Oscilloscopes

The Keysight Infiniium Oscilloscope Model 8000 Series at a Glance

Ease of use with high performance

The Keysight Technologies Infiniium oscilloscopes

combine unprecedented ease-of-use with high-

performancedigitizingoscilloscopefunctionalityto

simplify your design and analysis measurement

tasks.

•Traditional oscilloscope front-panel interface

provides direct access to the controls needed for

most troubleshooting tasks.

•Touchscreen graphical user interface withmenus,

windows, dialogs, and toolbars provides easy

access to dozens of configuration and analysis

tools, ensuring you can set up and make the

most complex measurements.

•Keysight DSO8064A offers 4 channels, 4 GSa/s

sampling rate in 2-channel mode, 2 GSa/s

sampling rate in 4-channel mode, 600 MHz

bandwidth. The MSO8064A also includes 16

digital channels.

•Keysight DSO8104A offers 4 channels, 4 GSa/s

sampling rate in 2-channel mode, 2 GSa/s

sampling rate in 4-channel mode, 1 GHz

bandwidth. The MSO8104A also includes 16

digital channels.

Display shows waveforms and graphical user

interface

•Graphical interface allows direct interaction with

waveforms, including drag-and-drop positioning

and instant waveform zoom

•Touchscreen display allows oscilloscope

operation without an external pointing device

•Waveforms displayed in color, making correlation

easy

•Current configuration parameters displayed near

the waveform display and are color-coded to

make identification easy

•Graphical interface menus and toolbars simplify

complex measurement setups

Horizontal controls set sweep speed and position

•Main sweep speeds from 200 ps/div to 20 s/div

•Delayed sweep speeds from 1 ps/div to main time

base setting

•Intensified waveforms on main sweep window

make it easy to see what will appear in delayed

sweep window

Acquisition and general controls start and stop

the oscilloscope and do basic setup

•Run and stop controls for continuous or single-

shot acquisitions

•Clear display before one or more acquisitions

•Default setup and Autoscale set initial

configuration

Hard disk drive and USB port for saving and

restoring setups and measurement results

•Store measurement displays for inclusion in

reports and test setup guides

•Store oscilloscope setups to repeat tests another

time

•Hard disk stores oscilloscope operating system

Trigger setup controls set mode and basic

parameters

•Select Edge, Glitch, or Advanced Modes

•Choose input source and slope

•Set coupling for trigger

•Use graphical user interface to simplify

configuration of pattern, state, delay, violation,

and video triggers

•Use auxiliary trigger to increase triggering

flexibility

Vertical controls set input coupling, impedance,

attenuation, and position

•AC or DC input coupling

•1 MΩor 50 Ωinput impedance

•Input attenuation adjustablefrom 2 mV/div to 1 V/

div (plus 2 V/div in 1 MΩ)

•Color-coded knobs make it easy to find the

controls that affect each waveform

Marker and quick measurements help measure

waveform parameters

•Waveform markers A and B to check voltage and

Δ-time at any point on the displayed waveform

•Quick Meas executes up to four predefined

measurements instantly

Service Policy

The service policy of this oscilloscope requires

replacing defective assemblies. Some assemblies

can be replaced on an exchange basis. Items such

as the vertical attenuators, which are subject to

wear and tear based on frequency of use, are a

maintenance item that may need occasional

replacement.

oscilloscopes. It is divided into eight chapters.

Chapter 1, “General Information,” provides general information and specifications.

Chapter 2, “Preparing for Use,” shows you how to prepare the oscilloscope for use.

Chapter 3, “Testing Performance,” gives performance tests.

Chapter 4, “Calibrating and Adjusting,” covers calibration and adjustment procedures,

how to do them, and how often they need to be done.

Chapter 5, “Troubleshooting,” provides troubleshooting information.

Chapter 6, “Replacing Assemblies,” gives the procedures and techniques for replacing

assemblies and other parts.

Chapter 7, “Replaceable Parts,” includes a list of exchange assemblies and other

replaceable parts, part ordering information, and shipping information.

Chapter 8, “Theory of Operation,” briefly covers the internal operation of the oscilloscope.

At the back of the book you will find safety notices.
