With the oscilloscopes synchronized, use a splitter to input one half of a repetitive signal (e.g., sine or square wave) to any of the Main channels and the other half to any of the Remote channels.

  • Page 22: Using Maui

    Windows touch screen features. MAUI Application MAUI forms the front-end of Teledyne LeCroy oscilloscopes, providing a single interface for all standard and optional oscilloscope applications. MAUI runs on the Microsoft Windows platform. The oscilloscope firmware and standard applications are active upon delivery. At power-up, the instrument loads the software automatically.

  • Page 23: Touch Screen

    Using MAUI Touch Screen With MAUI, the touch screen is the principal control center of the oscilloscope. The entire display is active: use your finger or a stylus to touch, drag, swipe, and draw selection boxes. With the addition of OneTouch, gestures such as pinch and flick can be used to control the screen.
  • Page 24 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Grid The grid displays the waveform traces. Every grid is 8 Vertical divisions representing the full number of 4096 Vertical levels and 10 Horizontal divisions representing the total acquisition time. The value of each division depends on the Vertical and Horizontal scale of the traces that appear on that grid.
  • Page 25 Using MAUI Pre/Post-trigger Delay , a small arrow to the bottom left or right of the grid, indicates that a pre- or post- trigger 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.
  • Page 26 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Processing Type Code Deskew Noise Filter (ERes) Inversion Note: When (Sinx)/x interpolation is applied automatically by the Enhanced Sample Rate feature, the Cn descriptor box will show ESR. When applied manually, descriptors will show SINX. Note: Interpolation, Averaging and Noise Filter are disabled on acquisitions >500 Mpts in length.
  • Page 27 Using MAUI 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.
  • Page 28 At the bottom of the oscilloscope display is a narrow message bar. The current date and time are shown at the far right. Status, error, or other messages are shown at the far left, where "Teledyne 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.

  • Page 29: Controlling Traces

    Using MAUI Controlling Traces Traces are the visible representations of waveforms that appear on the display grid. They may show live inputs (Cn, Digitaln), a math function applied to a waveform (Fn), a stored memory of a waveform (Mn), a zoom of a waveform (Zn), or the processing results of special analysis software.
  • Page 30 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Activating Traces Although several traces may be open, only one trace is active and can be adjusted using front panel controls and touch screen gestures. A highlighted descriptor box indicates which trace is active. All actions apply to that trace until you activate another.
  • Page 31 Using MAUI Moving Traces You can move a trace from one grid to another by dragging its descriptor box to the desired grid. This is a convenient way to quickly re-arrange traces on the display. If you are in Q-Scape display mode, you can drag the descriptor box to a grid on another tab, provided the grid is visible while you are moving the trace.
  • Page 32 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Labeling Traces The Label function gives you the ability to add custom annotations to the trace display. Once placed, labels can be moved to new positions or hidden while remaining associated with the trace. Create Label 1.
  • Page 33 Using MAUI Finding Trace Status If a small letter "i" inside a bubble appears on the trace descriptor box, this indicates there is additional information regarding a waveform processing error that resulted in the oscilloscope being unable to display a trace, or producing a trace that could lead to unreliable measurements.

  • Page 34: Maui With Onetouch

    WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual MAUI with OneTouch Gestures like 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 dialogs to refine OneTouch actions to precise values.
  • Page 35 Using MAUI Copy Setups To copy the setup of one trace to another of the same type (e.g., channel to channel, math to math), drag-and-drop the source descriptor box onto the target descriptor box. To copy the setup of a measurement (Pn), drag-and-drop the source column onto the target column of the Measure table.
  • Page 36 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Position Cursors To change cursor measurement time/level, drag cursor markers to new positions on the grid. The cursor readout will update immediately. To place horizontal cursors on zooms or other calculated traces where the source Horizontal Scale has forced cursors off the grid, drag the cursor readout from below the Timebase descriptor to the grid where you wish to place the cursors.
  • Page 37 Using MAUI Store to Memory To store a trace to internal memory, drag-and-drop its descriptor onto the target memory (Mn) descriptor. Move Trace To move a trace to a different grid, drag-and-drop the trace descriptor box onto the target grid. If you are in a multi- tabbed Q-Scape display mode, you can move traces between tabs this way.
  • Page 38 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Tip: If you are using the multi-zoom feature, all time-locked traces will pan together. Panning is an excellent way to quickly move a trace into the Analysis Zone on >500 Mpts acquisitions. To pan at an accelerated rate, swipe the trace right/left or up/down.
  • Page 39 Using MAUI Pinch Zoom To "zoom in" on any trace, unpinch two fingers over the trace horizontally. To "zoom out" on any trace, pinch two fingers over the trace horizontally. Note: Pinch gestures do not create a separate zoom (Zn) trace, they only adjust the Horizontal Scale. When you pinch a channel (Cn) trace, the Timebase for all channels changes.

  • Page 40: Waveform Acquisition

    WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Waveform Acquisition Topics in this section explain how to configure the instrument to acquire and view the status of waveforms. Auto Setup Auto Setup configures the essential acquisition settings based on the first input signal it finds, starting with C1. If nothing is connected to C1, it searches C2 and so forth until it finds a signal.
  • Page 41 Full vertical setup is done on the individual Cn dialogs. To access them, choose Vertical > Channeln Setup from the menu bar, or touch the Channel descriptor box. If a Teledyne LeCroy probe is connected, its Probe dialog appears to the right of the Cn dialog.
  • Page 42 Probe Attenuation values for third-party probes may be entered manually on the Cn dialog. The instrument will detect it is a third-party probe and display these fields. When a Teledyne LeCroy probe is connected to a channel input, the Attenuation field becomes a button to access Probe dialog, a tab added to the right of the Cn tab.
  • Page 43 Waveform Acquisition Cable De-Embedding Option Losses in the cables used in the test setup can reduce the accuracy of your signal (e.g., signal amplitude and rise time), as well as introduce Inter-Symbol Interference. These cable effects can dramatically alter measurements and potentially create mask test violations.
  • Page 44 Auto Zero corrects for DC offset drifts that naturally occur from thermal effects in the amplifier of active probes. Teledyne LeCroy probes incorporate Auto Zero capability to remove the DC offset from the probe's amplifier output to improve the measurement accuracy.

  • Page 45: Digital (Mixed-Signal)

    Waveform Acquisition Digital (Mixed-Signal) When a mixed-signal device is connected to the oscilloscope, digital input setup options are added to the Vertical menu. There are set up dialogs for digital groups Digital1 to Digital4, which correspond to possible digital buses. You: Choose which lines make up each digital group, what they are named and how they appear on the display...
  • Page 46 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Digital Group Set Up Digital Group dialog when using Digital Leadset (MSO). A group defines the lines that comprise a bus or that you wish to view together. To set up a digital group: 1. From the menu bar, choose Vertical > Digitaln Setup. 2.
  • Page 47 Waveform Acquisition In Vertical Position, enter the number of divisions (positive or negative) relative to the zero line of the grid where the display begins.The top of the first trace appears at this position. In Group Height, enter the total number of grid divisions the entire display should occupy. All the selected traces (Line and Bus) will appear in this space.
  • Page 48 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Shortcut Buttons At the right side of the Digitaln dialogs are buttons to: Create a new Zoom of a Digital group display. Each press of the button zooms each group displayed in order, creating Z1 for Digital1, then Z4 for Digital4, etc. The zoom's horizontal and vertical scale can be changed from that of the original digital group display to show transitions in more detail.
  • Page 49 Waveform Acquisition Digital Pattern Trigger Pattern is the default trigger type selection when a digital input device is connected to the instrument. A Pattern trigger can be set on a digital logic pattern, or a combination of digital logic and analog states. Logic Bus Method The Logic Bus method simplifies pattern set up by utilizing digital groups and logic you have already defined on the Digital setup dialogs.

  • Page 51: Timebase

    Waveform Acquisition Timebase Timebase (Horizontal) settings control traces along the X axis. The timebase is shared by all channels. The time represented by each horizontal division of the grid, or Time/Division, is most easily adjusted using the front panel Horizontal knob. Full Timebase set up is done on the Timebase dialog, accessed either by choosing Timebase >...
  • Page 52 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Sequence Sampling Mode In Sequence Mode sampling, the completed acquisition consists of a number of fixed-size segments each containing the trigger event. The instrument calculates the capture duration and number of sample points in each segment from the user-defined number of segments and total available memory.
  • Page 53 Waveform Acquisition Fixed Sampling Rate allows you to set a fixed rate of sampling, in which case the length of acquisition depends on the Time/div. The oscilloscope will use whatever memory is required for the acquisition time, until none remains. Lowering the rate can extend the acquisition to accommodate slower timebases or longer delays.
  • Page 54 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Example: On WaveRunner 8000HD, selecting 4 Active Channels turns off acquisition on C1, C4, C5 and C8, while C2, C3, C6 and C7 acquire at double the per channel acquisition memory. On 8-channel oscilloscopes with two banks of four channels (C1-C4 and C5-C8), a similar interleaving of outer and inner pairs occurs when 2 Active Channels is selected, leaving C3 and C6 active at the maximum possible memory.
  • Page 55 Waveform Acquisition Adjacent Overlay Perspective Waterfall (cascaded) Mosaic (tiled) 5. To see the trigger times of those segments acquired, stop acquisition and touch Show Sequence Trigger Times. This will launch the Trigger Time tab of the Acquisition Status dialogs. When in Sequence sampling mode, you can view individual segments easily using the front panel Zoom button. A new zoom of the channel trace defaults to Segment 1.
  • Page 56 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Navigating Long Acquisitions On acquisitions >500 Mpts in length, measurements and math calculations take place on only the center 500 Mpts of the acquisition—the "Analysis Zone". This area is marked on the source channel trace by grey shading applied outside of it (over the part not analyzed).
  • Page 57 Waveform Acquisition Navigating with Zoom Stop acquisition, then create a zoom trace of the area you wish to analyze. Apply math and measurements to the zoom rather than the channel trace. Math applied to a zoom is calculated on the entire trace (up to 500 Mpts). Highlighting shows the area analyzed. Navigation Reference Changing the Navigation Reference setting can also help to reposition the trace for analysis by selecting for different regions of the acquisition to remain centered as the Time/div changes.
  • Page 58 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Lock to Trigger rescales divisions around the trigger point. The trigger remains in place as Time/div changes, while other events move in reference to the trigger. If the trigger is currently at time zero, this appears to behave the same as Centered, but the difference will be apparent if you have used Delay to shift the trigger position.
  • Page 59 Waveform Acquisition History Mode History Mode allows you to review any acquisition saved in the history buffer, which automatically stores all acquisition records until full. Not only can individual acquisitions be restored to the grid, you can "scroll" backward and forward through the history at varying speeds to capture changes in the waveforms over time. To access this feature, choose Timebase >...

  • Page 60: Trigger

    WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Trigger Triggers define the event around which digitized information is displayed on the grid. Different Trigger Types are used to select different events in the trigger source waveforms: edge voltages, pulse widths, high/low states, etc. These may be a single channel event or a complex pattern of events across several channels.
  • Page 61 Waveform Acquisition Trigger Types The Trigger Type sets the triggering conditions. Edge triggers upon a achieving a certain voltage level in the positive or negative slope of the waveform. Width triggers upon finding a positive- or negative-going pulse width when measured at the specified voltage level. Pattern triggers upon a user-defined pattern of high and low voltage levels on selected inputs.
  • Page 62 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual the oscilloscope's Ext. In port. In Pattern triggers, the Ext. In port may be examined for a High/Low state as part of the overall triggering pattern. Select the Coupling to use for the Ext. In port when defining the pattern. "Line triggers"...
  • Page 63 Waveform Acquisition Level For analog triggers, enter the Level at which the triggering condition must occur. Use the Find Level button to set the level to the signal mean. Trigger types that require multiple crossings to define the triggering condition—such as Window, SlewRate and Runt—...
  • Page 64 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Patterns A triggering logic pattern may be set on digital lines, analog channels or a combination of both. See Digital Pattern Trigger for digital/mixed-signal trigger setup instructions. Purely analog patterns may be set on a combination of High/Low states across the channels and the External input. Disconnect any digital input device to enable the analog pattern trigger controls.
  • Page 65 Waveform Acquisition Measurement Trigger Measurement is not technically a trigger, but permits the instrument to stop and display acquisition based on a post- processing measurement result, similar to a trigger. The available measurements will each offer a different method for specifying the "trigger" conditions, based on the type of measurement. Generally, you will be able to specify a triggering value or range of values, and for @level parameters, the voltage level at which the measurement is taken.
  • Page 66 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Qualified Trigger A Qualified trigger arms when the qualifying A event occurs on one signal, then fires when the B event occurs on another signal. In Normal trigger mode, it automatically resets after the B event and re-arms upon the next qualifying A event.
  • Page 67 Waveform Acquisition Time Window When the B event is the occurrence of an Edge or Pattern, a window can be set to constrain the time in which B must occur following A in order for the trigger to fire. Use the When B Occurs buttons to trigger: Any Time that B occurs after being qualified by A.
  • Page 68 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Trigger Holdoff Holdoff is either a period of time or an event count that may be set as an additional condition for Edge and Pattern triggers. Holdoff disables the trigger temporarily, even if the other conditions are met. Use Holdoff to obtain a stable trigger for repetitive, composite waveforms.
  • Page 69 Waveform Acquisition Hold Off by Events Events refers to the number of times the trigger conditions have been met following the arming event. For example, if the Holdoff is two edges counted from the start of the acquisition, the oscilloscope readies, arms on the first edge, holds off for the next two, triggers on the fourth edge, then completes the acquisition.
  • Page 70 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Software Assisted Trigger Software Assisted Trigger is used to find the trigger-level crossing point closest to the hardware trigger point. It then adjusts the time offset of the waveform so that it is aligned with the specified trigger level and slope. In the following figure, the white trace is the waveform at the input to software-assisted trigger processing.
  • Page 71 Waveform Acquisition TriggerScan TriggerScan is a debugging tool that helps you quickly discover waveform anomalies by automating the process of building triggers designed to find rare events in an acquisition. Triggerscan trains the system by looking at acquired waveforms. During the training, TriggerScan analyzes the waveforms to determine what waveforms normally look like.

  • Page 73: Display

    Display Display Display menu settings affect the number and style of grids that appear on screen and some of the visual characteristics of traces, such as persistence. The oscilloscope features a multi-grid display, where each separate grid represents the full number of 4096 vertical levels.
  • Page 74 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Note: Additional grid modes may become available with the installation of software options. Other Grid Settings To dim or brighten the background grid lines, touch Grid Intensity and enter a value from 0 to 100. Grid on top superimposes the grid over the waveform.

  • Page 75: Q-Scape Display

    Display Q-Scape Display Q-Scape divides the screen into multi-tab displays that can each be configured with different multi-grid display modes. Many of the same functions you can perform in Normal mode, such as moving traces by drag-and-drop, you can also perform in Q-Scape. Q-Scape oscilloscopes have an option for both the Display Mode and the Grid Mode. Display Mode The Display Mode setting determines the number and layout of display tabs, each of which can in turn have different numbers and styles of grids within them.
  • Page 76 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Note: If you switch from Normal mode into any Q-Scape mode, all traces will move to Tab 1, from which you can drag-and-drop to redistribute them to other grids. In Q-Scape Single mode, you will not be able to drag- and-drop traces across tabs, only to other Tab1 grids.

  • Page 77: Persistence Display

    Display Persistence Display The Persistence feature retains waveform traces on the display for a set amount of time before allowing them to gradually "decay," similar to the analog-style display of old, phosphor screen oscilloscopes. The display is generated by repeated sampling of events over time and the accumulation of the sampled data into "persistence maps". Statistical integrity is preserved because the duration (decay) is proportional to the persistence population for each amplitude or time combination in the data.
  • Page 78 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual In shaded (projected light) quality, the shape of the pulses is emphasized. This quality is monochrome only. In wire frame quality, lines of equal intensity are used to construct the persistence map. This display can be either color or Monochrome. In 3d mode, X Axis Rotation and Y Axis Roation can range 180°...

  • Page 79: Math And Measure

    Math and Measure Math and Measure Teledyne LeCroy offers a rich set of standard, pre-programmed tools for the "quickest time to insight" into the characteristics of acquired waveforms. Most instruments calculate measurements on all samples in an acquisition, enabling you to rapidly accumulate thousands or millions of parameter values. You can also apply a variety of mathematical functions to the input waveform trace and view the transformation in a math trace.
  • Page 80 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Quick Zoom Use the front panel Zoom button to quickly create one zoom trace for each displayed channel trace. Quick zooms are created at the same vertical scale as the source trace and 10:1 horizontal magnification. The MultiZoom feature is turned on, and all the new zooms are automatically added to the MultiZoom group.
  • Page 81 Math and Measure Zoom Dialog Choosing Math > Zoom Setup from the menu bar opens a dialog summarizing all active and inactive zoom trace settings. Use the selection boxes to turn on/off zooms. There are also options to: Reset All, return all zooms to x1 magnification. Quick Zoom, create a corresponding zoom trace for each open channel trace, same as using the front panel Zoom button.
  • Page 82 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual MultiZoom MultiZoom unifies the Horizontal Scale (Time/div) setting of those traces that you add to the MultiZoom group. The traces can be zooms or other types of calculated (as opposed to acquired) time traces, such as memories or math functions.

  • Page 83: Cursors

    Math and Measure Scroll Waveforms The Auto-Scroll controls appear at the right of the MultiZoom dialog. They work similarly to A/V controls to allow you to continuously scroll all the selected traces in time-locked steps from the beginning to the end of the acquisition. Cursors Cursors are markers (lines, cross-hairs, and arrows) that identify horizontal and vertical values where they intersect the X or Y axis.
  • Page 84 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Absolute shows the vertical values where X1 and X2 intersect the source trace. Delta shows the difference in vertical value where each cursor intersects the source trace (marked by the arrows), calculated as: y@X2 – y@X1 = ∆y. When the X1 arrow is higher than the X2 arrow, this will be a negative number, as it represents a drop (e.g., in voltage), even when X2 is positioned above the zero level.
  • Page 85 Math and Measure Apply and Position Cursors To turn on cursors, either: From the menu bar, choose Cursors and select the desired cursor type from the drop-down list. On the front panel, press the Cursor button to turn on cursors, then continue pressing to cycle through all the cursor types.
  • Page 86 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Standard Cursors Dialog These controls can be used instead of the front panel controls to turn on cursors or to refine the cursor position. Access the dialog by choosing Cursors > Cursors Setup from the menu bar. Cursor Type buttons select the type of cursor displayed on the grid.

  • Page 87: Measure

    Math and Measure Measure Parameters are tools that give you access to a wide range of waveform properties, such as Rise Time, RMS voltage and Peak-Peak voltage. The instrument offers a quick selection of standard parameters, or you can create a user- defined set of parameters (My Measure) drawn from all available measurements.
  • Page 88 WaveRunner/MDA 8000HD Oscilloscopes Operator's Manual Standard Parameter Sets The pre-configured standard parameter sets available on the Measure dialog are: Std Vertical: Pk-Pk, Ampl, Max, Min, Sdev, Mean, Base, Top Std Horizontal: Rise, Fall, Period, Frequency, Width, Duty Cycle, Delay, N Points To quickly begin a new set of user-defined parameters based on the standard vertical or horizontal sets, touch Quick Setups and choose the set to copy.
  • Page 89 Math and Measure Gates (vertical white lines) limit the data measured and visibly change measurement calculations. If you wish to gate all parameters to the same number of edges, use the Gate fields on the Measure dialog. For user- defined parameter sets ("My Measure"), first check Lock to activate the Start and Stop fields. Standard parameter sets are automatically gated to the same number of edges, you do not need to first Lock the gates.
