  • Page 44: Sampling Modes

    WaveSurfer 3000/3000z Oscilloscopes Operator's Manual Memory Maximum Points is the maximum number of samples taken per acquisition. The actual number of samples acquired can be lower due to the current Sample Rate and Time/Division settings. The oscilloscope will allot the maximum memory and sample rate possible based on the activity within each pair of channels.
  • Page 45 Acquisition RIS Sampling Mode RIS (Random Interleaved Sampling) allows effective sampling rates higher than the maximum single-shot sampling rate. It is available on timebases ≤ 10 ns/div. The maximum effective RIS sampling rate is achieved by making multiple single-shot acquisitions at maximum real-time sample rate.
  • Page 46 WaveSurfer 3000/3000z Oscilloscopes Operator's Manual Sequence Mode Set Up The Sequence dialog appears only when Sequence Mode sampling is selected. Use it to define the number of fixed-size segments to be acquired. 1. From the menu bar, choose Timebase > Horizontal Setup..., then Sequence Sampling Mode.
  • Page 47 Acquisition Viewing Sequence Segments 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. You can view other segments by changing the First and total Num(ber) of segments to be shown on the Zn dialog.

  • Page 48: History Mode

    WaveSurfer 3000/3000z Oscilloscopes Operator's Manual Set Reference Clock By default, the oscilloscope is set to use its internal clock of 10 MHz as the Timebase reference to synchronize acquisition across all channels. You can opt to use an external reference clock for this purpose. Connect the clock source to the REF IN input on the back I/O panel of the oscilloscope using a BNC cable.
  • Page 49 Acquisition Replay Acquisition History This is a good way to begin using History Mode. Watching a "movie" of the history allows you to see waveform changes that are invisible during real-time acquisition. Select View History to enable the display, then use the Navigation buttons to "scroll" the history of acquisitions.

  • Page 50: Trigger

    WaveSurfer 3000/3000z 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 51: Trigger Types

    Qualified arms on the A event, then triggers on the B event. In Normal trigger mode, it automatically resets after the B event, and re-arms upon the next matching A event. Note: This functionality is identical to Teledyne LeCroy's previous Qualify and State triggers, but presented through a different user interface.
  • Page 52 WaveSurfer 3000/3000z Oscilloscopes Operator's Manual Trigger Set Up To open the Trigger dialog, press the front panel Trigger Setup button or touch the Trigger descriptor box. Different controls will appear depending on the Trigger Type selected (e.g., Slope for Edge triggers).
  • Page 53 Acquisition For digital pattern triggers, the level is determined by the Logic Family that is set on the digital group. This can also be specified by a custom (User-Defined) crossing Threshold. Usually, there will be a separate Levels tab for these settings. Conditions (Smart Triggers) Smart triggers all allow you to apply Boolean logic to refine the triggering condition beyond simply Level and Slope/Polarity.
  • Page 54 WaveSurfer 3000/3000z Oscilloscopes Operator's Manual Note: Analog patterns always assume a logical "And" when combined with any digital pattern. Both conditions must be true for the trigger to fire. 4. To set a Time Condition in which the pattern must occur once the trigger is armed, choose the operator: Less Than to trigger only if the pattern occurs before the time set.

  • Page 56: Trigger Holdoff

    WaveSurfer 3000/3000z 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 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 57 Acquisition Note: Because there is only one trigger per acquisition, the trigger event will always belongs to the new acquisition. The processing time shown here is for purposes of illustration only. Regardless of where in the acquisition record the trigger event was found (first edge or last), the display will show time pre- and post-trigger based on your Time/Div and Delay settings.
  • Page 58 WaveSurfer 3000/3000z Oscilloscopes Operator's Manual Holdoff Set Up To add Holdoff to an Edge trigger, touch the Trigger descriptor box or press the front panel Trigger Setup button, then open the Holdoff tab. Choose to Holdoff by Time (the clock) or Events.

  • Page 61: Display

    Display 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. Auto Grid is enabled by default. This feature divides the screen as needed when new traces open. WaveSurfer oscilloscopes may be divided into a maximum of three grids—one each for channels/memories, math functions, and zooms—that each represent the full number of vertical levels.

  • Page 62: Grid Intensity

    WaveSurfer 3000/3000z Oscilloscopes Operator's Manual Grid Intensity 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. Note: Some waveforms may be hidden from view with the grid on top.

  • Page 63: 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".
  • Page 64 WaveSurfer 3000/3000z Oscilloscopes Operator's Manual the intensity will saturate (become brighter) at the percentage value specified. Lowering this percentage causes the pixels to be saturated at a lower population and makes visible those events rarely seen at higher saturation levels.

  • Page 65: 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 for all samples in an acquisition, enabling you to rapidly and thoroughly calculate thousands or millions of parameter values and apply a variety of mathematical functions to the input waveform trace.

  • Page 68: Measure

    WaveSurfer 3000/3000z Oscilloscopes 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. Measurements can also be graphed as a trend for statistical analysis.
  • Page 69 Math and Measure Parameter Set Up The Measure Dialog gives quick access to measurement features. Besides configuring parameters, use the Measure dialog to show Statistics and Histicons, or to Gate measurements. 1. To open the Measure dialog, choose Measure > Measure Setup from the menu bar. 2.
  • Page 70 WaveSurfer 3000/3000z Oscilloscopes Operator's Manual Gating Measurements By using gates, you can narrow the span of the waveform on which to perform tests and measurements, allowing you to focus on the area of greatest interest. For example, if you "gate" five rising edges of the waveform, rise time calculations are performed only on the five pulses bounded by the gate posts.
  • Page 71 Math and Measure Although a Track plots measurement values, it is created as a Math function and controlled on the Function dialogs. 1. On the Fn dialog, choose the Track Operator. 2. On the Track subdialog, use Find Scale to automatically find suitable values, or uncheck Auto Find Scale and enter a custom Center and Height/div.

  • Page 74: Calculating Measurements

    WaveSurfer 3000/3000z Oscilloscopes Operator's Manual Calculating Measurements The instrument uses the following methods to calculate 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.
  • Page 75 Math and Measure 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, or with respect to the specified level for @level parameters.

For example, for a sweeps (weight) value of 4: Sweep New Average = 1 (no old average yet) (new data +0 * old average)/(0 + 1) = new data only (new data + 1*old average)/(1 + 1) = 1/2 new data +1/2 old average...
  • Page 80 WaveSurfer 3000/3000z Oscilloscopes Operator's Manual The instrument's constant phase finite impulse response (FIR) filters provide fast computation, excellent step response in 0.5 bit steps, and minimum bandwidth reduction for resolution improvements of between 0.5 and 3 bits. Each step corresponds to a bandwidth reduction factor of two, allowing easy control of the bandwidth resolution trade-off.
  • Page 81 Math and Measure FFT Function For a large class of signals, you can gain greater insight by looking at spectral representation rather than time description. Signals encountered in the frequency response of amplifiers, oscillator phase noise and those in mechanical vibration analysis, for example, are easier to observe in the frequency domain. If sampling is done at a rate fast enough to faithfully approximate the original waveform (usually five times the highest frequency component in the signal), the resulting discrete data series will uniquely describe the analog signal.
  • Page 82 WaveSurfer 3000/3000z Oscilloscopes Operator's Manual Choosing a Window The choice of a spectral window is dictated by the signal's characteristics. Weighting functions control the filter response shape, and affect noise bandwidth as well as side lobe levels. Ideally, the main lobe should be as narrow and flat as possible to effectively discriminate all spectral components, while all side lobes should be infinitely attenuated.

    Analysis Tools Pass/Fail Testing Pass/Fail testing is a type of mask testing that is particularly useful for comparing newly acquired signals to a previously acquired "golden standard" waveform. Note: Pass/Fail testing does not work with Sequence Mode acquisitions. A mask defines an area of the grid against which a source Channel, Zoom, or Math trace is compared. Test conditions are associated with the mask, defining how the waveform is to be compared to the masked area (e.g., some/all values fall within, some/all values fall outside), and a pass or fail result is returned indicating the condition was found to be true or false.
