•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 manufactured after the date this manual was released may be different
from those described in this manual. The release date of this manual is shown on the
title page. This manual will be revised as needed (when significant changes occur).
If you have an oscilloscope that was manufactured after the release of this manual,
please check the Keysight Technologies website at www.keysight.com to see whether a
newer version of this manual is available. You can perform a search for your
oscilloscope’s model number, go to its product page, and select Library.
Year of Manufacture
You can determine the year the oscilloscope was manufactured by examining the serial
number label that is affixed to the rear panel of the oscilloscope. The serial number is
composed of two parts. The first part contains two letters and two numbers that signify
the oscilloscope’s county of origin and year date code. A year date code of “05” indicates
that the oscilloscope was manufactured in 2005. The second part of the serial number
contains a rolling number that is different for each oscilloscope.

Chapter 1: General Information
Environmental Conditions
17
Environmental Conditions
Overvoltage Category
This product is intended to be powered by MAINS that comply to Overvoltage Category
II, which is typical of cord- and- plug connected equipment.
Pollution Degree
The 80000 Series Oscilloscope may be operated in environments of Pollution Degree 2
(or Pollution Degree 1).
Pollution Degree Definitions
Pollution Degree 1: No pollution or only dry, non- conductive pollution occurs. The
pollution has no influence. Example: A clean room or climate controlled office
environment.
Pollution Degree 2. Normally only dry non- conductive pollution occurs. Occasionally a
temporary conductivity caused by condensation may occur. Example: General indoor
environment.
Pollution Degree 3: Conductive pollution occurs, or dry, non- conductive pollution occurs
which becomes conductive due to condensation which is expected. Example: Sheltered
outdoor environment.
Measurement Category
Measurement Category
The 80000 Series oscilloscope is intended to be used for measurements in Measurement
Category I.
Measurement Category Definitions
Measurement category I is for measurements performed on circuits not directly connected
to MAINS. Examples are measurements on circuits not derived from MAINS, and specially
protected (internal) MAINS derived circuits. In the latter case, transient stresses are
variable; for that reason, the transient withstand capability of the equipment is made
known to the user.
Measurement category II is for measurements performed on circuits directly connected
to the low voltage installation. Examples are measurements on household appliances,
portable tools and similar equipment.
Measurement category III is for measurements performed in the building installation.
Examples are measurements on distribution boards, circuit- breakers, wiring, including
cables, bus-bars, junction boxes, switches, socket- outlets in the fixed installation, and
equipment for industrial use and some other equipment, for example, stationary motors
with permanent connection to the fixed installation.
Measurement category IV is for measurements performed at the source of the low-
voltage installation. Examples are electricity meters and measurements on primary
overcurrent protection devices and ripple control units.
Transient Withstand Capability
The maximum transient withstand capability of this instrument is not specified. Do not
apply more than 5 volts rms at the oscilloscope’s vertical input BNC connectors.

Setting Up the Oscilloscope
This chapter shows you how to set up your Infiniium oscilloscope, connect
power and accessories, and verify general operation.
To inspect package contents
❏Inspect the shipping container for damage.
Keep a damaged shipping container or cushioning material until you have inspected
the contents of the shipment for completeness and have checked the oscilloscope
mechanically and electrically.
❏Verify that you received the following items in the Infiniium Oscilloscope packaging.
• Infiniium Oscilloscope
•Mouse
•Touchscreen Stylus
• (4) 10073C 10:1 10 MΩpassive probes
• Digital Probe Kit (MSO models only)
• Accessory Pouch
• Front Panel Cover
•Keyboard
• Power cord (See page 139)
• User’s Quick Start Guide
If anything is missing, contact your nearest Keysight Technologies Sales Office. If the
shipment was damaged, contact the carrier, then contact the nearest Keysight
Technologies Sales Office.
❏Inspect the oscilloscope.
• Contact your Keysight Technologies sales office if:
• mechanical damage or a defect is apparent
• the oscilloscope does not operate properly
• If the shipping container is damaged, or the cushioning materials show signs of stress,
notify the carrier and your Keysight Technologies Sales Office. Keep the shipping
materials for the carrier’s inspection. The Keysight Technologies Sales Office will
arrange for repair or replacement at Keysight’s option without waiting for claim
settlement.
