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.

Getting Started 1

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.

1Getting Started

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.

Getting Started 1

4000 X-Series Oscilloscopes Advanced Training Guide 9

•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.
