About This Manual
This manual covers the operation and maintenance of all instruments in the HDO4000 series. With the
introduction of later versionsof the 64-bit MAUI software, particularly version 8.3 and later, the graphical
user interface on some instruments looked very different from what was offered on earlier instruments
and included different touch screen capabilities.
In particular, HDO4000 non-"A" models may look somewhat different than what isshown in this manual
(HDO4000A is shown here).
Despite the difference in appearance, however, the functionality is the same unless otherwise stated.
Where there are differences or limitations in capabilities, these are explained in the text.
Documentation for using optionalpackages sold for Teledyne LeCroy instruments can be downloaded
from teledynelecroy.com/support/techlib. Our website maintains the most current product specifications
and should be checked for frequent updates.

HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual
Operating Environment
Temperature: 5 to 40° C.
Humidity: Maximum relative humidity 90 % for temperatures up to 31° C, decreasing linearly to 50%
relative humidity at 40° C.
Altitude: Up to 3,000 m at or below 30° C.
Cooling
The instrument relies on forced air cooling with internal fans and vents. Take care to avoid restricting the
airflow to any part. In a benchtop configuration, leave a minimum of 15 cm (6 inches) around the sides
between the instrument and the nearest object. The feet provide adequate bottom clearance. Follow
rackmount instructionsfor proper rack spacing.
Caution: Do not block the cooling vents.
The instrument also has internal fan control circuitry that regulates the fan speed based on the ambient
temperature. This is performed automatically after start-up.
Cleaning
Clean only the exterior of the instrument using a soft cloth moistened with water or an isopropylalcohol
solution. Do not use harsh chemicals or abrasive elements. Under no circumstances submerge the
instrument or allow moisture to penetrate it. Dry the instrument thoroughly before connecting a live
voltage source.
Caution: Unplug the power cord from the AC inlet before cleaning to avoid electric shock. Do not
attempt to clean internal parts. Refer all maintenance to qualified service personnel.

Safety
Power
AC Power
The instrument operates from a single-phase, 100-240 Vrms(± 10%) AC power source at 50/60 Hz (± 5%)
or a 100-120 Vrms (± 10%) AC power source at 400 Hz (± 5%). Manual voltage selection is not required
because the instrument automatically adapts to the line voltage.
Power Consumption
Maximum power consumption with all accessories installed (e.g., active probes, USB peripherals, digital
leadset) is 300 W (300 VA) for four-channel modelsand 250 W (250 VA) for two-channel models. Power
consumption in Standby mode is 4 W.
Ground
The AC inlet ground is connected directly to the frame of the instrument. For adequate protection again
electric shock, connect to a mating outlet with a safety ground contact.
Caution: Use only the power cord provided with your instrument. Interrupting the protective
conductor (inside or outside the case), or disconnecting the safety ground terminal, creates a
hazardous situation. Intentionalinterruption is prohibited.

Front Panel
Front panel controls duplicate functionality available
through the touch screen and are described here only
briefly.
Knobs on the front panel function one way if turned and
another if pushed like a button. The first label describes
the knob’s “turn” action, the second label its “push” action.
Actions performed from the front panel always apply to
the active trace.
Many buttons light to show the active traces and
functions.
Trigger Controls
Level knob changes the trigger threshold level (V). The
level is shown on the Trigger descriptor box. Pushing the
knob sets the trigger level to the 50% point of the input
signal.
READY indicator lights when the trigger is armed. TRIG'D
indicator is lit momentarily when a trigger occurs.
Setup opens/closes the Trigger Setup dialog.
Auto sweeps after a preset time, even if the trigger
conditions are not met.
Normal sweeps each time the trigger signal meets the
trigger conditions.
Single sets Single trigger mode. The first press readies
the oscilloscope to trigger. The second press arms and
triggers the oscilloscope once (single-shot acquisition)
when the input signal meets the trigger conditions.
Stop pauses acquisition. If you boot up the instrument with the trigger in Stop mode, a "No trace available"
message is shown. Press the Auto button to display a trace.
Horizontal Controls
The Delay knob changes the Trigger Delay value (S) when turned. Push the knob to return Delay to zero.
The Horizontal Adjust knob sets the Time/division (S) of the acquisition system when the trace source is
an input channel. The Time/div value is shown on the Timebase descriptor box. When using this control,
the instrument allocates memory as needed to maintain the highest sample rate possible for the timebase
setting. When the trace is a zoom, memory or math function, turn the knob to change the horizontal scale
of the trace, effectively "zooming" in or out. By default, values adjust in 1, 2, 5 step increments. Push the
knob to change to fine increments; push it again to return to stepped increments.

Oscilloscope Overview
Math, Zoom, and Mem(ory) Buttons
The Zoom button creates a quick zoom for each open channel trace. Touch the zoom trace descriptor
box to display the zoom controls.
The Math and Mem(ory) buttons open the corresponding setup dialogs.
If a Zoom, Math or Memory trace is active, the button illuminates to indicate that the Vertical and
Horizontal knobs will now control that trace.
Vertical Controls
Offset knob adjusts the zero level of the trace (making it appear to move up/down relative to the center
axis). The voltage value appears on the trace descriptor box. Push the knob to return Offset to zero.
Gain knob sets vertical scale (V/div). The voltage value appears on the trace descriptor box. By default,
values adjust in 1, 2, 5 step increments. Push the knob to change to fine increments; push it again to return
to stepped increments.
Channel (number) buttons turn on a channel that is off, or activate a channel that is already on. When the
channel is active, pushing its channel button turns it off. A lit button shows the active channel.
Dig button enables digital input through the Digital Leadset on instruments with the Mixed Signal option.
Cursor Controls
Cursors identify specific voltage and time values on a waveform. The white cursor markers help make
these points more visible. A readout of the values appears on the trace descriptor box. There are five
preset cursor types, each with a unique appearance on the display. These are described in more detail in
the Cursors section.
Type selects the cursor type. Continue pressing to cycle through all cursor until the desired type is found.
The type "Off" turns off the cursor display.
Cursor knob repositions the selected cursor when turned. Push it to select a different cursor to adjust.
Adjust and Intensity Controls
The front panel Adjust knob changes the value in active (highlighted) data entry fields that do not have
dedicated knobs. Pushing the Adjust knob toggles between coarse (large increment) or fine (small

Oscilloscope Overview
Signal Interfaces
The instrument offers a variety of interfaces for using probes or other devices to input analog or digital
signals. See the product page at teledynelecroy.com for a list of compatible devices.
Analog Inputs
A series of connectors arranged on the front of the instrument are used to input analog signals on
channels 1-4. EXT can be used to input an external trigger pulse. AUX IN on the back may also be used to
input analog signal.
HDO channel connectors use the ProBus interface. The ProBus interface contains a 6-pin power and
communication connection and a BNC signal connection to the probe. It includes sense rings for detecting
passive probes and accepts a BNC cable connected directly to it. ProBus offers 50 Ω and 1 MΩ input
impedance and control for a wide range of probes.
The channel interfaces power probes and completely integrate the probe with the channel. Upon
connection, the probe type is recognized and some setup information, such as input coupling and
attenuation, is performed automatically. This information is displayed on the Probe Dialog, behind the
Channel (Cx) dialog. System (probe plus instrument) gain settings are automatically calculated and
displayed based on the probe attenuation.
Probes
The oscilloscope is compatible with the included passive probes and most Teledyne LeCroy ProBus active
probes that are rated for the instrument’s bandwidth. Probe specifications and documentation are
available at teledynelecroy.com/probes.
Passive Probes
The passive probes supplied are matched to the input impedance of the instrument but may need further
compensation. Follow the directions in the probe instruction manual to compensate the frequency
response of the probes.
Active Probes
Most active probes match probe to oscilloscope response automatically using probe response data stored
in an on-board EEPROM. This ensures the best possible combined probe plusoscilloscope channel
frequency response without the need to perform any de-embedding procedure.
Be aware that many active probes require a minimum oscilloscope firmware version to be fully
operational. See the probe documentation.
11
HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual
Digital Leadset
The digital leadset provided with -MS model
oscilloscopes enables input of up-to-16 lines of
digital data. Lines can be organized into four
logical groups and renamed appropriately.
The digital leadset features two digital banks with
separate Threshold controls, making it possible to
simultaneously view data from different logic
families.
Connecting/Disconnecting the Leadset
The digital leadset connects to the Mixed Signal
interface on the front of the instrument.
To connect the leadset to the instrument, push the
connector into the Mixed Signal interface below
the front panel until you hear a click.
To remove the leadset, press and hold the buttons
on each side of the connector, then pull out to
release.
Grounding Leads
Each flying lead has a signal and a ground
connection. A variety of ground extenders and
flying ground leads are available for different probing needs.
To achieve optimal signal integrity, connect the ground at the tip of the flying lead for each input used in
your measurements. Use either the provided ground extenders or ground flying leads to make the ground
connection.

Oscilloscope Set Up
Oscilloscope Set Up
Powering On/Off
Press the Power button to turn on the instrument. The X-Stream application loads automatically
when you use the Power button.
Caution: Do not change the instrument’s Windows®Power Options setting from the default Never
to System Standby or System Hibernate. Doing so can cause the system to fail.
Caution: Do not power on or calibrate with a signal attached.
The safest way to power down the oscilloscope is to use the File > Shutdown menu option, which will
always execute a proper shut down process and preserve settings. Quickly pressing the power button
should also execute a proper shut down, but holding the Power button will execute a “hard” shut down (as
on a computer), which we do not recommend doing because it does not allow the Windows operating
system to close properly, and setup data may be lost. Never power off by pulling the power cord from the
socket or powering off a connected power strip or battery without first shutting down properly.
The Power button does not disconnect the instrument from the AC power supply. The only way to fully
power down the instrument is to unplug the AC power cord.
We recommend unplugging the instrument if it will remain unused for a long period of time.

Using MAUI
Using MAUI
MAUI, the Most Advanced User Interface, is Teledyne LeCroy'sunique oscilloscope user interface. MAUIis
designed for touch—all important controls for vertical, horizontal, and trigger are only one touch away.
Touch Screen
The touch screen isthe principal viewing and control center. The entire display area is active: use your
finger or a stylus to touch, drag, swipe, or draw a selection box.
Many controlsthat display information also work as “buttons” to access other functions. If you have a
mouse installed, you can click anywhere you can touch to activate a control; in fact, you can alternate
between clicking and touching, whichever isconvenient for you.
The touch screen isdivided into the following major control groups:
l Menu bar
l Grid area
l Descriptor boxes
l Dialogs
l Message Bar
17
HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual
Menu Bar
The top of the window contains a complete menu of functions. Making a selection here changes the
dialogs displayed at the bottom of the screen.
While many common operations can also be performed from the front panel or launched via the
descriptor boxes, the menu bar is the best way to access dialogsfor Save/Recall (File) functions, Display
functions, Status, LabNotebook, Pass/Fail setup, and Utilities/Preferences setup.
If an action can be “undone”, a small Undo button appears at the far right of the menu bar. Click this
to restore the oscilloscope to the state prior to the action.
Grid Area
The grid area displays the waveform traces. Every grid is 8 Vertical divisionsrepresenting 4096 Vertical
levels and 10 Horizontal divisions each representing acquisition time. The value represented by Vertical
and Horizontal divisionsdepends on the Vertical and Horizontal scale of the traces that appear on the grid.
Multi-Grid Display
The grid area can be divided into multiple gridsshowing different types and numbers of traces (in Auto
Grid mode, it will divide automatically as needed). Regardless of the number and orientation of grids, every
grid always represents the same number of Vertical levels. Therefore, absolute Vertical measurement
precision is maintained.
18
Different types of traces opening in a multi-grid display.
Using MAUI
Grid Indicators
These indicators appear around or on the grid to mark important points on the display. They are matched
to the color of the trace to which they apply. When multiple traces appear on the same grid, indicators
refer to the foreground trace—the one that appears on top of the others.
Axis labels
or change the Vertical/Horizontal scale. Originally shown in absolute values, the labels change to show delta
from 0 (center) when the number of significant digits grows too large. The number of labels that appear on
each grid depends on the total number of grids open. To remove them, go to Display > Display Setup and
deselect Axis Labels.
Trigger Time
Unless Horizontal Delay is set, this indicator is at the zero (center) point of the grid. Delay time is shown at the
top right of the Timebase descriptor box.
Pre/Post-trigger Delay
Delay has shifted the Trigger Position indicator to a point in time not displayed on the grid. All Delay values
are shown on the Timebase Descriptor Box.
Trigger Level
in Stop trigger mode, or in Normal or Single mode without a valid trigger, a hollow triangle of the same color
appears at the new trigger level. The trigger level indicator is not shown if the triggering channel is not displayed.
Zero Volts Level
the number and color of the trace.
Cursor markers
and-drop cursor markers to quickly reposition them.
Grid Intensity
mark the times/units represented by a grid division. They update dynamically as you pan the trace
, a small triangle along the bottom (horizontal) edge of the grid, shows the time of the trigger.
, a small arrow to the bottom left or right of the grid, indicates that a pre- or post-trigger
at the right edge of the grid tracks the trigger voltage level. If you change the trigger level when
is located at the left edge of the grid. One appears for each open trace on the grid, sharing

HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual
Descriptor Boxes
Trace descriptor boxes appear just beneath the grid whenever a trace is turned on. They function to:
l Inform—descriptors summarize the current trace settings and its activity status.
l Navigate—touch the descriptor box once to activate the trace, a second time to open the trace
setup dialog.
l Arrange—drag-and-drop descriptor boxes to move traces among grids.
l Configure—drag-and-drop descriptor boxes to change source or copy setups.
Besides trace descriptor boxes, there are also HD, Timebase and Trigger descriptor boxes summarizing
the acquisition settings shared by all channels, which also open the corresponding setup dialogs.
Channel Descriptor Box
Channel trace descriptor boxes correspond to analog signal inputs. They show
(clockwise from top left): Channel Number, Pre-processing list, Coupling, Vertical Scale
(gain) setting, Vertical Offset setting, Sweeps Count (when averaging), Vertical Cursor
positions, and Number of Segments (when in Sequence mode).
Codes are used to indicate pre-processing that has been applied to the input. The short

Dialogs
Dialogs appear at the bottom of the display for entering setup data. The top dialog will be the main entry
point for the selected functionality. For convenience, related dialogs appear as a series of tabs behind the
main dialog. Touch the tab to open the dialog.
Right-Hand Subdialogs
At times, your selections will require more settings than can fit on one dialog, or the task commonly invites
further action, such as zooming a new trace. In that case, subdialogs will appear to the right of the dialog.
These subdialog settings alwaysapply to the object that is being configured on the left-hand dialog.
Action Toolbar
Several setup dialogscontain a toolbar at the bottom of the dialog. These buttons enable you to perform
commonplace tasks—such as turning on a measurement—without having to leave the underlying dialog.
Toolbar actionsalways apply to the active trace.
Measure opens the Measure pop-up to set measurement parameters on the active trace.
Zoom creates a zoom trace of the active trace.
Math opens the Math pop-up to apply math functions to the active trace and create a new math trace.
Decode opens the main Serial Decode dialog where you configure and apply serial data decoders and
triggers. Thisbutton is only active if you have serial data software options installed.
Store loads the active trace into the corresponding memory location (C1, F1 and Z1 to M1; C2, F2 and Z2
to M2, etc.).
Find Scale performs a vertical scaling that fits the waveform into the grid.
Next Grid moves the active trace to the next grid. If you have only one grid displayed, a new grid willbe
created automatically, and the trace moved.
Label opens the Label pop-up to annotate the active trace.

LeCroy" normally appears.
You will see the word "Processing..." highlighted with red at the right of the message bar when the
oscilloscope is processing your last acquisition or calculating.
This willbe especially evident when you change an acquisition setting that affects the ADC configuration
in Normal or Auto trigger mode, such as changing the Vertical Scale, Offset, or Bandwidth. Traces may
briefly disappear from the display while the oscilloscope isprocessing.

OneTouch Help
Touch, drag, swipe, pinch, and flick can be used to create and change setups with one touch. Just as you
change the display by using the setup dialogs, you can change the setups by moving different display
objects. Use the setup dialogsto refine OneTouch actions to precise values.
As you drag & drop objects, valid targets are outlined with a white box. When you're moving over invalid
targets, you'll see the "Null" symbol ( Ø ) under your finger tip or cursor.
Note: Many actions shown here—such as Activate, Position Cursors, Change Trigger, Move Trace,
Scroll, Pan left/right, and Drag to Create Zoom—can be done on all MAUI instruments, even those
without the OneTouch features. Some examples below may show features not available on your
oscilloscope.
Turn On
To turn on a new channel, math, memory, or zoom trace, drag any descriptor box of the same type to the
Add New ("+") box. The next trace in the series will be added to the display at the default settings. It is now
the active trace.
If there is no descriptor box of the desired type on the screen to drag, touch the Add New box and choose
the trace type from the pop-up menu.
To turn on the Measure table when it is closed, touch the Add New box and choose Measurement.
Activate
Touch a trace or its descriptor box to activate it and bring it to the foreground. When the descriptor box
appears highlighted in blue, front panel controlsand touch screen gestures apply to that trace.
