Getting Started Manual
Operating Environment
Temperature: 5 to 40 °C
Humidity: Maximum relative humidity 80% for temperatures up to 31
decreasing linearly to 50% relative humidity at 40 °C.
Altitude: Up to 2,000 m
NOTE: Direct sunlight, radiators, and other heat sources should be taken into
account when assessing the ambient temperature.
°C
Cooling
The instrument relies on forced air cooling with internal fans and vents. Take
care to avoid restricting the airflow to any part of the oscilloscope. Around the
sides and rear, leave a minimum of 15 cm (6 inches) between the instrument
and the nearest object. At the bottom, the oscilloscope feet (up or down)
provide adequate clearance.
CAUTION. Do not block oscilloscope vents. Always keep the area
beneath the oscilloscope clear of paper and other items.
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 oscilloscope using a damp, soft cloth. Do not use
harsh chemicals or abrasive elements. Under no circumstances submerge the
instrument or allow moisture to penetrate it. Avoid electric shock by
unplugging the power cord from the AC outlet before cleaning.
CAUTION. Do not attempt to clean internal parts. Refer to qualified
service personnel.
922138-00 Rev A 3B
WaveRunner Xi-A and MXi-A Oscilloscopes
Power Consumption
The instrument operates from a single-phase, 100 to 240 V
power source at 50/60 Hz (+/-5%), or single-phase 100 to 120 V
power source at 400 Hz (+/-5%).
No manual voltage selection is required because the instrument automatically
adapts to line voltage.
Depending on the accessories installed (front panel probes, PC port plug-ins,
etc.), the instrument can draw up to 340 Watts (340 VA) max - all 4 channel
models and 290 Watts (290VA) - all 2 channel models. Power consumption
during Standby State: 12 watts – all models.
NOTE: The instrument automatically adapts itself to the AC line input within
the following ranges:
Voltage Range: 90 to 264 Vrms 90 to 132 Vrms
Frequency Range: 47 to 63 Hz 380 to 420 Hz
(+/-10%) AC
rms
(+/-10%) AC
rms
Power and Ground Connections
The instrument is provided with a grounded cord set containing a molded
three-terminal polarized plug and a standard IEC320 (Type C13) connector for
making a line voltage and a safety ground connection. The AC inlet ground
terminal is connected directly to the frame of the instrument. For adequate
protection against electrical shock hazard, the power cord plug must be
inserted into a mating AC outlet containing a safety ground contact. Use only
the power cord specified for this instrument and certified for the country of
use.
WARNING. Any interruption of the protective conductor inside or
outside of the scope, or disconnection of the safety ground terminal
creates a hazardous situation. Intentional interruption is prohibited.
The oscilloscope should be positioned to allow easy access to the socketoutlet. Power is completely removed from the oscilloscope by unplugging the
power cord from the AC outlet.
The power cord should be unplugged from the AC outlet if the instrument is
not used for an extended period of time.
4 922138-00 Rev A
Getting Started Manual
CAUTION. The outer shells of the front panel terminals (CH1, CH2, CH3,
CH4, EXT) are connected to the instrument chassis, and therefore to the
safety ground.
WARNING. Interrupting the protective conductor inside or outside the
oscilloscope, or disconnecting the safety ground terminal, creates a
hazardous situation. Intentional interruption is prohibited.
Standby Power
The Power (Standby) button controls the operational state of the
oscilloscope. Press the button to switch the instrument On or into Standby
mode (Off).
Always use the Power button or the File > Shutdown menu option to execute a
proper shut down process and preserve settings before powering down.
Powering off does not disconnect the oscilloscope from the AC power supply.
The only way to fully power down the instrument is to shut down then unplug
the AC power cord from the outlet.
We recommend unplugging the instrument if it will be unused for a long
period of time.
Calibration
The recommended calibration interval is one year. Calibration should be
performed by qualified personnel only.

922138-00 Rev A 11B
WaveRunner Xi-A and MXi-A Oscilloscopes
Current
Probes
Current Probes measure the current passing through a wire. They do
not use the traditional probing style of placing a tip onto a test point.
Instead, a wire is placed inside of the jaw of the probe, which then
allows the probe to measure the current (in Amps).
Active
Probes
There are two different types of active probes: single-ended and
differential.
Single-ended: A single-ended active probe is associated with
measuring voltages at high frequencies. Measurement with an active
probe requires a test point and a ground point. The ground (also
called earth) acts as a zero reference for the test point measurement.
Differential: Differential active probes are like two probes in one.
Instead of measuring a test point in relation to a ground point (like
single-ended active probes), differential probes measure the
difference in voltage of a test point in relation to another test point.
Passive
Probes
Passive probes measure voltages at lower frequencies (<400 MHz).
They have higher input capacitance (input C) and do not need power
to operate (unlike active probes). At higher frequencies, higher input
capacitance loads the test circuit, attenuating the signal. This is why
active probes are used in high frequency applications. Passive probes
also measure voltage in reference to ground.
High
Voltage
Probes
These are active single ended probes that are designed to measure
high voltages (safely). They measure the voltage in reference to
ground.
Probes
Your WaveRunner Xi oscilloscope is supplied with one passive probe for each
channel. The supplied passive probe has a high-input resistance and low
capacitance make it ideal for general purpose probing of signals with
frequency content from DC through several hundred MHz. The supplied
passive probe has a large selection of connection accessories, supplied
standard with the probe and available from Teledyne LeCroy as optional
accessories.
Teledyne LeCroy also offers a variety of passive and active probes for use with
your WaveRunner Xi Series oscilloscope. Visit teledynelecroy.com for
specifications and ordering information.
12 922138-00 Rev A
Getting Started Manual
Passive probes must be compensated to flatten overshoot. This is
accomplished by means of a trimmer at the connector end of the probe.
Attach the connector end of supplied passive probe to any channel.
Connect the probe end to the CAL output connector at the front of the
oscilloscope.
Adjust the trim pot at the connector end of the probe until the square wave is
as flat as possible.

Getting Started Manual
Front Panel Buttons and Knobs
The control buttons of the WaveRunner Xi Series front panel are logically
grouped into analog and special function areas. Analog functions are included
in the Horizontal, Trigger, and Vertical groups of control buttons and knobs.
The following table provides an explanation of the front panel push buttons
and knobs:
Trigger Controls

threshold level. The Level is
indicated in the Trigger
descriptor label:
Push the LEVEL knob to have the oscilloscope find the level automatically.
SETUP - Displays the trigger setup dialog. Push the button again to close the
dialog.
AUTO - Triggers the oscilloscope after a time-out, even if the trigger
conditions are not met.
NORMAL - Triggers the oscilloscope each time a signal is present that meets
the conditions set for the type of trigger selected.
SINGLE - Arms the oscilloscope to trigger once (single-shot acquisition)
when the input signal meets the trigger conditions set for the type of
trigger selected. If the oscilloscope is already armed, it forces a trigger.
STOP - Prevents the oscilloscope from triggering on a signal.
922138-00 Rev A 15B
WaveRunner Xi-A and MXi-A Oscilloscopes
Horizontal Controls
DELAY - Horizontally positions the oscilloscope trace on the
display so you can observe the signal prior to the trigger time.
Push the button to reset the delay to zero. A second push
returns the delay to the previous setting. Delay adjusts the
pre- and post-trigger time.
TIME/DIVISION - Sets the time/division of the oscilloscope
timebase (acquisition system).
Vertical Controls
OFFSET - Adjusts the vertical offset of a channel.
VOLTS/DIV - Adjusts the Volts/Division setting (vertical
gain) of the channel selected.
CHANNEL BUTTONS - If the channel is already ON, the
channel button makes the channel active. If the
channel is OFF, the channel button turns the channel
ON. When the channel is active, the channel button
is lit, and the Offset and Volts/Div knobs are
dedicated to that channel.
Zoom Control Knobs
QUICKZOOM - Automatically displays magnified
views of up to four signal inputs on multiple grids.
With four input signals, the signals are displayed
along with four zoom traces, each on its own grid.
This button turns off all other traces and redefines all
math functions to be zooms of channels.
POSITION - Adjusts the horizontal position of a
zoom trace on the display. The zoom region is
highlighted in color on the source trace. Unlike Delay, the position is not
calibrated to the trigger position.
ZOOM - Adjusts the horizontal zoom (magnification factor) of the
selected zoom trace.
16 922138-00 Rev A
Getting Started Manual
POSITION - Adjusts the vertical position of the selected zoom trace on
the display. Unlike Offset, the position is not calibrated to the 0 V
reference.
ZOOM - Adjusts the vertical zoom (magnification factor) of the selected
zoom trace on the display.
INDICATOR LAMPS - The three lamps at the bottom of the panel are lit
according to the kind of trace you are zooming, or whose position you are
adjusting: channel trace, math trace, or memory trace. The exact trace
that is active has a solidly colored descriptor label.
Special Features Controls
INTENSITY - This knob adjusts the intensity of your trace.
Pushing the button toggles between WaveStream fastviewing mode and real-time mode.
WAVESTREAM LAMP - This lamp lights when the
oscilloscope is displaying in WaveStream fast-viewing
mode.
CURSOR TYPE - This push button turns on the cursors,
then cycles through the four different cursor types with
each additional push:
ADJUST FINE - This dual-function knob controls the
placement of the top or left cursor. When the knob is
in Cursor mode, the CURS lamp is lit.
When you click in any data entry field in any dialog, the
knob automatically switches from cursor placement mode
to adjustment mode, and the ADJ lamp lights. This allows you to dial in
fine-grained values. When you close the dialog, the knob reverts to cursor
placement mode.
922138-00 Rev A 17B
WaveRunner Xi-A and MXi-A Oscilloscopes
ADJUST COARSE - This dual-function knob controls the placement of the
bottom or right cursor. When the knob is in Cursor mode, the CURS lamp
is lit.
When you click in any data entry field in any dialog, the knob
automatically switches from cursor placement mode to adjustment mode,
and the ADJ lamp lights. This allows you to dial in coarse-grained values.
When you close the dialog, the knob reverts to cursor placement mode.

Understanding Display Information
The WaveRunner Xi-A oscilloscope’s display contains valuable information
about the current settings of your Vertical (channel), Horizontal (Timebase),
and Trigger controls. In addition, there are many shortcuts that are available
by using the touch screen capability of your display to quickly access
information or to open dialogs.
Top Menu Bar (File Menu)
The top menu bar provides access to various software dialogs. It is very similar
to the File menu on any Windows program. For common oscilloscope
operations, you don’t need to use the top menu bar (since you can access
most dialogs from the Front Panel or from the Descriptor Labels). However, it
is the only way to access setup or other dialogs for the following:
Display Setup
Save or Recall Waveform
Save or Recall Setups
Print Setup
Vertical (Channel), Horizontal, or Trigger Status
Memory (Reference Waveform) Setup
Pass/Fail Setup
Utilities and Preferences Setup
Help Access
922138-00 Rev A 19B
WaveRunner Xi-A and MXi-A Oscilloscopes
Trigger Delay - This indicator is located along
the bottom edge of the grid. Trigger delay
allows you to see the signal prior to the trigger
time.
All trigger delay values (including post-trigger
delay, shown here) are displayed in the
Timebase Descriptor Label. Zero delay is the
horizontal center of the oscilloscope display.
The default setting (Time) is for the delay to be
read out in seconds, and to move
proportionately when the timebase knob is
turned. If you want to set delay (Div) to a fixed
position on the grid and then have it stay fixed
as the timebase changes, go to Utilities,
Preferences, Acquisition.
At the right-hand end of the top menu bar is an Undo button.
This button appears after the AutoSetup front panel button is pressed, and
after Zooming. If you want to perform an Undo operation, it must be the very
next operation after you perform the Autosetup or Zoom operation.
Grid Area
The grid area is divided into 8 vertical divisions and 10 horizontal divisions just
like any other oscilloscope. There are several indicators on the grid to help you
understand the following:

pointing arrow below-left of the grid. Pretrigger delay is indicated by a right-pointing
arrow below-right of the grid.
Trigger Level - This indicator is located at the
right edge of the grid. It tracks the trigger level
as you reposition the trace up or down, or
change scale. When triggering is stopped, a
hollow arrow indicates where the new level
ends up when triggering resumes.
Push the LEVEL knob to reset the level to 50%.
Zero Volts Level - This indicator is located at
the left edge of the grid. Change the zero volts
level by turning the VERTICAL OFFSET knob. Push
the knob to reset the indicator to the middle
of the grid.
Channel trace labels show the vertical settings for
the trace, as well as cursor information if cursors
are in use. In the title bar of the label are also
included indicators for (SinX)/X interpolation,
waveform inversion (INV), deskew (DSQ),
coupling, bandwidth limiting (BWL), and averaging
(AVG). These indicators have a long and short
form:
Trace Descriptors
Vertical and horizontal trace descriptor labels are displayed below the grid.
They provide a summary of your channel, timebase, and trigger settings.
Adjust these settings by touching the respective label (its corresponding setup
dialog is then shown).

Besides channel traces, math and memory trace
labels are also displayed. Labels are displayed only
for traces that are turned on.
As a visual aid, an active channel (i.e., the one
whose settings can be adjusted by the front panel
knobs) is displayed in solid color.
The title bar of the TimeBase label shows the
trigger delay setting. Time per division and
sampling information is given below the title bar.
The title bar of the Trigger label shows the trigger
mode: Auto, Normal, or Stopped. Below the title
bar is given the coupling (DC), trigger type (Edge),
source (C1), level (0 mV), and slope (Positive).
Shown below the Timebase and Trigger labels is
value information for horizontal cursors, including
the time between cursors and the frequency.
Dialog Boxes
The lower portion of the screen contains dialogs where information is shown,
selections are made, and data is input. Typically, the dialogs are organized into
tabular displays, subtabs, or pop-up dialogs. The dialog area is controlled by
touch screen buttons and front panel buttons.
The following Dialog Area controls also provide assistance when entering data:
Message Bar
The message bar continually displays the time and date. It also displays
oscilloscope status and error messages.
