These give extended warranty and allow you to budget maintenance costs after the initial three-year warranty has expired. Installation, training, enhancements, and on-site repairs, among other services, are available through special supplemental support agreements. Inquire at your LeCroy customer service center or national distributor.
GETTING STARTED MANUAL Restarting the Application Upon initial power-up, the oscilloscope loads the instrument application software automatically.
WAVESURFER MXS-B OSCILLOSCOPE BASIC CONTROLS 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.
GETTING STARTED MANUAL Vertical Controls 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. When a channel is active, its descriptor label changes appearance.
WAVESURFER MXS-B OSCILLOSCOPE 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. Acquisition Mode 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).
GETTING STARTED MANUAL AutoSetup Button Automatically sets timebase, trigger, and sensitivity to display a wide range of repetitive signals. Measure, Zoom, and Math Quick Buttons Measure – Press once to open the measure dialog. Press again to close the dialog. QuickZoom – Press once to create zooms of all displayed channels. Press again to unzoom. Math – Press once to turn on the Math trace, and display the Math Setup dialog. Press again to close the dialog.
WAVESURFER MXS-B OSCILLOSCOPE Adjust Knob The adjust knob can be used to make adjustments to a value when a dialog is open and the selected control has a yellow highlight. Push the knob in to toggle between coarse and fine adjustments. Print Button This button can be programmed to print the screen to a file, a printer, or the clipboard. It can also send the file as an e-mail attachment. Select the instrument and format it under the Utilities Hardcopy dialog.
GETTING STARTED MANUAL Intensity/Acquisition Mode The INTENSITY knob adjusts the brightness of your trace. Pushing the button toggles between WaveStream fast-viewing mode (indicator lamp on) and real-time mode (lamp off). PROBE AND SIGNAL CONNECTION INTERFACES 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.
WAVESURFER MXS-B OSCILLOSCOPE 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. 1. Attach the connector end of your passive probe to any channel. 2. Connect the probe end to the CAL output connector at the front of the oscilloscope. Ground the probe. 3. Adjust the trim pot at the connector end of the probe until the square wave is as flat as possible.
GETTING STARTED MANUAL 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).
WAVESURFER MXS-B OSCILLOSCOPE 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.
GETTING STARTED MANUAL Trigger Delay Indicator 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. Post-trigger delay is indicated by a color-coded arrow pointing to the left.
WAVESURFER MXS-B OSCILLOSCOPE Zero Level Indicator 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. Descriptor Labels Information is contained in rectangular boxes called descriptor labels.
GETTING STARTED MANUAL 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. 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.
WAVESURFER MXS-B OSCILLOSCOPE 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.
GETTING STARTED MANUAL 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.
WAVESURFER MXS-B OSCILLOSCOPE 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.
GETTING STARTED MANUAL Using Toolbar Shortcuts These toolbar shortcuts 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.
WAVESURFER MXS-B OSCILLOSCOPE 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. Setting up additional timebase setup and controls 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.
GETTING STARTED MANUAL SAMPLING MODES Depending on your timebase, the following sampling modes are available: WaveStream Mode - This fast viewing mode provides brightnessgraded intensity with a decay time similar to the action of phosphor on an analog screen. WaveStream mode operates at up to 10 GS/s with an update rate up to 22,000 waveforms/second for better capture of higher frequency abnormal events.
WAVESURFER MXS-B OSCILLOSCOPE Single-shot Sampling Mode Basic Capture Technique A single-shot acquisition is a series of digitized voltage values sampled on the input signal at a uniform rate. It is also a series of measured data values associated with a single trigger event. The acquisition is typically stopped a defined number of samples after this event occurs: a number determined by the selected trigger delay and measured by the timebase.
GETTING STARTED MANUAL Sequence Sampling Mode – Working with Segments Using Sequence Mode, you can store up to 15,000 triggered events as segments into the oscilloscope's memory. This is ideal when capturing many fast pulses in quick succession or when capturing few events separated by long time periods. The instrument can capture complicated sequences of events over large time intervals in fine detail, while ignoring the uninteresting periods between the events.

GETTING STARTED MANUAL RIS Sampling Mode - For Higher Sampling Rates RIS (Random Interleaved Sampling) is an acquisition technique that allows effective sampling rates higher than the maximum single-shot sampling rate. It is used on repetitive waveforms with a stable trigger. The maximum effective RIS sampling rate is achieved by making multiple single-shot acquisitions at maximum real-time sample rate. The bins thus acquired are positioned approximately 5 ps (200 GS/s) apart.
WAVESURFER MXS-B OSCILLOSCOPE Roll Mode Roll mode displays, in real time, incoming points in single-shot acquisitions that have a sufficiently low data rate. The oscilloscope rolls the incoming data continuously across the screen until a trigger event is detected and the acquisition is complete. The parameters or math functions connected to each channel are updated every time the roll mode buffer is updated, as if new data is available.
GETTING STARTED MANUAL TRIGGERING Overview The oscilloscope uses many waveform capture techniques that trigger on features and conditions that you define. These triggers fall into two major categories: Edge activated by basic waveform features or conditions such as a positive or negative slope, and hold-off SMART Trigger® sophisticated triggers that enable you to use basic or complex conditions for triggering.
WAVESURFER MXS-B OSCILLOSCOPE Trigger Setup Trigger Delay 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. Delay adjusts the pre- and post-trigger time. Pre-trigger delay is adjustable from 0-100% Post-trigger delay is indicated by a color-coded arrow pointing to the left.
GETTING STARTED MANUAL Trigger level is specified in volts and remains unchanged when you change the vertical gain settings or offset. The amplitude and range of the trigger level are limited as follows: ± 4.1 screen divisions with a channel as the trigger source ± 0.5 V with EXT as the trigger source ± 5 V with EXT/10 as the trigger source None with LINE as the trigger source (zero crossing is used). Edge Trigger Set Up 1. Touch the trigger descriptor label at the bottom right of the display.
WAVESURFER MXS-B OSCILLOSCOPE 6. 7. DC - All the signal’s frequency components are coupled to the trigger circuit for high frequency bursts or where the use of AC coupling would shift the effective trigger level. AC - The signal is capacitively coupled. DC levels are rejected, and frequencies below 50 Hz are attenuated. LFREJ - The signal is coupled through a capacitive high-pass filter network, DC is rejected and signal frequencies below 50 kHz are attenuated.

WAVESURFER MXS-B OSCILLOSCOPE Trigger Holdoff Holdoff is an optional, additional condition of Edge trigger. It can be set either as a period of time or as an event count. Holdoff disables the trigger circuit for a given period of time or events after the last trigger occurred. Events are the number of occasions on which the trigger condition is met. The trigger occurs again when the holdoff elapses and the edge trigger’s other conditions (for level, slope, etc.) are met.
GETTING STARTED MANUAL TV Serial TV triggers provide stable triggering on standard or custom composite video signals. Use them on PAL, SECAM, or NTSC systems. Support for HDTV triggering on 1080i, 1080p, and 720p formats is included. Use CUSTOM setup for other standards. Serial trigger allows a serial trigger condition to be set from within the oscilloscope, using an easy-to-understand interface.
WAVESURFER MXS-B OSCILLOSCOPE SERIAL TRIGGER AND DECODE (OPTIONAL) Optional WaveSurfer MXs-B capabilities support triggering and decoding of many serial data protocols. Please refer to the LeCroy website for a list of supported standards. The serial triggers are integrated into the oscilloscope. All serial triggers are selected through the normal oscilloscope trigger menus. Serial data signals are input to the oscilloscope through probes.
GETTING STARTED MANUAL Serial Decode and Decode Setup These dialogs provide the ability to set the oscilloscope up for protocol decoding of serial data messages, with display of the protocol data overlaid on the signal. They also allow quick and easy access to oscilloscope zooming, searching, table display, and table export. The serial decode and decode setup dialogs are accessed in any the following ways: 1. Touch Analysis Serial Decode... from the menu bar. 2.
WAVESURFER MXS-B OSCILLOSCOPE Touch a Channel, Memory, or Math trace to open a pop-up dialog that displays a shortcut to the Decode Setup dialog box Please refer to the Low Speed Serial Data Trigger manual or the Online Help on your oscilloscope for Serial Trigger information and details.
GETTING STARTED MANUAL VIEWING WAVEFORMS Display Setup Note: Not all grid styles are available on all instruments. To set up your display, touch Display →Display Setup on the menu bar. Grid Touch one of the Grid combination buttons (for example, Single, Combination XY, XYSingle). Autogrid automatically adds or deletes grids as you buttons select more or fewer waveforms to display. Touch inside the Grid Intensity data entry field to choose the intensity.
WAVESURFER MXS-B OSCILLOSCOPE Zooming your Channels LeCroy offers extremely powerful, yet simple to use, zooming capability in the WaveSurfer MXs-B oscilloscope. The large, bright 10.4” display with touch screen lends itself very well to quickly creating zooms, and seeing how they relate to the original channels. There are a number of different ways to zoom in a WaveSurfer MXs-B oscilloscope: Drawing a box around the zoom area, using either your finger or a mouse/pointing tool.
GETTING STARTED MANUAL You can also use touch screen zoom to change the zoom scale of an existing Zoom, Math, or Memory (reference waveform) trace. When you zoom a waveform by this method, a representation of the zoom area appears in a thumbnail Preview in the Zx dialog (lower-right). FRONT PANEL QUICKZOOM BUTTON Pressing the front panel QuickZoom button creates Zoom traces for all channels shown.
WAVESURFER MXS-B OSCILLOSCOPE TOOLBAR ZOOM Press the toolbar Zoom button in the Cx Vertical Adjust dialog for the channel trace you want to zoom. A Zoom trace is created for the selected channel. UNDO your zoom by pressing the Undo button in the upper-right corner of the display, or pressing the front panel QuickZoom button again. Zoom Descriptor Label When a Zoom trace is ON, there is a descriptor label on the display for it, much like for the channels, math trace, and memories (reference waveforms).
GETTING STARTED MANUAL Adjusting Zoom Scale and Position USING FRONT PANEL CONTROLS It is easy to adjust your Zoom trace’s scale and position. The WaveSurfer MXs-B oscilloscope multiplexes the Vertical and Horizontal Front Panel controls to control the zoom scale and position. This is done automatically after you have created the zoom trace, and remains this way until you make a Channel, Math trace, or Memory (reference waveform) active.
WAVESURFER MXS-B OSCILLOSCOPE Using Zoom Dialog Controls You can also use the Zoom dialog controls to adjust zoom. Touch the descriptor label to open the Zoom dialog. Then use the on-screen zoom controls to change the horizontal and vertical position and scale. Horizontal scale adjustments always apply to all waveforms. Using Toolbar Shortcuts These toolbar shortcuts can be used to perform specific actions for each Zoom trace. Opens a Measurement selection pop-up menu.
GETTING STARTED MANUAL ANALYZING WAVEFORMS Measuring with Cursors Overview Cursors are important tools that help when measuring signal values. Cursors can be moved around on the waveform to identify specific voltage and time values on the waveform. Use cursors to make fast, accurate measurements and to eliminate guesswork. The cursor controls contain two dedicated cursor knobs and a Type button.
WAVESURFER MXS-B OSCILLOSCOPE Cursor Types Horizontal (Time) Horizontal (Time) cursors are moved left and right along the waveform. Place them at a desired location along the time axis to read the signal’s time and amplitude information at the selected location. Vertical (Amplitude) Vertical cursors are lines that you move up and down on the grid to measure the amplitude of a signal. Horizontal (Frequency) Horizontal (Frequency) cursors are moved left and right along the FFT Math trace.
GETTING STARTED MANUAL Tracking Cursors Lock the cursors together by checking the Track checkbox on the Cursors dialog (Cursors Cursor Setup… from menu bar). This sets the cursors to move in unison while adjusting their position. Reading Cursor Information Cursor information is displayed in two different places on the WaveSurfer MXs-B oscilloscope display.
WAVESURFER MXS-B OSCILLOSCOPE MEASURING WITH PARAMETERS Overview Parameters are pre-programmed measurements that eliminate the need to set up cursors for standardized measurements, like rise time, fall time, peak-peak amplitude, etc. Use them to automatically calculate many attributes of your waveform. You can make common measurements on one or more waveforms, and display up to six parameter measurements at one time.
GETTING STARTED MANUAL 2. 63 The default status has parameters turned OFF, and all are undefined (None).
WAVESURFER MXS-B OSCILLOSCOPE 3. Touch any of the icons to select the desired measurement. Scroll down through the list using the slider bar on the right side of the pop-up menu.
GETTING STARTED MANUAL 4. The channel source defaults to C1. Touch inside the Source field to select a different source (a channel, a math function, a memory, or a zoom). 5. Add additional parameter measurements to the display by selecting other parameters (labeled as P1 through P6) as previously described. Close the measure dialog by either pressing the front panel Measure button again, or touching Close on the on-screen dialog. 6.
WAVESURFER MXS-B OSCILLOSCOPE Understanding Parameter Displays The Parameter Display Format Understanding the information in the parameter displays is easy. The following table explains what each abbreviation means, following the parameter display from left to right, and top to bottom. The format is Px:Name(source) with value and status contained as follows: P1, P2, P3, The number of the parameter measurement. P means Parameter. P4, P5, P6 Each parameter is uniquely identified.
GETTING STARTED MANUAL Parameter Gates (Windows) Sometimes you might want a parameter measurement on a specific portion of your signal, and ignore all other portions. When this is the case, you can use Measure Gate. Measure Gate is controlled in the Measure dialog, and is set in grid divisions. Set the gate by touching the Start field to highlight the control (shows in yellow), and then use the adjust knob to dial the location of the start gate. Repeat the same process for the Stop gate.
WAVESURFER MXS-B OSCILLOSCOPE Viewing Thumbnail Histograms Histicons are miniature histograms of parameter measurements that appear below the grid. These thumbnail histograms let you see at a glance the statistical distribution of each parameter. Turning Off Parameters You can turn all parameters OFF by touching the Turn All Off button in the Measure dialog. This also redefines all the parameter definitions to NONE.
GETTING STARTED MANUAL WaveScan™ Advanced Search and Analysis Introduction to WaveScan WaveScan enables you to search for unusual events in a single capture, or to scan for an event in many acquisitions over a long period of time. You can select from more than 20 search modes (frequency, rise time, runt, duty cycle, etc.), apply a search condition (slope, level, threshold, hysteresis), and begin scanning in a post-acquisition environment.
WAVESURFER MXS-B OSCILLOSCOPE Signal Views WaveScan provides distinct views of your signal: Source view highlights all occurrences of edges that meet your criteria. Zoom view allows you to expand a waveform feature vertically and horizontally; to apply further processing; to store it, or to apply a descriptive label to the feature. Note: The number of grids displayed varies from depending on which views are enabled.
GETTING STARTED MANUAL Sampling Mode Whenever WaveScan is enabled, the instrument reverts to Real-time sampling mode. SOURCE VIEW The top trace on the screen is the source (channel, math, memory) trace. This trace shows all captured edges and highlights those that fit your search criteria. For example, in this figure we are searching for slow rising edges that fall outside a time window: In this acquisition, WaveScan has located eleven edges that fit the search criteria (filter) of greater than 1.
WAVESURFER MXS-B OSCILLOSCOPE Zoom View An individual edge can be zoomed by selecting it from the table of found events at the left of the screen. You can also scroll through the table using the Prev/Next scroll buttons in the Search dialog, or select an event by touching inside the Idx field and entering an index number, using the popup keypad. Front panel ZOOM controls can be used to vary the magnification and position of the zoomed trace. Or, you can use the on-screen In/Outbuttons.
GETTING STARTED MANUAL In Zoom View, you can also apply further processing, store, or apply a descriptive label to the zoom trace. Edge Mode This search mode locates all edges in an acquisition and presents them time-stamped in a table. You can select positive, negative, or both edges. When the acquisition is stopped, scan filters contained in Measurements mode can be applied to the edges to find specific characteristics.
WAVESURFER MXS-B OSCILLOSCOPE As with other search modes, a trigger action can be set for Edge mode also. Non-monotonic Mode The Non-monotonic search mode looks for edges that cross a threshold more than once between high and low levels. All events that meet the criteria of slope, hysteresis, and level are presented in a table and highlighted in the source trace. The value displayed in the table is the difference of the max. and min. of the non-monotonicity.
GETTING STARTED MANUAL This can be confirmed with cursors: The hysteresis value is used to eliminate noise. A non-monotonicity is detected only when its amplitude is greater than the hysteresis. Therefore, when setting a hysteresis level, set a value that is greater than the amplitude of the noise. Runt Mode This search mode looks for pulses that fail to transit a given region. You can search for positive-going or negative-going runts, or both. An adjustable hysteresis band is provided to eliminate noise.
WAVESURFER MXS-B OSCILLOSCOPE This can be confirmed by placing cursors on the runt pulse and reading the delta Y value in the trace labels: In the case of positive-going runt pulses, the value displayed in the table is the absolute value of the amplitude of the runt pulse: WSMXs-B-GSM-E Rev A 76
GETTING STARTED MANUAL Measurement Mode This search and scan mode lets you apply filters to your acquisitions to highlight only the features of interest. Post-acquisition, you can apply other filters to the acquisition, or make different parameter measurements on it. For example, in this acquisition a Rise time (10-90%) parameter measurement is applied to fast edges during acquisition. We are interested only in edges with a rise time slower than 37 ns.
WAVESURFER MXS-B OSCILLOSCOPE SCAN FILTERS But, now we want to look at fall times greater than 45.5 ns; 3 falling edges from the same acquisition pass this new filter: You can also decide how anomalous the features located should be by using the Filter Wizard to select the average value as the limit, to search for rarest events, or to apply statistical criteria.
GETTING STARTED MANUAL In the following example, there were several slow edges in a repetitive waveform. For each filtering method selectable from the wizard, the rise time used as the filter limit and delta are calculated automatically. Filter Methods While the Filter Wizard provides a quick way to apply filtering criteria automatically, the Filter Method menu and related fields let you manually set up filtering criteria.
WAVESURFER MXS-B OSCILLOSCOPE WORKING WITH SAMPLING MODES Sequence Mode Setup When setting up Sequence Mode, you define the number of fixed-size segments acquired in single-shot mode (see the instrument specifications for the limits). The oscilloscope uses the sequence timebase setting to determine the capture duration of each segment.
GETTING STARTED MANUAL 1. Touch Timebase → Horizontal Setup on the menu bar. 2. Click the Sequence tab. 3. Under Acquisition Settings, touch inside the Number of Settings data entry field and enter the number of segments you want to display. Note: The number of segments you choose to display can be less than the total number of segments in the waveform.
WAVESURFER MXS-B OSCILLOSCOPE Zooming Segments in Sequence Mode You can zoom individual segments easily using the QUICKZOOM front panel button. When you zoom, the zoom traces default to Segment 1. Channel descriptors indicate the total number of segments acquired. Zoom descriptors indicate [Seg #] and #Segments in the Zoom. You can scroll through the segments using ZOOM front panel position knob. 1. Touch the front panel Quickzoom button. 2.
GETTING STARTED MANUAL Viewing Time Stamps You can view time stamps for each segment. To view time stamps, from the Sequence tab select Show Sequence Trigger Times.
WAVESURFER MXS-B OSCILLOSCOPE USING THE MATH TRACE Overview Math allows you to perform simple and complex mathematical calculations on your signal, or on a zoom or memory (reference waveform). The oscilloscope can be operating in any acquisition mode (Real-Time, RIS, or Roll Mode) when Math is created. Math traces are defined with an Operator and a Source. Examples of Operators include Add, Subtract, Multiply, Divide, and FFT. Sources are channels, zoom traces, or memories (reference waveforms).
GETTING STARTED MANUAL Description of math functions The WaveSurfer MXs-B oscilloscope contains several Math operators as standard, plus an FFT function. Descriptions are provided as follows: Standard Math Absolute Value – calculates the absolute value of a waveform. Average – calculates either a summed or continuous average up to 1 million sweeps (user selectable). Derivative – calculates the derivative of adjacent samples. Difference (Subtract) – subtracts two waveforms.
WAVESURFER MXS-B OSCILLOSCOPE Reciprocal – calculates the reciprocal of the waveform. Rescale – allows user-defined rescaling, including user defined units. Roof - calculates the highest vertical values of a waveform at each horizontal value for a given number of acquisitions (sweeps). Square – calculates the square of the waveform. Square Root – calculates the square root of the waveform. Sum (Add) – Adds two waveforms.
GETTING STARTED MANUAL Setting up a Math Trace 1. Press the Math front panel button Or, touch Math Math Setup… from the Menu Bar. The following dialog is shown on the lower display with the Math trace ON and the last selected Math Operator chosen as the current operator. 2.
