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

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

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.

XY Waveform Triggering. The XY waveform is triggered
so you can synchronize periodic input signals to the XY
waveform. This feature is useful when only one part of
the period contains valid information that you want to
see in the XY format. Set the time base and trigger
location to acquire just that part of the period.
When you want to see the complete period of the signals
regardless of the time base setting, set the trigger source
to an unused channel and the trigger mode to Auto.

Configuring Your Oscilloscope Ethernet Settings
Before using the e*Scope feature, you must set your
oscilloscope Ethernet network settings. The TDS3000B
Series Digital Phosphor Oscilloscope User Manual,
Appendix G, Ethernet Setup, describes how to enter the
Ethernet network parameters for your oscilloscope.
Accessing e*Scope
After your instrument is set up with the correct ethernet
settings, you are ready to access that instrument over the
Internet. To access you instrument’s e*Scope server, do
the following steps:
1 On a PC or work station, open a network browser
program.
2 In the Location or Address field (where you normally
enter a URL), type in the IP address of the
TDS3000B instrument to which you want to connect.
For example, 188.121.212.107. Do not precede the IP
address with any characters. Then press the Return
key.
3 The browser program loads the instrument’s e*Scope
Web-based Remote Control home page, which is an
image of the screen contents when your browser
accessed the instrument.
e*Scope Web-based Remote Control
e*Scope introduces the next generation of oscilloscope
functionality. W ith e*Scope you can access any Internetconnected TDS3000B Series oscilloscope from a
browser on your work station, PC, or laptop computer.
No matter where you are, your TDS3000B is as close as
the nearest browser!
There are two levels to e*Scope: basic and advanced.
The basic level, which is hosted on the oscilloscope, lets
you view a screen image of the current acquisition, save
or load waveform and setup files, and remotely control
the oscilloscope using the oscilloscope programming
commands.
The advanced level, which is hosted on your system,
provides a graphical user interface to remotely control
the oscilloscope. To obtain the advanced level software,
go to the Tektronix TDS3000B website and download
the web-based remote control software.
NOTE. You can also use e*Scope on TDS3000
Series oscilloscopes that are equipped with a
TDS3EM Ethernet communication module and
are running firmware version 3 or above.

Automatic Measurements
Measurement
Definition
Amplitude Measured over the entire waveform.
Amplitude = High (100%) – Low (0%)
Burst
Width
The duration of a burst. Measured over the entire
waveform.
Cycle
Mean
The arithmetic mean over the first cycle in the
waveform.
Cycle
RMS
The true Root Mean Square voltage over the first
cycle in the waveform.
Delay The time between the Mid Reference crossings of
two different waveforms.
Fall Time Time that the falling edge of the first pulse in the
waveform takes to fall from 90% to 10% of its
amplitude.
Frequency Reciprocal of the period of the first cycle in the
waveform. Measured in Hertz (Hz).
High The value used as 100%. Calculated using either the
min/max or the histogram method. Measured over
the entire waveform.
Low The value used as 0%. Calculated using either the
min/max or the histogram method. Measured over
the entire waveform.
The menu at the top of the page provides the following
functions:
H Home displays the oscilloscope screen.
H Applications takes you to the application URL
specified in the Configure tab. The default URL is the
application notes site at www.tektronix.com.
H Configure lets you specify URLs for the advanced
Web-based Control HTML pages (Control),
application notes (Applications), and help files
(Help). The default values are for the Tektronix web
site. However, you can host any of these on your
local Intranet for faster access and better system
security.
H Data lets you upload or download waveform data
files and oscilloscope settings, as well as remotely
control the oscilloscope using oscilloscope
programing commands.
H Status displays the version screen, which shows the
firmware version and lists installed application
modules.
H Control displays the advanced Web-based Control
page that lets you remotely control the oscilloscope.
