnets. The
oil or gel grabs and holds grit that is then ground into the end of the fiber.
Also, some early gels were designed for use with the FC, non-contacting con1-34
Setting Up the Infiniium DCA
Inspecting Connectors
nectors, using small glass spheres. When used with contacting connectors,
these glass balls can scratch and pit the fiber. If an index matching gel or oil
must be used, apply it to a freshly cleaned connector, make the measurement,
and then immediately clean it off. Never use a gel for longer-term connections
and never use it to improve a damaged connector. The gel can mask the extent
of damage and continued use of a damaged fiber can transfer damage to the
instrument.
• When inserting a fiber-optic cable into a connector, gently insert it in as
straight a line as possible. Tipping and inserting at an angle can scrape material
off the inside of the connector or even break the inside sleeve of connectors
made with ceramic material.
• When inserting a fiber-optic connector into a connector, make sure that the fiber end does not touch the outside of the mating connector or adapter.
• Avoid over tightening connections.
Unlike common electrical connections, tighter is not better. The purpose of
the connector is to bring two fiber ends together. Once they touch, tightening
only causes a greater force to be applied to the delicate fibers. With connectors that have a convex fiber end, the end can be pushed off-axis resulting in
misalignment and excessive return loss. Many measurements are actually
improved by backing off the connector pressure. Also, if a piece of grit does
happen to get by the cleaning procedure, the tighter connection is more likely
to damage the glass. Tighten the connectors just until the two fibers touch.
• Keep connectors covered when not in use.
• Use fusion splices on the more permanent critical nodes. Choose the best connector possible. Replace connecting cables regularly. Frequently measure the
return loss of the connector to check for degradation, and clean every connector, every time.
All connectors should be treated like the high-quality lens of a good camera.
The weak link in instrument and system reliability is often the inappropriate
use and care of the connector. Because current connectors are so easy to use,
there tends to be reduced vigilance in connector care and cleaning. It takes
only one missed cleaning for a piece of grit to permanently damage the glass
and ruin the connector.
Measuring insertion loss and return loss
Consistent measurements with your lightwave equipment are a good indication that you have good connections. Since return loss and insertion loss are
key factors in determining optical connector performance they can be used to
determine connector degradation. A smooth, polished fiber end should pro-
1-35
Setting Up the Infiniium DCA
Cleaning Connectors
duce a good return-loss measurement. The quality of the polish establishes
the difference between the “PC” (physical contact) and the “Super PC” connectors. Most connectors today are physical contact which make glass-to-glass
connections, therefore it is critical that the area around the glass core be clean
and free of scratches. Although the major area of a connector, excluding the
glass, may show scratches and wear, if the glass has maintained its polished
smoothness, the connector can still provide a good low level return loss connection.
If you test your cables and accessories for insertion loss and return loss upon
receipt, and retain the measured data for comparison, you will be able to tell in
the future if any degradation has occurred. Typical values are less than 0.5 dB
of loss, and sometimes as little as 0.1 dB of loss with high performance connectors. Return loss is a measure of reflection: the less reflection the better
(the larger the return loss, the smaller the reflection). The best physically
contacting connectors have return losses better than 50 dB, although 30 to
40 dB is more common.
Visual inspection of fiber ends
Visual inspection of fiber ends can be helpful. Contamination or imperfections
on the cable end face can be detected as well as cracks or chips in the fiber
itself. Use a microscope (100X to 200X magnification) to inspect the entire
end face for contamination, raised metal, or dents in the metal as well as any
other imperfections. Inspect the fiber for cracks and chips. Visible imperfections not touching the fiber core may not affect performance (unless the
imperfections keep the fibers from contacting).
Cleaning Connectors
The procedures in this section provide the proper steps for cleaning fiberoptic cables and Agilent Technologies universal adapters. The initial cleaning,
using the alcohol as a solvent, gently removes any grit and oil. If a caked-on
layer of material is still present, (this can happen if the beryllium-copper sides
of the ferrule retainer get scraped and deposited on the end of the fiber during
insertion of the cable), a second cleaning should be performed. It is not
uncommon for a cable or connector to require more than one cleaning.
CAUTION
Agilent Technologies strongly recommends that index matching compounds
not be applied to their instruments and accessories. Some compounds, such as
gels, may be difficult to remove and can contain damaging particulates. If you
think the use of such compounds is necessary, refer to the compound
manufacturer for information on application and cleaning procedures.

To clean a non-lensed connector
CAUTION
Do not use any type of foam swab to clean optical fiber ends. Foam swabs can
leave filmy deposits on fiber ends that can degrade performance.
1 Apply pure isopropyl alcohol to a clean lint-free cotton swab or lens paper.
Cotton swabs can be used as long as no cotton fibers remain on the fiber end
after cleaning.
2 Clean the ferrules and other parts of the connector while avoiding the end of
the fiber.
3 Apply isopropyl alcohol to a new clean lint-free cotton swab or lens paper.
4 Clean the fiber end with the swab or lens paper.
Do not scrub during this initial cleaning because grit can be caught in the
swab and become a gouging element.
5 Immediately dry the fiber end with a clean, dry, lint-free cotton swab or lens
paper.

filtered, dry, compressed air. Aim the compressed air at a shallow angle to the
fiber end face.
Nitrogen gas or compressed dust remover can also be used.
CAUTION
Do not shake, tip, or invert compressed air canisters, because this releases
particles in the can into the air. Refer to instructions provided on the
compressed air canister.
7 As soon as the connector is dry, connect or cover it for later use.
If the performance, after the initial cleaning, seems poor try cleaning the connector again. Often a second cleaning will restore proper performance. The
second cleaning should be more arduous with a scrubbing action.
To clean an adapter
The fiber-optic input and output connectors on many Agilent Technologies
instruments employ a universal adapter such as those shown in the following
picture. These adapters allow you to connect the instrument to different types
of fiber-optic cables.
Figure 1-7. Universal adapters.
1 Apply isopropyl alcohol to a clean foam swab.
Cotton swabs can be used as long as no cotton fibers remain after cleaning. The
foam swabs listed in this section’s introduction are small enough to fit into
adapters.
Although foam swabs can leave filmy deposits, these deposits are very thin, and
the risk of other contamination buildup on the inside of adapters greatly outweighs the risk of contamination by foam swabs.
2 Clean the adapter with the foam swab.
3 Dry the inside of the adapter with a clean, dry, foam swab.
4 Blow through the adapter using filtered, dry, compressed air.
Nitrogen gas or compressed dust remover can also be used. Do not shake, tip,
or invert compressed air canisters, because this releases particles in the can
into the air. Refer to instructions provided on the compressed air canister.

Working in Comfort
To optimize your comfort and productivity, it is important that you set up your
work area correctly and use your Agilent product properly. With that in mind,
we have developed some setup and use recommendations for you to follow
based on established ergonomic principles.
Improper and prolonged use of keyboards and input devices are among those
tasks that have been associated with repetitive strain injury (RSI) to soft tissues in the hands and arms. If you experience discomfort or pain while using
your Agilent Technologies product, discontinue use immediately and consult
your physician as soon as possible.
Please study the recommendations offered here in this chapter. You may also
wish to consult your employer’s human resources department or other relevant departments for guidance specific to your company.
About Repetitive Strain Injury
Because your comfort and safety are our primary concern, we strongly recommend that you use the infiniium DCA in accordance with established ergonomic principles and recommendations. Scientific literature suggests that
there may be a relationship between injury to soft tissues - especially in the
hands and arms - and prolonged improper use of keyboards or other equipment requiring repeated motions of the hands and forearms. This literature
also suggests that there are many other risk factor that may increase the
chance of such injury, commonly called Repetitive Strain Injury.
What is RSI?
Repetitive Strain Injury (RSI—also known as cumulative trauma disorder or
repetitive motion injury) is a type of injury where soft tissues in the body, such
as muscles, nerves, or tendons, become irritated or inflamed. RSI has been a
reported problem for those who perform repetitive tasks such as assembly line
work, meatpacking, sewing, playing musical instruments, and computer work.
2-2
Working in Comfort
Mice and Other Input Devices
RSI has also been observed in those who frequently engage in activities such
as carpentry, knitting, housework, gardening, tennis, windsurfing and lifting
children.
What causes RSI?
The specific causes of RSI have not been established. Nevertheless, the incidence of RSI has been associated with a variety of risk factors, including:
• Too many uninterrupted repetitions of an activity or motion.
• Performing an activity in an awkward or unnatural posture.
• Maintaining a static position for prolonged periods.
• Failing to take frequent short breaks.
• Other environmental and social factors.
In addition, there have been reports associating the occurrence of RSI with
the use of keyboards, mice, and other input devices. Also, certain medical conditions, such as rheumatoid arthritis, obesity and diabetes, may predispose
people to this type of injury.
What if I
experience
discomfort?
If you are experiencing any discomfort, seek professional medical advice
immediately. Typically, the earlier a problem is diagnosed and treated, the easier it is to resolve.
Mice and Other Input Devices
Various aspects of using mice and other input devices may increase your risk
of discomfort or injury. Observing the following recommendations may reduce
that risk.
• Try to keep your hand, wrist, and forearm in a neutral position while using your
mouse or other input device.
• If you use your thumb to rotate the ball on a trackball or spaceball, keep it in a
relaxed, natural shape, and maintain a neutral posture in your hand, wrist, and
forearm.
• Hold the mouse gently by draping your fingers over it. Keep your hand relaxed
and fingers loose. Do not grip the mouse tightly.
• It takes very little pressure or force from your fingers to activate the buttons or
scroll wheel on your mouse, scrolling mouse, trackball, or other input device.
Using too much force can place unnecessary stress on the tendons and muscles
2-3
Working in Comfort
Mice and Other Input Devices
in your hands, wrists, and forearms.
• If you are using a scrolling mouse, be sure to keep your fingers and hand in a
relaxed, neutral position when activating the scroll wheel. Also, this type of
mouse features software that can minimize the number of mouse movements
or button clicks.
• When using a mouse, trackball, or other input device, position it as close to the
keyboard as possible, and keep it at the same level as you do not have to stretch
while using it.
• Use a good quality mouse pad to enable the mouse to work most effectively and
reduce unnecessary hand and wrist movements.
• Be sure to keep your mouse and trackball clean. Regular removal of accumulated dust and dirt helps ensure proper tracking and reduces unnecessary hand
and wrist motions.

You must provide a trigger input signal
Because high-speed oscilloscopes are not capable of triggering directly on a
test signal, you must first connect an external timing reference signal to the
front-panel trigger input connector. This input allows the Infiniium DCA to
synchonize to the input signal. You can select free-run triggering when an
external trigger is unavailable. However, you will only be able to view the
waveform for amplitude information only without any timing information. This
is an easy way to examine the amplitude of a signal.

Eye/Mask Mode
The Eye/Mask mode allows you to perform NRZ (Non-Return to Zero), or RZ
(Return to Zero) eye diagram measurements and eye mask tests. The eye diagram is typically produced by triggering
the instrument with a synchronous
clock signal.
Eye/Mask mode measurements only
work when an eye diagram, and not a
pulse, is present on the screen. Measurements made on a pulse waveform
while in Eye/Mask mode will fail.
Once you are in Eye/Mask mode, press the Autoscale button. This ensures
that an optimum eye diagram is displayed on the graticule. An optimum eye
diagram consists of a full display of the eye in addition to portions of the waveform preceding and following the eye.
When you select the Eye/Mask mode, the
measurement toolbars shown here appear.
These measurement toolbars include measurements such as rise time, fall time, jitter,
and extinction ratio, as well as the mask test
start and stop controls.
Eye measurement and mask test results
appear below the display graticule. A maximum of four eye measurement test results
are displayed and include any failures or

include measurements such as rise time, fall
time, overshoot, and Vp-p. All measurements, with the exception of jitter, can be
performed on any of the following sources:
channels, waveform memories, and math
functions. One of the above sources must be
turned on in order to perform an oscilloscope measurement.
If more than one source is turned on and
you initiate a measurement, the Enter Measurement Info dialog box opens. This dialog

Using Plug-in Modules
You can use 8348x and 5475x series plug-in modules
In addition to a complete line of modules designed specifically for this instrument, modules designed for use with HP/Agilent 83480A and 54750A mainframes can also be installed into the Infiniium DCA. The 8348x and 5475x
series plug-in modules are equipped with a trigger input on the individual
module front panels. Repeatedly press the Infiniium DCA’s front-panel Trigger
Source button until the label for the desired trigger source is lit.
CAUTION
Electrical channel input circuits and the trigger input circuit can be damaged
by electrostatic discharge (ESD). Avoid applying static discharges to the frontpanel input connectors. Prior to connecting any coaxial cable to the
connectors, momentarily short the center and outer conductors of the cable
together. Avoid touching the front-panel input connectors without first
touching the frame of the instrument. Be sure that the instrument is properly
earth-grounded to prevent buildup of static charge. Wear a wrist-strap or heelstrap.
CAUTION
Optical channel fiber-optic connectors are easily damaged when connected to
dirty or damaged cables and accessories. When you use improper cleaning and
handling techniques, you risk expensive instrument repairs, damaged cables,
and compromised measurements. Before you connect any fiber-optic cable to
the digital communications analyzer, refer to “Cleaning Connections for
Accurate Measurements” on page 1-30.
