Back Input/Output Panel A. WaveSource connector outputs signal generated by the internal waveform generator. B. MicroSD Card slot. C. EXT Trig connector accepts external trigger. D.
WaveSurfer 3000 Oscilloscopes Analog Inputs A series of BNC connectors arranged on the front of the oscilloscope are used to input analog signal on Channels 1-4. EXT, on the back of the oscilloscope, can be used to input an external trigger pulse. 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.
Operator's Manual 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.
WaveSurfer 3000 Oscilloscopes Touch Screen The touch screen is the principal viewing and control center of the oscilloscope. The entire display area is active: use your finger or a stylus to touch, touch-and-drag, or draw a selection box. Many controls that 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 is convenient for you.
Operator's Manual Signal Display Grid The grid area displays the waveform traces. It is sectioned into 10 Horizontal (Time) divisions and 8 Vertical (Voltage) divisions. By default, the oscilloscope divides the screen into a maximum of three grids, one each for channels/memories, math functions, and zooms. All traces of the same type appear on the same grid.
WaveSurfer 3000 Oscilloscopes 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 trigger Delay values are shown on the Timebase Descriptor Box. Trigger Level - This small triangle at the right edge of the grid tracks the trigger voltage level.
Operator's Manual Channel Descriptor Box Channel trace descriptor boxes correspond to analog signal inputs. They show Vertical settings and any Vertical cursor readouts: (clockwise from top left) Trace Number (Cx), Pre-Processing List (summarizes changes from default state), Coupling, Gain Setting, Offset Setting, and Averaging Sweeps Count. Codes are used to indicate pre-processing that has been applied to the input. The codes have a long and short form.
WaveSurfer 3000 Oscilloscopes 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 setup option. For convenience, related dialogs appear as a series of tabs behind the main dialog. Touch the tab to open the dialog. Right-Hand Dialogs At times, your selections will require more settings than normally appear (or can fit) on a dialog, or the task commonly invites further action, such as zooming a new trace.
Operator's Manual Turning On/Off Traces Analog Trace From the display, choose Vertical > Channel <#> Setup to turn on the trace. To turn it off, clear the Trace On checkbox on the corresponding Channel dialog. From the front panel, press the Channel button (1-4) to turn on the trace; press again to turn it off. Digital Trace From the display, choose Vertical > Digital <#> Setup. From the front panel, press the Dig button, then check Group on the Digital<#> trace dialog. Clear Group to turn off the trace.
WaveSurfer 3000 Oscilloscopes Annotating Traces The Label function gives you the ability to add custom annotations to traces that are shown on the display. Labels are numbered sequentially in the order they were created. Once placed, labels can be moved to new positions or turned off. Create Label 1. Touch the trace and choose Set label... from the context menu, or touch the trace descriptor box twice and touch the Label toolbar button on the setup dialog. 2.
Operator's Manual Entering/Selecting Data Touch Touch once to activate a control. In some cases, you’ll immediately see a pop-up menu of options. Touch one to select it. TIP: You can touch the Icon or List buttons where they appear on larger pop-ups to change how menu options are displayed. In other cases, data entry fields appear highlighted in blue when you touch them. When a data entry field is highlighted, it is active and can be modified by using the front panel Adjust knob.
WaveSurfer 3000 Oscilloscopes Touch & Drag Touch-and-drag cursor lines and annotation labels to reposition them on the grid; this is the same as setting the values on the dialog. Touch-and-drag to draw a selection box around part of a trace to quickly zoom that portion.
Operator's Manual Print Preview The Print Preview feature allows you to pause the fast display for closer waveform inspection or printing. No function other than printing is available when in Print Preview mode. All oscilloscope analysis functions (such as measurement calculations) are also paused. There are three ways to invoke Print Preview: l l l On the Utilities > Utilities Setup > Hardcopy dialog, check the box labeled Preview on Print.
WaveSurfer 3000 Oscilloscopes Printing/Screen Capture The Print function captures an image of the display and outputs it according to your Hardcopy settings. There are three ways to print a capture of the screen: l Touch the front panel Print button. l Choose File > Print. l Choose Utilities > Utilities Setup > Hardcopy tab and touch the Print button to the far right of the dialog.
Operator's Manual Front Panel Most front panel controls duplicate functionality available through the touch screen display and are described on the following pages. All the knobs on the front panel function one way if turned and another if pushed like a button. The top label describes the knob’s “turn” action, the bottom label its “push” action. Front panel buttons light up to indicate which traces and functions are active. Actions performed from the front panel always apply to the active trace.
WaveSurfer 3000 Oscilloscopes Horizontal Controls The Delay knob changes the Trigger Delay value (S) when turned. Push the knob to reset Delay to zero. The Horizontal Adjust knob sets the Time/division (S) of the oscilloscope 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 oscilloscope allocates memory as needed to maintain the highest sample rate possible for the timebase setting.
Operator's Manual Adjust and Intensity Controls The Adjust knob changes the value in any highlighted data entry field when turned. Pushing the Adjust knob toggles between coarse (large increment) or fine (small increment) adjustments when the knob is turned. When more data is available than can actually be displayed, the Intensity button helps to visualize significant events by applying an algorithm that dims less frequently occurring samples.
WaveSurfer 3000 Oscilloscopes Zooming Waveforms The Zoom function magnifies a selected region of a trace. On WaveSurfer 3000 model oscilloscopes, you can display up to four zoom traces (Z1-Z4) taken from any channel, math, or memory trace. Creating Zooms To create a zoom, touch -and-drag to draw a selection box around any part of the source waveform. Selection box over trace. The zoom will resize the selected portion to fit the full width of the grid.
Operator's Manual and memory traces). Turn off Zoom To close the zoom, either touch the zoom descriptor box twice to open the Zoom dialog and deselect Trace On, or touch the zoom trace to open the context menu and choose Off. Zoom Controls To open the Zoom dialog, touch twice on any zoom descriptor box, or choose Math > Zoom Setup from the menu bar. Trace Controls Trace On shows/hides the zoom trace. It is selected by default when the zoom is created.
WaveSurfer 3000 Oscilloscopes Vertical Vertical, also called Channel, settings usually relate to voltage level and control the trace along the Y axis. NOTE: While Digital settings can be accessed through the Vertical menu on oscilloscopes with the Mixed Signal option, they are handled quite differently. See Digital. The amount of voltage displayed by one vertical division of the grid, or Vertical Scale (V/div), is most quickly adjusted by using the front panel Vertical knob.
Operator's Manual Probe Settings When a Teledyne LeCroy-compatible probe is connected to the oscilloscope input, the probe is automatically identified and the model name displayed on the Channel dialog under the "Probe" heading. Also, the Probe dialog bearing the probe name is added to the right of the Channel dialog. When a probe is not connected, the Channel dialog shows only the Cx tab for vertical setup.
WaveSurfer 3000 Oscilloscopes DeGauss Probe The Degauss control is activated for some types of probes (e.g., current probes). Degaussing eliminates residual magnetization from the probe core caused by external magnetic fields or by excessive input. It is recommended to always degauss probes prior to taking a measurement. CAUTION. Remove the probe from the circuit under test before initializing DeGauss.
Operator's Manual Viewing Status All oscilloscope settings can be viewed through the various Status dialogs. These show all existing acquisition, trigger, channel, math function, measurement and parameter configurations, as well as which are currently active. Access the Status dialogs by choosing the Status option from the Vertical, Timebase, Trigger, or Math menus (e.g., Channel Status, Acquisition Status).
WaveSurfer 3000 Oscilloscopes Digital (Mixed Signal) The digital leadset (delivered with the WS3K-MSO option) inputs up-to-16 lines of digital data. Leads are organized into two banks of eight leads each, and you assign each bank a standard Logic Family or a custom Threshold to define the digital logic of the signal. The Digital set up dialog has two tabs each corresponding to one of two possible digital groups, labeled Digital1 to Digital2, which correspond to buses.
Operator's Manual 2. On the Digital<#> set up dialog, check the boxes for lines D0 through D15 that comprise the group. Touch the Display D0-D7 and Display D8-D15 buttons to quickly turn on the entire digital bank, or touch the Right and Left Arrow buttons to switch between each digital bank as you make line selections. NOTE: Each group can consist of anywhere from 1 to 16 of the leads that are (or will be) connected to signal, from either digital bank regardless of the Logic set on the bank.
WaveSurfer 3000 Oscilloscopes Individual traces are resized to fit the total number of divisions available. The example above shows a group of three Line traces plus the Bus trace occupying a Group Height of 4.0 divisions. Each trace takes up one division. 5. Check the Group box to enable the display. To close traces, uncheck the Group box. Renaming Digital Lines The labels used to name each line can be changed to make the user interface more intuitive. Also, labels can be "swapped" between lines.
Operator's Manual Timebase Timebase, also known as Horizontal, settings control the trace 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, including sampling mode selection, is done on the Timebase dialog, which can be accessed by either choosing Timebase > Horizontal Setup from the menu bar, or touching the Timebase descriptor box.
WaveSurfer 3000 Oscilloscopes Sampling Modes Real Time Sampling Mode Real Time sampling mode is a series of digitized voltage values sampled on the input signal at a uniform rate. These samples are displayed as a series of measured data values associated with a single trigger event. By default, the waveform is horizontally positioned so that the trigger event is time zero on the grid.
Operator's Manual SET UP SEQUENCE MODE 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. Along with this setting, the oscilloscope uses the number of segments, maximum segment length, and total available memory to determine the actual number of samples or segments, and time or points. 1.
WaveSurfer 3000 Oscilloscopes Use the Zoom controls to change the scale factors of the trace. Roll Mode Roll mode displays, in real time, incoming points in single-shot acquisitions that appear to "roll" continuously across the screen from right to left 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.
Operator's Manual Average Sampling Mode Average sampling mode calculates the average value for each captured point over a specified number of acquisitions (2, 4, 8, 16, 32, 64, 128, 256, 512, and 1024 sweeps are all available). Each individual acquisition uses Real Time mode and the results are averaged together. Average mode can be used to reduce random noise in repeating signals. When selecting Average sampling mode, also select the number of Sweeps to calculate in the Average.
WaveSurfer 3000 Oscilloscopes History Mode History Mode allows you to review any acquisition saved in the oscilloscope's 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 individual details or changes in the waveforms over time.
Operator's Manual l l The top row of buttons scrolls continuously and are (left to right): Fast Backward, Slow Backward, Pause, Slow Forward, Fast Forward. The bottom row of buttons steps one record at a time and are (left to right): Back to Start, Back One, Go to Index (#), Forward One, Forward to End. 5. Entering History Mode automatically stops new acquisitions. To leave History Mode, press the History Mode button again, or restart acquisition by pressing one of the front panel Trigger Mode buttons.
WaveSurfer 3000 Oscilloscopes Trigger While the oscilloscope is continuously sampling signal when it is turned on, it can only display up to its maximum memory in data samples. Triggers select an exact event/time in the waveform to display on the oscilloscope screen so that memory is not wasted on insignificant periods of the signal.
Operator's Manual Trigger Types These are the trigger types available for selection. If the trigger is part of a subgroup (e.g., Smart), first choose the subgroup from among the basic types to display all the trigger options. Basic Triggers 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.
WaveSurfer 3000 Oscilloscopes SlewRate triggers when the rising or falling edge of a pulse crosses an upper and a lower level. The pulse edge must cross the thresholds faster or slower than a selected period of time. Serial Triggers The Serial trigger type will appear if you have installed protocol-specific serial data trigger and decode options. Select this type to open the serial trigger setup dialogs. Instructions for using all serial data options are available from our website at teledynelecroy.

WaveSurfer 3000 Oscilloscopes Qualified Trigger Qualified arms the trigger on the A event, then fires on the B event. In Normal trigger mode, it automatically resets after the B event. The options for the B event depend on the type of A event. You may apply additional Holdoff by time or number of events. On the Trigger dialog, select Qualified trigger type to display the controls. Besides an Edge level, the arming ("A") event may be a State, any voltage measured above or below a threshold Level.
Operator's Manual Pattern Trigger Pattern is the default trigger when the digital leadset is connected to the oscilloscope, as these users generally wish to find and trigger upon digital logic patterns. However, a Pattern trigger can also be set on a user-defined pattern of High or Low voltage levels in analog channels (including the External Trigger input), or a combination of digital and analog patterns when Mixed Signal capabilities are available. On the Trigger dialog, select Pattern trigger type.
WaveSurfer 3000 Oscilloscopes 3. If you have not already set a logic threshold, open the Levels dialog and select a Logic Family for each digital bank from which you've selected lines. To set a custom logic threshold, choose Logic Family User Defined, then enter the Threshold voltage and Hysteresis. NOTE: Digital lines inherit the Logic Setup made when defining digital groups. However, you can change the logic threshold on the Levels dialog, as well.
Operator's Manual Standard Dialogs The standard dialog for setting up an analog Pattern trigger includes all the controls for setting the pattern and the voltage threshold on the same dialog. 1. Select the Boolean Operator (AND, NAND, OR, or NOR) that describes the relationship among analog inputs (e.g., C1 must be High NAND C2 must be Low). 2. For each input to be included in the trigger pattern, and select what State it must be in (High, Low, or Don't Care) compared to the threshold Level you will set.

Choose the Source input. 2. Choose the type of signal Coupling at the input.
WaveSurfer 3000 Oscilloscopes Trigger Holdoff Holdoff is an additional condition that may be set for Edge and Pattern triggers. It can be expressed either as a period of time or an event count. Holdoff disables the trigger temporarily, even if the trigger conditions are met, until the holdoff conditions are also met. The trigger fires when the holdoff has elapsed. Use holdoff to obtain a stable trigger for repetitive, composite waveforms.
Operator's Manual In the figure below, the bold edges on the trigger source indicate that a positive slope has been selected. The broken, upward-pointing arrows indicate potential triggers, while the bold ones show where triggers actually occur after the holdoff expires. Edge trigger with holdoff by events. Holdoff Settings To access the Trigger Holdoff dialog, choose Triggers > Trigger Setup from the menu bar or press the front panel Trigger Setup button, then touch the Holdoff tab.
WaveSurfer 3000 Oscilloscopes Display Display settings affect the number and style of grids that appear on screen and some of the visual characteristics of traces, such as persistence. Display Settings To access the Display dialogs, choose Display > Display Setup or Display > Persistence Setup. Grid Select one of the grid types: Auto, the default, automatically adds or deletes grids as you open or close traces, up to the maximum number supported. Single displays a single grid shared by all traces.
Operator's Manual Persistence The Persistence feature retains waveform traces on the display for a set amount of time before allowing them to gradually "decay," similar to the display of old phosphor screen oscilloscopes. Use Persistence to accumulate on-screen points from many acquisitions to see your signal change over time. The persistence modes show the most frequent signal path in three-dimensional intensities of the same color (Analog), or graded in a spectrum of colors (Color).
WaveSurfer 3000 Oscilloscopes Other Persistence Settings Besides the different modes, you can select a Saturation level as a percentage of the maximum population. All populations above the saturation population are then assigned the highest color intensity: that is, they are saturated. At the same time, all populations below the saturation level are assigned the remaining intensities. Data populations are dynamically updated as data from new acquisitions is accumulated.
Operator's Manual Cursors Cursors are markers (lines or cross-hairs) that identify specific voltage and time values on the waveform. Use cursors to make fast, accurate measurements of specific points in the waveform. There are three, standard cursor types available. Vertical (amplitude) cursor readouts appear the descriptor box for the trace; Horizontal (time) cursor readouts appear below the Timbebase descriptor box. Horizontal and vertical cursors.
WaveSurfer 3000 Oscilloscopes Cursor Settings Display Cursors To quickly turn on/off cursors, either: l l From the menu bar, choose Cursors then select the desired cursor type from the drop-down list. On the front panel, press the Cursor Type button repeatedly to cycle through all the cursor types. Stop when the desired type is displayed. Position Cursors Te easiest way to position a cursor is to touch and drag the cursor line to a new position.
Operator's Manual Measure Measurement parameters are tools that give you access to a wide range of waveform properties. Use them to analyze many attributes of your waveform such as rise-time, rms voltage, and peak-to-peak voltage. You can create a custom set of up to six parameters drawn from all the standard measurements, as well as specialized measurements installed with optional software packages. Measurement readouts appear in a table below the grid. Readouts can be individually turned on/off.
WaveSurfer 3000 Oscilloscopes 5. Optionally, set a measurement gate by entering the Gate Start and Stop divisions or dragging the gate posts from the far left and right edges of the grid to reposition them. 6. Choose to display Statistics or Histicons on the measurement readout table. Gating Measurements By using gates, you can narrow the span of the waveform on which to perform parameter measurements, allowing you to focus on the area of greatest interest.
Operator's Manual List of Standard Measurement Parameters NOTE: There may be additional parameters available depending on the software options installed on the oscilloscope. Parameter Description Amplitude (ampl) Measures the difference between upper and lower levels in two-level signals. Differs from pkpk in that noise, overshoot, undershoot, and ringing do not affect the measurement. Amplitude is calculated by using the formula Top – Base.
WaveSurfer 3000 Oscilloscopes Parameter Description period is measured for each transition pair, with values averaged to give final result. Phase Phase difference between signal analyzed and signal used as reference. Both signals are measured from the 50% point of their rising edges. Rise 20-80% (rise2080) Duration of pulse waveform's rising transition from 20% to 80% of the amplitude averaged for all rising transitions between the measurement gates.
Operator's Manual Calculating Measurements Determining Top and Base Lines Proper determination of the top and base reference lines is fundamental for ensuring correct parameter calculations. The analysis begins by computing a histogram of the waveform data over the time interval spanned by the left and right measurement gates. For example, the histogram of a waveform transitioning in two states will contain two peaks (see figure).
WaveSurfer 3000 Oscilloscopes Where Mr is the number of leading edges found, Mf the number of trailing edges found, rising edge i crosses the x% level, the time when and the time when falling edge i crosses the x% level. Determining Time Parameters Time parameter measurements such as width, period and delay are carried out with respect to the mesial reference level, located halfway (50%) between the top and base reference lines.
Operator's Manual Math Math traces (F1-F2)) display the result of applying a mathematical operation to a source trace. The output of a math function is always another trace, whereas the output of a measurement parameter is a tabular readout of the measurement. Math can be applied to any channel (Cx), zoom (Zx), or memory (Mx) trace.
WaveSurfer 3000 Oscilloscopes 5. If the operator you've selected has any other configurable settings, you'll see a right-hand dialog of the same name as the operator. Touch the tab to open the dialog and make any further settings. These are explained on the dialog. There will also be a Zoom dialog where you can optionally adjust the math trace. This does not affect the scale of any other traces.
Operator's Manual List of Standard Math Functions NOTE: Additional math functions may be available depending on the options installed on the oscilloscope. Function Definition Absolute For every point in the waveform the distance away from zero is calculated. For values greater than zero this is the same as the value. For values less than zero, the magnitude of this value without regard to its sign is used. Average Calculates either a summed or continuous average of a selected number of sweeps.
WaveSurfer 3000 Oscilloscopes Function Definition Trend Produces a waveform composed of a series of parameter measurements in the order the measurements were taken. The vertical units are those of the source parameter, the horizontal unit is measurement number. The trend contains a single value for each measurement. Zoom Zoom of input source. Trend A trend is a waveform composed of a series of parameter measurements in the order the measurements were taken.
Operator's Manual Rescaling and Assigning Units The rescale function allows you to apply a multiplication factor (a) and additive constant (b) to your waveform: aX + b.

Operator's Manual Averaging Waveforms Summed Averaging Summed Averaging is the repeated addition, with equal weight, of successive source waveform records. If a stable trigger is available, the resulting average has a random noise component lower than that of a singleshot record. Whenever the maximum number of sweeps is reached, the averaging process stops. In Summed averaging, you specify the number of acquisitions to be averaged. The averaged data is updated at regular intervals.
WaveSurfer 3000 Oscilloscopes 6th sweep: new average = (new data + 4 * old average)/(4 + 1) = 1/5 new data + 4/5 old average 7th sweep: new average = (new data + 4 * old average)/(4 + 1) = 1/5 new data + 4/5 old average In this way, for sweeps > 4 the importance of the old average begins to decrease exponentially. NOTE: The number of sweeps used to compute the average is displayed at the bottom of the trace descriptor box.
Operator's Manual 3. Choose an Output type. 4. Optionally, choose a weighting Window. See below for more information about FFT weighting windows. 5. Depending on your Output Type selection, you may also make selections for : l l Group Delay Shift Line Impedence. By default, the FFT function assumes that the oscilloscope is terminated in 50 Ohms. If an external terminator is being used, this setting can be changed to properly calculate the FFT based on the new termination value. 6.
WaveSurfer 3000 Oscilloscopes Window Type Applications and Limitations Rectangular These are normally used when the signal is transient (completely contained in the time-domain window) or known to have a fundamental frequency component that is an integer multiple of the fundamental frequency of the window. Signals other than these types will show varying amounts of spectral leakage and scallop loss, which can be corrected by selecting another type of window.
Operator's Manual Memory The oscilloscope is equipped with twointernal memory slots (Mx) to which you can copy any channel, math, zoom or other special waveform that is active on the grid. This is a convenient way to store an acquisition for later viewing and analysis. Memories are created at the same scale as the source trace, but they can be adjusted independent of the original by using the Zoom controls that appear next to the Mx dialogs. Save Waveform to Memory 1.
WaveSurfer 3000 Oscilloscopes Analysis Most Teledyne LeCroy oscilloscopes calculate measurements for all instances in the acquisition, enabling you to rapidly and thoroughly analyze a long memory acquisition of thousands or millions of parameter values, or to apply a variety of mathematical functions to the waveform trace.
