Safety Summary

To avoid potential hazards, use this product only as
specified in the TDS3000B Series Digital Phosphor

Oscilloscope User Manual which is located on the
TDS3000B Series Digital Phosphor Oscilloscope
Manuals and Application Notes CD. While using this

product, you may need to access other parts of the
system.

Read the General Safety Summary in the user manual
and in other system manuals for warnings and cautions
related to operating the system.

Preventing Electrostatic Damage

CAUTION. Electrostatic discharge (ESD) can

damage components in the oscilloscope and its
accessories. To prevent ESD, observe these
precautions when directed to do so.

Use a Ground Strap. W ear a grounded antistatic wrist strap

to discharge the static voltage from your body while
installing or removing sensitive components.

information about using this product.

generating or holding a static charge in the work area
where you install or remove sensitive components.
Avoid handling sensitive components in areas that have a
floor or benchtop surface capable of generating a static
charge.

Handle Components Carefully. Do not slide sensitive

components over any surface. Do not touch exposed
connector pins. Handle sensitive components as little as
possible.

Transport and Store Carefully . Transport and store sensitive

components in a static-protected bag or container.

Manual Storage

The oscilloscope front cover has a convenient place to
store this manual.

3. Connect the oscilloscope probe
to channel 1. Attach the probe
tip and reference lead to the

PROBE COMP connectors.

4. Push the AUTOSET button.

You should see a square wave
in the display (approximately
5 V at 1 kHz).

Probe Compensation

5. Check the shape of the dis­played waveform.

6. Adjust your probe if necessary
to achieve correct compensa­tion.

TDS3000B Initial Setup

The following procedures describe how to quickly verify
that the oscilloscope is powering up and functioning
correctly, compensate passive probes using the built-in
compensation signal, and run the signal path compensa­tion (SPC) routine for maximum signal accuracy.

H You should perform all initial setup procedures the

first time you use the oscilloscope.

H You should perform the probe compensation

procedure whenever you attach a passive probe for
the first time to any input channel.

H You should run the signal path compensation routine

whenever the ambient temperature changes by 10_ C
or more.

Adjusting Time and Date

To set your oscilloscope to the current date and time, do
the following steps:

1 Push the UTILITY button.
2 Push the System menu button to select Config.
3 Push the Set Date & Time menu button.
4 Use the side menu buttons and general purpose knob

to adjust the date and time values.

5 Push the OK Enter Date/Time menu button to set

the instrument date and time.

User Manual

The TDS3000B Series DPO Oscilloscope Manuals and
Application Notes CD contains the TDS3000B Series
Digital Phosphor Oscilloscope User Manual, translated

into all supported languages. The user manual contains
complete information on how to operate your
TDS3000B Series oscilloscope.

The CD also contains manuals for all TDS3000B Series
accessories, application notes, oscilloscope and probe
fundamentals, and software to install the Adobe Acrobat
Reader, which is required to view the online documents.

The signal path compensation (SPC) routine optimizes
the oscilloscope signal path for maximum measurement
accuracy. You can run the routine anytime but you
should always run the routine if the ambient temperature
changes by 10_ C or more.

To compensate the signal path, do the following steps:

1 Disconnect all probes or cables.
2 Push the UTILITY button.
3 Push the System screen button to select Cal.
4 Push the Signal Path screen button.
5 Push OK Compensate Signal Path.

Setting the User Interface Language

To set the user interface language, do the following
steps:

1 Push the UTILITY button.
2 Push the System screen button to select Config.
3 Push a side menu button to select a language.

To use a QuickMenu, do these steps

1 Push the QUICKMENU button on the front panel.
2 Push the screen button that corresponds to the control

you need to set. Push the screen button repeatedly to
choose one of the settings. The small arrow icon
indicates that there are additional settings available
that are not shown.

You can use most of the front-panel controls at the same
time you are using a QuickMenu. For example, if you
push a channel button to select a different channel, the
QuickMenu changes to show information about that
channel.

You can still use the regular menus. For example, if you
push the MEASURE button, you can set up and take
automatic waveform measurements in the usual way. If
you return to the QuickMenu, the measurement is still
displayed on the screen.

You may have optional application modules installed
that also have QuickMenu displays. To select the Quick­Menu you want to use, push the MENU screen button.
This menu item is shown only if application modules
that contain a QuickMenu are installed.

QuickMenus

The QuickMenu feature simplifies the use of the oscillo­scope. When you push the QUICKMENU button, a set
of frequently used menu functions show on the display.

Scope is one type of QuickMenu that you can use to
control the basic oscilloscope functions. You can per­form many tasks without using the regular menu system.
