Getting Started Manual
922172-00 Rev A 3
Observe all terminal ratings. Do not apply a voltage to any input
(C1, C2, C3, C4 or EXT) that exceeds the maximum rating of that
input. Refer to the front of the oscilloscope for maximum input
ratings.
Use only within operational environment listed. Do not use in wet
or explosive atmospheres.
Use indoors only.
Keep product surfaces clean and dry.
Do not block the cooling vents. Leave a minimum six-inch (15 cm)
gap between the instrument and the nearest object. Keep the
underside clear of papers and other objects.
Do not remove the covers or inside parts. Refer all maintenance to
qualified service personnel.
Do not operate with suspected failures. Do not use the product if
any part is damaged. Obviously incorrect measurement behaviors
(such as failure to calibrate) might indicate impairment due to
hazardous live electrical quantities. Cease operation immediately
and sequester the instrument from inadvertent use.
Operating Environment
Temperature: 10 to 40 °C.
Humidity: Maximum relative humidity 80 % for temperatures up to 31 °C
decreasing linearly to 50 % relative humidity at 40 °C (or at the upper
operational temperature limit).
Altitude: Up to 10,000 ft (3,048 m) at or below 25 °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.

Basic Controls
Front Panel
Getting Started Manual
The WaveSurfer MXs-B front
panel is designed to allow you to
operate basic oscilloscope
functions without having to open
software dialogs. Use the
Horizontal and Vertical controls as
you would for any other
oscilloscope. This topic provides
descriptions of the various
controls.
WaveSurfer MXs-B Oscilloscopes
8 922172-00 Rev A
Vertical Controls are multiplexed for each
channel. The lighted channel button indicates
which channel the controls are active for.
Turn channels ON by pressing the
corresponding channel button.
Channels are made active by pressing the
channel button again.
Turn channels OFF by pressing the channel
button (activating it), and then pressing again
to turn it OFF.
Inactive Channel
Active Channel
Vertical Controls
When a channel is active, its descriptor label changes appearance.
When a channel is turned OFF, the next channel in sequence becomes the
active channel.
If no front panel channel buttons are lit, it means either that no channels
are turned ON, or that a Math, Zoom, or Memory trace is active. In that
case, the vertical offset and sensitivity knobs adjust the vertical position
and vertical scale of the Math, Zoom, or Memory (Reference Waveform)
trace.
922172-00 Rev A 9
Horizontal Controls
Set up the timebase by using the front panel Horizontal
controls, just as for analog oscilloscopes. The
WaveSurfer MXs-B oscilloscope allocates memory as
needed to maintain the highest sample rate possible for
the timebase setting.
The WaveSurfer MXs-B oscilloscope can acquire in
either Real-Time up to 5 GS/s per channel, Random
Interleaved Sampling (RIS, up to 50 GS/s), or Roll mode
(up to 5 MS/s).
At certain very low time/division settings, the
oscilloscope defaults to RIS mode of operation to
maintain the highest sample rate.
At long time/division settings, the oscilloscope defaults
to Roll mode operation so the signal shown on the
screen are not delayed by the long acquisition time.
Maximum sample rate in Roll mode operation is 5 MS/s.
Stop
Cancels the capture in Auto, Normal, or Single trigger mode
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.
Setup
Displays the Trigger setup screen.

Probe and Signal Connection Interfaces
Teledyne LeCroy WaveSurfer MXs-B oscilloscopes contain probe interfaces
that provide a complete measurement solution from probe tip to
oscilloscope display. All probe interfaces permit automatic recognition of
connected probes. For active single-ended and differential voltage probes
and current probes, these interfaces upload data regarding the
attenuation, offset and units from the probe EEPROM's.
The Teledyne LeCroy WaveSurfer MXs-B oscilloscopes include ProBus
probe interfaces. The ProBus interface offers both 50 Ω/1 MΩ input
impedance and provides probe power and control for a wide range of
probes such as high impedance passive probes, high impedance active
probes, current probes, high voltage probes, and differential probes.
Probe Calibration
The passive probe supplied with your WaveSurfer MXs-B oscilloscope is
calibrated for the WaveSurfer MXs-B input impedance. If using other
passive probes with your WaveSurfer MXs-B oscilloscope, be sure to
calibrate them using the 1 kHz square wave signal available on the AUX
OUT terminal before using them for signal measurements.
Teledyne LeCroy offers a variety of other passive and active probes for use
with your WaveSurfer MXs-B Series oscilloscope. Visit teledynelecroy.com
for specifications and ordering information.

922172-00 Rev A 13
Passive Probe Compensation
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 your passive probe to any channel.
Connect the probe end to the CAL output connector at the front of the
oscilloscope. Ground the probe.
Adjust the trim pot at the connector end of the probe until the square
wave is as flat as possible.
Display Dashboard
The WaveSurfer MXs-B 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.
WaveSurfer MXs-B Oscilloscopes

Menu Bar
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
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.

The trigger delay Indicator is a color-coded triangle
that is positioned horizontally on the grid.
Trigger delay horizontally positions the
oscilloscope trace on the display so you can
observe the signal prior to the trigger time. It
adjusts the pre- and post-trigger time.
Grid Area
The grid area is divided into 8 vertical divisions and 10 horizontal divisions.
There are several indicators on the grid to help you understand the
following:
Trigger Delay setting
Trigger Level Setting
Trace Zero Level
These indicators are color-coded to the same color as the channel that the
oscilloscope is currently set to trigger on.
Trigger Delay Indicator
WaveSurfer MXs-B Oscilloscopes
16 922172-00 Rev A
Post-trigger delay is indicated by a color-coded
arrow pointing to the left.
All trigger delay values (including post-trigger
delay, shown here) are displayed in the timebase
descriptor label.
The trigger level Indicator is a color-coded triangle
that is positioned vertically on the grid.
In Stop trigger mode, the solid triangle also appears
with a hollow triangle of the same color if the level
is changed at that time. The hollow triangle
indicates what the trigger level is for the next valid
trigger.
The trigger level indicator is not shown if the
triggering channel is not displayed.
The zero volts level indicator is a color-coded label
that is positioned vertically on the grid.
Change the zero level by using the front panel
OFFSET knob in the VERTICAL control area. Rotate
this knob to adjust, or push to set to zero volts.
Push again to toggle back to the previous offset
setting.

922172-00 Rev A 17
Descriptor Labels
Channel trace labels show the vertical settings for
the signal. The title bar (colored area) of the label
shows the channel number on the far left.
Other information is indicated on the title bar, as
follows:
Coupling (AC 1M, DC 1M, DC 50, GND)
Deskew (DSQ) set to non-zero value
Bandwidth Limiting (BWL) ON
Averaging (AVG) ON
Interpolation
Inversion
Probe attenuation
Enhanced Resolution (ERES) ON
Some of these indicators may be abbreviated if
several are on at one time.
Touch a channel descriptor label once to make the
front panel vertical controls active for that channel.
Touch it again to open the software dialog for
further adjustment.
If cursors are ON, cursor information for this channel
appears on this trace label.
The title bar of the TimeBase (Horizontal) label
shows the trigger delay setting at the far right. Time
per division, sample rate, and number of samples
are indicated below the title bar.
Information is contained in rectangular boxes called descriptor labels.
These labels contain status information, and also act as shortcuts to the full
dialog when you touch them. Channel descriptor labels are displayed only
for channels that are turned on. Timebase and trigger descriptor labels are
always displayed.
Getting Started Manual
WaveSurfer MXs-B Oscilloscopes
18 922172-00 Rev A
Touch the timebase descriptor label once to open
the software dialog for further adjustment.
The title bar of the Trigger label shows the triggered
channel and the trigger coupling at the far right.
Trigger mode (Stopped), trigger type (Edge), level (0
mV), and slope (Positive) are indicated below the
title bar.
Touch the trigger descriptor label once to open the
software dialog for further adjustment.
Descriptor labels are also displayed for the math trace, zoom traces, and
memory (reference waveform) traces. These descriptor labels are only
displayed when their traces are turned ON.
Message Bar
At the bottom of the oscilloscope display is a narrow message bar. The
current date and time are displayed at the far right. Status, error, or other
messages are also shown in this area.
Alternative Access Methods
The front panel and display controls provide the most common ways to
access your oscilloscope’s capability. However, the instrument often gives
you more than one way to access dialogs and to make changes.
Top Menu Bar
If you prefer to drive the oscilloscope with the familiarity of Windows, you
might prefer to access dialogs from the menu bar at the top of the display.
This opens dialog boxes at the bottom of the screen, where adjustments
can be made.
The dialog area occupies the bottom one-third of the display. Expand the
signal display area by minimizing each dialog by touching the Close tab at
the right of the dialog box.
In some limited cases, the menu bar is the only way to access certain
functionality, but generally speaking, the most common oscilloscope
functionality can be controlled from the front panel.

Mouse and Keyboard Operation
In the procedures, we focus on using the front panel for common
operations, and the touch screen for making selections. But, if you have a
mouse connected to the instrument, you can click on objects instead of
touching them. Likewise, if you have a keyboard connected, you can use it
to enter data instead of using the virtual keyboard provided by the
instrument.
Turning on Channels and Traces
Connect a signal to a channel (we’ll assume you connected to channel 1 in
this example and that the channel was not already ON).
Press the channel 1 button on the front panel to turn on channel 1. The
button lights and the descriptor label for that channel are shown.
If the signal is not on the grid, press the AUTO trigger button and adjust
Horizontal and Vertical front panel controls to adjust the settings and
display the signal, or simply press the AUTOSETUP button to quickly bring
most repetitive signals onto the grid.
If you need to change probe attenuation, coupling,
or bandwidth limiting, open the channel setup dialog
for channel 1 by touching the descriptor label for
channel 1. Press this button twice if it is not the
active trace.
Or, use the Vertical Channel 1 Setup selection
from the menu bar to open the channel 1 setup
dialog.

At this point, the following dialog is shown at the bottom of the display,
and the grid area shortens until this dialog is closed (by touching the Close
button on the upper right hand corner of this dialog).
Vertical Setup
Coupling
Coupling choices are as follows:
DC 50 Ω
GROUND
DC 1 MΩ
AC 1 MΩ
Select coupling by touching inside the Coupling field and choosing a
coupling mode from the pop-up menu.
NOTE: The coupling choices for a channel change if a ProBus probe is
connected to a channel.
Deskew
Deskew allows you to compensate for different lengths of cables, probes,
or anything else that might cause timing mismatches between signals.
Connect all probes to the desired channels, then probe a common signal
with each probe and adjust for timing differences using Deskew.
Probe Attenuation
If you use a Teledyne LeCroy ProBus compatible active probe, or a probe
compatible with Probe Ring, the attenuation is automatically set by the
oscilloscope. If it is not automatically set, select a value here by touching
inside the Probe Atten field selecting a value from the pop-up menu.

Bandwidth Limiting
You may sometimes want to limit high frequency noise on a very low
bandwidth input signal. If this is the case, you can limit the channel
bandwidth to less than the full bandwidth of the oscilloscope. Select a
different bandwidth by touching inside the Bandwidth field and selecting a
value from the pop-up menu.
Averaging Your Signal
The WaveSurfer MXs-B oscilloscope allows you the opportunity to
continuously average your signal to reduce signal noise and aid in signal
evaluation. If you want to use averaging, select a value here by touching
inside the Averaging field and entering a value up to 1 million sweeps on
the pop-up keypad.
Interpolation Settings
Linear interpolation, which inserts a straight line between sample points, is
best used to reconstruct straight-edged signals such as square waves.
(Sinx)/x interpolation, on the other hand, is suitable for reconstructing
curved or irregular wave shapes, especially when the sample rate is 3 to 5
times the system bandwidth.
Noise Filtering (ERES)
The instrument's enhanced resolution feature improves vertical resolution
by a fixed amount for each filter. This real increase in resolution occurs
whether or not the signal is noisy, or your signal is single-shot or repetitive.
The signal-to-noise ratio (SNR) improvement you gain is dependent on the
form of the noise in the original signal. The enhanced resolution filtering
decreases the bandwidth of the signal, filtering out some of the noise.
Using Shortcut Toolbar
These shortcut buttons can be used to perform specific actions for the
channel corresponding to the current setup dialog.
For more information on Measure, Zoom, Math, and Memories (Reference
Waveforms), refer to the section dealing with that subject.

Opens a Measurement selection pop-up menu. You can then
select up to 6 parameters (measurements) for the active
channel from this menu without leaving the Channel Setup
dialog. The parameter automatically appears below the grid.
Creates a zoom trace of the channel signal. The zoom trace
becomes active, and you can use the Vertical and Horizontal
controls to modify its scale and position.
Opens a Math selection pop-up menu. You can then select a
math function for the active channel from this menu without
leaving the Channel Setup dialog. The Math trace is then
displayed in its own grid.
Copies the channel trace into its corresponding Memory
(Reference Waveform) location. For instance, C1 is loaded
into M1, C2 is loaded into M2, etc.
Automatically performs a vertical scaling that fits the
waveform into the grid.
Opens a Labeling pop-up menu that allows user-defined
labels tied to the waveform.
TimeBase
Timebase Setup and Control
Set up the Timebase by using the front panel Horizontal controls or the
Timebase menu bar, trace descriptor label and dialog box.
1. Touch Timebase → Horizontal Setup on the menu bar. The
Timebase dialog is shown.
2. Touch inside the Time/Division data entry field and enter a value.
3. Touch inside the Delay data entry field and enter a value.
