Cleaning
Inspect the oscilloscope and probes as often as operating conditions require. To clean the exterior surface, perform the following
steps:
1. Remove loose dust on the outside of the oscilloscope and probes with a lint-free cloth. Use care to avoid scratching the clear
glass display filter.
2. Use a soft cloth dampened with water to clean the oscilloscope. Use an aqueous solution of 75% isopropyl alcohol for
more efficient cleaning.
CAUTION. To avoid damage to the surface of the oscilloscope or probes, do not use an y abrasive or chemical cleaning agents.

Connecting Probes
The oscilloscope supports probes with the following:
1. Tektronix Versatile Probe Interface
(TekVPI)
These probes support t wo-wa y
communication with the oscilloscope
through on-screen menus and remotely
through programmable support. The
remote control is useful in applications like
ATE where you want the system to preset
probe parameters.
2. TPA-BNC Adapter
The TPA-BNC Adapter allows you to use
TEKPROBE II probe capabilities, such as
providing probe power, and p assing scaling
and unit information to the oscilloscope.
Installation
DPO3000 Series Oscilloscopes User Manual 13
Installation
3. Plain BNC Interfaces
Some of these use TEKPROBE capabilities
to pass the waveform signal and scaling
to the oscilloscope. Some only pass the
signal and there is no other communication.
For more information on the many probes available for use with DPO3000 series oscilloscopes, refer to www.tektronix.com.

Securing the Oscilloscope
1. Use a standard laptop computer style
security lock to secure your oscilloscope
to your location.

Powering On the Oscilloscope
Ground the Oscilloscope and Yourself
Before pushing the power switch, connect the oscilloscope to an electrically neutral reference point, s uch as earth ground. Do this
by plugging the three-pronged power cord into an outlet grounded to earth ground.
Grounding the oscilloscope is necessary for safety and to take accurate measurements. The oscilloscope needs to share the
same ground as any circuits that you are testing.
If you are working with static sensitive
components, ground yourself. Static electricity
that builds up on your body can da mage
static-sensitive components. Wearing a
grounding strap safely sends static charges on
your body to earth ground.

Functional Check
Perform this quick functional check to verify that your oscilloscope is operating correctly.
1. Connect the oscilloscope power cable as
described in Powering On the Oscilloscope.
(See page 16.)
2. Power on the oscilloscope.
Installation
DPO3000 Series Oscilloscopes User Manual 19

3. Connect the P6139A probe tip and
reference lead to the PROBE COMP
connectors on the oscilloscope.
4. Push Default Setup.
20 DPO3000 Series Oscilloscopes User Ma nual
5. Push Autoset. The screen should now
display a square wave, approximately
2.5Vat1kHz.
NOTE. For best performance, it is
recommended that you set the Vertical scale
to 500 mV.
If the signal appears but is misshapen,
perform the procedures for compensating
theprobe.(Seepage22,Compensating a
Passive Voltage Probe.)
If no signal appears, rerun the procedure.
If this does not remedy the situation , have
the instrument serviced by qualified service
personnel.

Whenever you attach a passive voltage probe for the first time to any input channel, compensate the probe to match it to
the corresponding oscilloscope input channel.
To properly compensate your passive probe:
1. Follow the steps for the functional
check. (See page 19, Functional
Check.)
2. Check th e shape of the displayed
waveform to determine if your probe
is properly compensated.

Repeat as needed.

Application Module Free Trial
A 30-day fre e trial is available for all application modules not installed in your oscilloscope. The trial period begins when you power
on the oscilloscope fo r the first time.
After 30 days, you must purchase the module if you want to continue using the application. To see the date when your free trial
period expires, push the front panel Utility button, push the lower-bezel Utility Page button, use multipurpose knob a to select
Config, and push the lower-bezel About button.

Installing an Application Module
CAUTION. To avoid damage to the oscilloscope or application module, observe ESD (electrostatic discharge) precautions.
(See page 16, Powering On the Oscilloscope.)
Turn off the oscilloscope power while removing or ad ding an application module.
(See page 18, Powering Off the Oscilloscope.)
Optional application module packages extend the cap ability of your oscilloscope. You can install up to four application modules at
one time. Application modules go into the two slots with windows in the upper right corner of the front panel. Two additional slots
are directly behind the two that you can see. To use these slots, install the module with the label facing away from you.
Refer to the Tektronix 3000 Series Oscilloscopes Application Module Installation Instructions that came with your a pplication module
for instructions on installing and testing an application module.
NOTE. If you remove an application module, the features provided by the application module become unavailable. To restore the
features, turn off the oscilloscope power, reinstall the module and turn on the oscilloscope power.

Signal Path Compensation
Signal Path Compensation (SPC) corrects for DC inaccuracies caused by temperature variations and/or long-term drift. Run the
compensation whenever the ambient temperature has changed by more than 10 °C or once a week if you use vertical settings of
5 mV/division or less. Failure to do so may result in the instrument not meeting warranted performance levels at those volts/div
settings.
To compensate the signal path:
1. Warm up the oscilloscope for at least
20 minutes. Remove all input signals ( probe s
and cables) from channel inputs. Input signals
with AC compo nents adversely affect SPC.

Connecting Your Oscilloscope to a Computer
You may want to document your work for future reference. Instead of saving screen images and waveform da ta to a USB flash
drive, and then generating a report later, you may want to send the image o r waveform data directly to a remote PC for analysis.
You may also want to control an oscilloscope at a remote location from your computer. (See page 203, Saving a Screen Image.)
(See page 204, Sa ving and Recalling Waveform Data.)
Two ways to connect your oscilloscope to a computer are through the VISA drivers and the e*Scope Web-enabled tools. Use
VISA to communicate with your oscilloscope from your computer through a software application. Use e*Scope to communicate
with your oscilloscope through a Web browser.
Using VISA
VISA lets you use your MS-Windows computer to acquire data from your oscilloscope for use in an analysis package that runs on
your PC, such as Microsoft Excel, National Instruments LabVIEW, or a program of your own creation. You can use a common
communications connection, such as USB, Ethernet, or GPIB, to connect the computer to the oscilloscope.
To set up VISA communications between your oscilloscope a nd a computer:
1. Load the VISA drivers on your computer.
You will find the drivers on the appropriate
CD that comes with your oscilloscope or
at the Tektronix software finder Web page
(www.tektronix.com/software).

2. Connect the oscilloscope to your computer
with the appropriate USB or Ethernet cable.
To communicate between the oscilloscope and
a GPIB system, connect the oscilloscope to
the TEK-USB-488 GPIB-to-USB Adapter with
a USB cable. Then connect the adapter to
your GPIB system with a GPIB cable. Cycle
the power on the oscilloscope.

Quick Tips
The CD that is shipped with your oscilloscope includes a variety of Windows-based software tools designed to ensure efficient
connectivity between your oscilloscope and your computer. There are toolbars that speed connectivity with Microsoft Excel and
Word. There is also a standalone acquisition program called the OpenChoice Desktop.
The rear-panel USB 2.0 device port is the correct USB port for computer connectivity. Use the rear- and front-panel USB 2.0
host ports to connect your oscilloscope to USB flash drives and printers.

Connecting a USB Keyboard to Your Oscilloscope
You can connect a US-style USB keyboard to a USB Host port on the rea r or front panel of the oscilloscope. The oscilloscope will

You can use the keyboard to quickly create names or labels. You can bring up the Label menu through the lower-bezel label button
of the Channel or Bus menus. Use the arrow keys on the keyboard to move the insertion point, and then type in a name or label.
Labeling channels and buses makes the information on the screen easier to identify.
