Working in Comfort

Introduction

To optimize your comfort and productivity, it is important that you set
up your work area correctly and use your Infiniium oscilloscope properly.
With that in mind, we have developed some set-up 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 the oscilloscope, discontinue use immediately and
consult your physician as soon as possible. For more information on RSI
you may wish to consult the About Repetitive Strain Injury section.

Please study the recommendations offered here in this chapter.
Included there are references to relevant parts of international
standards, regulations and guidelines, such as ISO 9241 and the
European Community Display Screen Equipment directive. 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

About Repetitive Strain Injury

Because your comfort and safety are our primary concern, we strongly
recommend that you use the Infiniium oscilloscope 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 factors 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.
RSI also has 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 static posture for prolonged periods.

• Failing to take frequent short breaks.

• Other environmental and psychosocial 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
some 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.

Working in Comfort

Mice and Other Input Devices

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 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.

• 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.

Using the Oscilloscope

Using the Oscilloscope

The Infiniium Oscilloscope is designed to be easy to use.

• The familiar front-panel oscilloscope interface with knobs and keys is
optimized for the most common kinds of troubleshooting tasks and
basic measurements. See “Using the Front Panel” on page 3-3.

• The graphical interface with menus, windows, dialogs, and toolbars
provides easy logical access to dozens of configuration and analysis
tools, making it easy for you to set up and make the most complex
measurements. The interface also allows you to use the Infiniium
oscilloscope’s built-in information system, which gives detailed
information on using the oscilloscope to make measurements. See
“Using the Graphical Interface” on page 3-22.

3-2

Using the Oscilloscope

Using the Front Panel

The Infiniium Oscilloscope front panel has been designed to give you
direct access to the functions needed to perform the most common
measurements needed in troubleshooting, using a traditional
oscilloscope interface. Knobs and keys are included to enable direct
setting of vertical and horizontal parameters. In addition, the front panel
has a set of LED (Light-Emitting Diode) indicators; by using these and
the display, you can assess the configuration of the oscilloscope at a
glance—there is no need to enter a series of keystrokes to navigate
through complex menus.

The Infiniium Oscilloscope uses color consistently throughout the front
panel and user interface. For example, the color of the knob for channel
1 is the same color as the waveform for channel 1. All the configuration
items and values related to channel 1 are displayed in the same color.

Using the Oscilloscope

Acquisition and General Controls

Acquisition and General Controls

Using the acquisition and general controls, you control whether the oscilloscope
is running or stopped. Other keys allow you to reset the oscilloscope to its
default setup, automatically configure the oscilloscope for the current input
signals (Autoscale), or clear the waveforms from the display and reset such
things as measurement statistics and averaging.

Horizontal Controls

Using the horizontal controls, you configure the oscilloscope’s sweep speed
(seconds per division) and horizontal position of the waveform. You can also
view a magnified section of the waveform using the delayed sweep window,
which uses software to expand part of the acquisition memory.

Trigger Controls

Using the trigger controls, you set the conditions on which the oscilloscope will
trigger and acquire an input signal. You can set up a variety of trigger conditions.
Edge and glitch triggers can be selected from the front panel, and the
parameters for edge triggering can be set up here as well. Some glitch trigger
parameters (such as glitch width) and all advanced trigger configurations are
set up using the graphical interface.

Trigger configuration settings you make using the graphical interface are
reflected in the front-panel status indicators, and will remain set unless you
change them (either using the front panel or the graphical interface) or press
the Default Setup key. See “Using the Graphical Interface” on page 3-22 for
information on accessing the graphical interface.

Vertical Controls

Using the vertical controls, you set the vertical scaling (volts per division) and
vertical offset. You can also turn the display on or off for a particular channel.

3-5

Using the Oscilloscope

Marker and Measurement Controls

Marker and Measurement Controls

Using the marker and measurement controls, you control two sets of markers
within the oscilloscope graticule. You use markers to make more accurate
measurements of waveform events than you could make visually. Both time
and voltage differences between the markers are updated continuously on the
screen. By default, the markers track the source waveform. Voltage
measurements from the markers are the value of the waveform at the time set
with the marker arrow keys.

The QuickMeas key initiates five preset measurements on the waveforms. Both
quick measurements and markers will function on any input waveform; simply
continue to press and release one of the keys (either QuickMeas, Marker A, or
Marker B) to cycle through all the waveforms on the screen, then to the off
state. You choose which five measurements will be performed by using the
measurement configuration commands in the graphical interface.

• To stretch the waveform horizontally, turn the sweep speed knob
clockwise. To shrink it horizontally, turn the knob counter-clockwise.

The sweep speed knob is the larger of the two horizontal control knobs. It is
marked with a set of sine wave symbols. Stretching the waveform means there
are fewer seconds displayed per division. Shrinking the waveform means there
are more seconds displayed per division.

• To move the waveform to the right, turn the horizontal position knob
clockwise. To move the waveform to the left, turn the horizontal
position knob counter-clockwise.

Moving the waveform to the right shows more of the pretrigger data (data
acquired before the trigger event). Moving the waveform to the left shows more
of the post-trigger data (data acquired after the trigger event).

The horizontal position knob is the smaller of the two horizontal control knobs.
It is marked with a set of arrows. There is a detent programmed into the
software so there is a momentary pause at zero while you are turning the knob.
Continuing to turn the knob will move the horizontal position through zero.

To use the markers

Markers make it easier to make precise measurements because the marker
measurement readouts show exact voltage and time positions for the markers.
The measurements are based on actual waveform data from the acquisition
system, not on approximations based on the display position, so you can be sure
that the values are highly accurate.

• To turn on Marker A, press the Marker A key.

Marker A has a solid line pattern on the waveform display. It is associated with
the first available source on the display. Press the key again to move to the next
available source. When there are no more sources, the marker turns off.

• To turn on Marker B, press the Marker B key.

Marker B has a dashed line pattern on the waveform display. It is associated
with the first available source on the display. Press the key again to move to
the next available source. When there are no more sources, the marker turns off.

• To move a marker on the waveform, press and hold the left arrow or
right arrow key next to the desired Marker key. Release the key when
the marker is at the desired waveform event.

The marker snaps to and follows the shape of the waveform on the screen. The
voltage value shown for a marker is the value of the waveform at the specified
horizontal time, which is set with the marker arrow keys. This is the default
mode. You can change the marker mode using the graphical interface. See the

Infiniium Oscilloscope Bottom of Display

To make it easy to see which controls affect each waveform, the oscilloscope
uses color consistently throughout the graphical interface. These colors match
the ones used on the front-panel knobs. For example, the color of the waveform
for channel 1 matches the color of the knobs for that channel. If channel 1 is
the trigger signal, all of the trigger configuration items, including the trigger
level reference icon (at the right side of the waveform display area), will match
that color. The buttons associated with that channel, vertical scaling and offset
settings, ground reference indicator, and measurements done on that channel
also have the same color.

All changes made to the front-panel settings are reflected in the graphical user
interface, and changes made using the graphical interface are reflected in the
front panel where applicable. Use whichever interface is easiest for you in a

3-24

Using the Oscilloscope

Graphical User Interface

particular measurement situation. For example, it might be easiest to set a
coarse vertical scale using the knobs, then fine-tune the setting using the
graphical user interface.

The graphical interface is arranged so that the most common functions affecting
the waveform display are located around the edge of the waveform viewing area.
These include the measurement toolbar, horizontal and trigger toolbar, and
vertical toolbar.

Measurement Toolbar

The measurement toolbar contains icons representing the most commonly used
automatic measurements built into the oscilloscope.

Drag and Drop Measurements By dragging one of the measurement
icons to a waveform in the waveform display area, you can make that
measurement on the waveform. As you drag a measurement icon around
the screen, the icon outline changes color to match the color of the closest
waveform. This makes it easy to see which waveform will be measured
when you drop the icon. For those measurements that are done on
waveform features, the measurement is made at the feature closest to the
location where you dropped the icon. For example, you might want to
measure the rise time of the fifth rising edge; dropping the rise time
measurement icon at that edge will cause the measurement to be made on
that edge.

You can also make a measurement by simply clicking the icon on the
measurement toolbar, then selecting the source to be measured in the dialog
box that appears. When you start a measurement this way, any measurements
on waveform-specific features will measure the feature closest to the horizontal
reference indicator.

Each waveform can have multiple simultaneous measurements and the
measurements can all be of the same type, if desired. For example, you can
have 3 pulse width measurements on different parts of the same waveform.

Geometric Measurement Indicators For each measurement currently
running, a geometric indicator at the measurement location on the
waveform corresponds to an identical indicator in the measurement results
readout. This makes it easy for you to verify that the readout shows results
for the correct waveform and the correct feature on that waveform. See
figure 3-38 for an example.

Tool Tips To find out what a particular measurement tool does, move the
mouse pointer over it for a moment. A small popup will appear that
describes the measurement.

Other Measurement Features There are more measurements available
than will fit on a single toolbar. Click the More (1 of 2) or More (2 of 2)
icons to see other measurements. Clicking Clear All will remove all selected
measurements from the waveform display area.

Tab Display Area

The tab display area is located beneath the waveform viewing area.

Tab Display Area

The display area shows information and statistics for the particular tab that is
selected. The type of markers that are shown in the waveform viewing area
depend on the tab that you have selected. The selected tab has an orange
border to reflect the type of markers being displayed. For example, when the
Histogram tab is selected, the markers are histogram markers and are used to
define the histogram window.

Waveform Display Area

The waveform display area shows the waveforms, and optionally, the results of
your measurements. Several display options, including a grid, are available and
can be configured using the graphical interface.

Waveform Manipulation When the graphical interface is enabled, two
features are available that can simplify your work with waveforms:

• Direct Manipulation—you can use the mouse to click and drag waveforms to

new vertical positions, which changes the vertical offset, or to new horizontal
positions, which changes the horizontal position or delay value.

• Zoom—you can click and drag a rectangular area on the display, then click

inside it to zoom on that section of the waveforms. The oscilloscope does
this in one of two ways. If acquisition is stopped, the magnification is done
by the oscilloscope software. If acquisition is running, the oscilloscope
automatically adjusts the vertical scaling and offset and the horizontal sweep
speed and position to present the zoomed section of the waveforms.

3-26

Using the Oscilloscope

Graphical User Interface

See “To zoom on a section of the waveform” on page 3-50.

Avoid Overdriving Vertical Input Amplifiers

When zooming on a waveform with the oscilloscope running, be careful to keep the
signal within the screen vertically to avoid overdriving the vertical input amplifiers.
Overdriving causes waveform distortion and erroneous measurement results.

Ground Reference Indicators A small symbol is shown at the right side
of the waveform display area for each waveform that is on, including
channels, waveform memories, and functions. This symbol represents the
ground reference point for each channel; it moves when you change the
vertical offset. You can also drag this symbol up and down using the mouse
or touch screen; doing so automatically changes the vertical offset for that
waveform.

Menu Control and Menus

The display looks like figure 3-16 and figure 3-17, including a menu bar,
measurement toolbar (if enabled), and graphical controls for vertical,
horizontal, trigger, and acquisition.

You can use the menu bar for most oscilloscope configuration functions.
Context-sensitive menus, which pop up to provide a selection of commands
within particular regions of the user interface, are available in the following
regions:

• Memory bar

• Waveform display area

•Measurement toolbar

• Horizontal and acquisition controls

You display a context-sensitive menu by clicking the right mouse button with
the pointer in one of these regions. For more information on context-sensitive
menus, see “To select a command from a context-sensitive menu” on page 3-34.

Vertical Settings and Controls The top of the waveform display area
includes the vertical settings and controls. All channels are shown with the
corresponding vertical scaling settings in volts per division. Each has a
checkbox allowing you to turn that channel on or off, and a set of controls
allowing you to change the vertical scaling. Clicking directly on the vertical
scaling value displays a pop-up numeric keypad allowing you to set a precise
vertical scale.

Horizontal and Trigger Toolbar

At the bottom of the waveform display area is the horizontal and trigger
toolbar. This includes the run/stop controls, the horizontal controls, and
the trigger controls.

Run/Stop Controls See figure 3-24. At the left side of the bar are four
icons:

• The leftmost is a blue-green octagon. Clicking on this starts an acquisition.

(Same as pressing the Run key on the front panel.)

• The next control is a red octagon. Clicking on this stops acquisition. (Same

as pressing the Stop key on the front panel.)

• The next control is a small windshield wiper. Clicking on this clears acquired

waveform data from the display. (Same as pressing the Clear Display key on
the front panel.)

• The next control is a printer. Clicking prints the screen to the default printer.

• The rightmost control is the waveform brightness control.

Horizontal settings and controls The middle of the bar contains the
horizontal settings and controls. Leftmost is a button, labeled with an “H.”
Clicking on this will display the horizontal setup dialog box.

Next is the current sweep speed. Clicking on this displays a pop-up numeric
keypad so you can set a particular sweep speed. Or, you can click on the two
icons to the right of the sweep speed setting to cycle through the preset speeds.
The left-hand icon shrinks the waveform, which decreases the sweep speed and
increases the time per division. The right-hand icon stretches the waveform,
which increases the sweep speed and decreases the time per division.

Next is the horizontal position (delay) setting. Clicking on this displays a pop­up numeric keypad that allows you to set a particular position. Or, you can use
the three icons to the right. The left arrow moves the waveform to the left, the
center “0” resets the delay to zero, and the right arrow moves the waveform to
the right.

Across the toolbar are three vertical arrows. These are the left, center, and
right horizontal reference indicators. Clicking on one of these arrows moves
the horizontal position to the respective horizontal reference position on the
display—left, center, or right. Assuming the horizontal position is at zero:

• Left means the information on the display is all post-trigger.

• Center means the information to the left of center is pretrigger; to the right

is post-trigger.

• Right means the information on the display is pretrigger.

3-28

Using the Oscilloscope

Graphical User Interface

The horizontal position value represents the time relative to the trigger at the
respective horizontal reference. When you change the horizontal sweep speed,
the waveforms expand and contract about this reference position.

Trigger settings and controls The right side of the bar contains the
trigger settings and controls. These will vary depending on the current
trigger configuration, which can be set using the front panel and the
graphical interface. Advanced trigger configuration items are available only
through the graphical interface. You can click on the button labeled with
a “T” to bring up the trigger setup dialog box.

When the scope is set for edge trigger on a particular channel, the trigger level
setting is shown. You can click on it to display a pop-up numeric keypad that
allows you to set a particular trigger level. You can also click on the up and
down arrows to the right of the setting to increase or decrease the trigger level,
respectively. You can also click on the trigger reference indicator at the right
side of the display and drag it up or down to change the trigger level.

To zoom on a section of the waveform

1 Click and hold the left mouse button or touch screen stylus in a blank

space within the waveform display area, then drag the pointer to draw
a rectangle around the areas of interest on the waveform(s) then
release.

2 Click once anywhere inside the rectangle drawn in step 1.

How the zoom takes place depends on whether acquisition is running or
stopped. If running, the oscilloscope adjusts vertical scale, vertical offset, sweep
speed, and horizontal position as necessary to best rescale the area you defined
in step 1. If stopped, the oscilloscope does a software magnification of the
waveform.

In either case, a small dialog box appears in the corner of the screen, with an
“Undo” button; by clicking this button, you will undo the zoom and return the
oscilloscope to its previous settings.

Avoid Overdriving the Vertical Input Amplifiers

When the oscilloscope is running, the input waveform can overdrive the vertical
input amplifiers if you expand the vertical excessively. The result is distortion of
the waveform. Ensure that you select a region that will keep all of the waveform
on the screen vertically.

To make a measurement on a waveform

To make a measurement on a waveform

• Click and hold the mouse button or touch screen stylus on a
measurement icon, then drag the icon to the waveform event you want
to measure then release.

or

• Click on a measurement icon, then specify which source you want to
measure in the dialog box that is displayed.

For measurements on waveform features, such as those that involve waveform
edges, if you click the measurement icon and specify a source, the measurement
defaults to using the feature closest to the horizontal reference point. When
you make the measurement using drag-and-drop, the measurement uses the
waveform feature closest to the point where you drop the icon.

Only the most commonly used measurements are available on the toolbar.
Others are available by selecting them from the Measure menu. A few
specialized measurements are available only through the GPIB programming
command set to the oscilloscope. See the Programmer’s Reference.

When you drag and drop a measurement icon on a waveform, notice that the
icon outline changes color to match the color of each waveform it touches. This
enables you to easily see which waveform will be measured when you release.
Also, the measurement results are also displayed in color to make it easy to see
which waveform source is being measured.

For edge-sensitive measurements, when you drop the measurement icon on a
waveform, a geometric icon appears in the waveform marker color. This icon
shows exactly where the measurement is being made. The icon is also displayed
next to the measurement results readout to associate the readout with the
waveform and feature being measured. See figure 3-38. This feature helps you
distinguish measurement results from each other when you make multiple
measurements on the same waveform, but at different waveform features. For
example, a series of rise time measurements on several different edges of the
same waveform all have unique geometric icons to show each measurement’s
location.
