Safety Notices
CAUTION
A CAUTION notice denotes a haz-
ard. It calls attention to an operat-
ing procedure, practice, or the like
that, if not correctly performed or
adhered to, could result in damage
to the product or loss of important
data. Do not proceed beyond a
CAUTION notice until the indicated
conditions are fully understood and
met.
WARNING
A WARNING notice denotes a
hazard. It calls attention to an

the like that, if not correctly per-
formed or adhered to, could result
in personal injury or death. Do not
proceed beyond a WARNING
notice until the indicated condi-
tions are fully understood and met.

Lab Guide—At a Glance
This advanced oscilloscope training guide and tutorial is intended to be
used with Agilent Technologies InfiniiVision 2000 X- Series oscilloscopes
(DSO and MSO models) that are licensed with the Oscilloscope Education
Training Kit (DSOXEDK). When licensed with this training kit,
2000 X- Series oscilloscopes are able to generate a broad range of built- in
training signals.
The built- in training signals can be probed by simply connecting a
standard 10:1 passive probe between channel- 1’s input BNC and the front
panel terminal labeled “Demo 1”, and another probe between channel- 2’s
input BNC and the terminal labeled “Demo 2” as shown on the next page.
To turn on specific training signals for each of the labs documented in this
training guide, simply:
1Press the scope’s front panel [Help] key.
2Press the Training Signals sofkey.
3Turn the Entry knob to select the appropriate training signal.
4Press the Output softkey to enable the training signal output on the
Demo terminal(s).

6 2000 X-Series Oscilloscopes Advanced Training Guide
1Getting Started
If you not familiar with the Agilent InfiniiVision 2000 X- Series
oscilloscope, first look over the main sections of the front panel as
illustrated on the following pages, and then begin with Chapter 2,
“Oscilloscope Familiarization Labs,” starting on page 11.
Once you have become familiar with using the basic functions of the
oscilloscope, you can then skip to particular labs of interest. Each
hands- on lab can be considered as a standalone lab exercise because each
begins with a default setup. In other words, successive labs do not build
on the previous lab. They can be completed in any order of preference.
Front Panel Overview
For instant help on any topic, press and hold any key, softkey, or knob.

Run Control
When the oscilloscope is turned on, or if [Auto Scale] is pressed, the
acquisition will be set to [Run]. At any time you may [Stop] the acquisition
process to examine a signal in detail or to save it.
•The [Default Setup] key on the front panel sets the oscilloscope to the
default configuration.
Because the oscilloscope may have been used in a variety of
applications by a variety of people, it is a good measurement procedure
to put the oscilloscope in a known starting mode (Default Setup). This
makes it easy to duplicate measurements because no special conditions
are set.
•The [Auto Scale] key on the front panel automatically configures the
oscilloscope by analyzing all active channels, turning them on and
setting the timebase, V/div, and trigger conditions for an initial display.
•Press the [Single] key to make a single acquisition and stop the
acquisition process.
Waveform Controls
•The [Acquire] key on the front panel lets you set the oscilloscope data
acquisition modes.
•The [Display] key on the front panel lets you set the waveform
persistence options and the grid type and grid intensity.

•The [Intensity] key and the Entry knob lets you set the desired
signal brightness.
Horizontal Controls
aTurn the large knob in the Horizontal control section clockwise and
counter- clockwise to control the time/div setting of the horizontal
axis.
Observe the changes in the displayed signal. The current timebase
setting is displayed at the top of the display on the status line.
bTurn the small knob in the horizontal control section to move the
trigger point (solid orange triangle) from the reference point (hollow
orange triangle).
cPress the [Horiz] key to display the Horizontal menu. Note the various
Time Modes of Normal, Roll, and XY. Also notice the Zoom mode
softkey.
dPress the (zoom) key to quickly turn on the zoom mode. This
split- screen mode shows the big picture on top and an expanded
view on the bottom. Turn the large timebase knob counter- clockwise
to make the window on top larger.

Vertical Controls
•Turn the large knobs in the Vertical section to control the V/div setting
for each analog channel. The V/div setting is displayed in the upper left
hand corner of the status line at the top of the display.
Color coding matches analog channel inputs, vertical control knobs, and
waveform colors.
•Press the [1] key to display the channel 1 menu. Press again to turn the
channel on and off.
•Turn the small knobs to control the vertical offset position of the
waveform, moving the ground level up or down.
Trigger Controls
•Turn the Trigger Level knob to move the trigger level up and down. The
trigger level is displayed while it is adjusted. If the trigger level is above
or below the signal and the oscilloscope is in Auto trigger mode, the
oscilloscope will force a trigger and display an acquisition (waveform).
Auto trigger mode is useful when unsure of the exact waveform because
forced acquisitions are displayed, making it easy to better configure the
oscilloscope’s settings and trigger level.
•Press the [Mode/Coupling] key in the Trigger controls section to view the
Trigger Mode and Coupling Menu selections and to set trigger holdoff.

1Getting Started
•Press and hold the Mode softkey to read the built- in help about the
Auto and Normal trigger modes.
Tools Controls
•Press the [Utility] key to access the I/O ports, file explorer, options,
service information, and the “Quick Action” key function settings.
•Press the [Quick Action] key to perform one of the quick action functions
that can be mapped to this key.
•Press the [Analyze] key to set trigger levels, measurement threshold
levels, video trigger auto setup and display, or the mask testing
application options.
