Lab Guide—At a Glance
This advanced oscilloscope training guide and tutorial is intended to be used with
Keysight Technologies InfiniiVision 4000 X-Series oscilloscopes (DSO and MSO
models) that are licensed with the Oscilloscope Education Training Kit (DSOXEDK).
When licensed with this training kit, 4000 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, or use the all
new touchscreen interface to select a signal directly.
4Press the Output softkey to enable the training signal output on the Demo
terminal(s). The signal will also begin output when double pressed in the menu.

4000 X-Series Oscilloscopes Advanced Training Guide 7
If you not familiar with the Keysight InfiniiVision 4000 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 13.
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.
•Pressthe[Single] key to make a single acquisition and stop the acquisition
process.
Waveform Controls
•The[Analyze] key sets trigger levels, measurement threshold levels, video
trigger auto setup and display, or the mask testing application options.
•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.
•Pressthe[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.
