  • Page 23: Using Maui

    Using MAUI Using MAUI MAUI, the Most Advanced User Interface, is Teledyne LeCroy's unique oscilloscope user interface. MAUI is designed for touch—all important controls for vertical, horizontal, and trigger are only one touch away. Touch Screen The touch screen is the principal viewing and control center. The entire display area is active: use your finger or a stylus to touch, drag, swipe, or draw a selection box.

  • Page 24: Menu Bar

    HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual Menu Bar The top of the window contains a complete menu of functions. Making a selection here changes the dialogs displayed at the bottom of the screen. While many common operations can also be performed from the front panel or launched via the descriptor boxes, the menu bar is the best way to access dialogs for Save/Recall (File) functions, Display functions, Status, LabNotebook, Pass/Fail setup, and Utilities/Preferences setup.

  • Page 25: Grid Intensity

    Using MAUI Grid Indicators These indicators appear around or on the grid to mark important points on the display. They are matched to the color of the trace to which they apply. When multiple traces appear on the same grid, indicators refer to the foreground trace—the one that appears on top of the others.

  • Page 26: Descriptor Boxes

    HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual Descriptor Boxes Trace descriptor boxes appear just beneath the grid whenever a trace is turned on. They function to: Inform—descriptors summarize the current trace settings and its activity status. Navigate—touch the descriptor box once to activate the trace, a second time to open the trace setup dialog.
  • Page 27 Using MAUI Other Trace Descriptor Boxes Similar descriptor boxes appear for math (Fx), zoom (Zx), and memory (Mx) traces. These descriptor boxes show any Horizontal scaling that differs from the signal timebase. Units will be automatically adjusted for the type of trace.

  • Page 40 HDO4000/HDO4000A High Definition 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.

  • Page 41: Zooming

    Using MAUI Zooming Zooms magnify a selected region of a trace by altering the Horizontal Scale relative to the source trace. Zooms may be created in several ways, using either the front panel or the touch screen. You can adjust zooms the same as any other trace using the front panel Vertical and Horizontal knobs or the touch screen zoom factor controls.

  • Page 42: Creating Zooms

    HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual Creating Zooms Any type of trace can be "zoomed" by creating a new zoom trace (Zx) following the procedures here. Note: On instruments with OneTouch, traces can be "zoomed" by pinching/unpinching two fingers over the trace, but this method does not create a separate zoom trace. With channel traces, pinching will alter the acquisition timebase and the scale of all traces.

  • Page 43: Print/Screen Capture

    Using MAUI Adjust Zoom Scale The zoom's Horizontal units will differ from the signal timebase because the zoom is showing a calculated scale, not a measured level. This allows you to adjust the zoom factor using the front panel knobs or the zoom factor controls however you like without affecting the timebase (a characteristic shared with math and memory traces).

  • Page 54: Timebase

    HDO4000/HDO4000A High Definition Oscilloscopes 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.
  • Page 55 Acquisition Real Time Memory Max. Sample 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 instrument allocates memory as needed to maintain the highest sample rate possible for the timebase.

  • Page 56: Sampling Modes

    HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual Sampling Modes The Sampling Mode determines how the instrument samples the input signal and renders it for display. Real Time Sampling Mode Real Time sampling mode is a series of digitized voltage values sampled on the input signal at a uniform rate.
  • Page 57 Acquisition Sequence Sampling Mode In Sequence Mode sampling, the completed waveform consists of a number of fixed-size segments. The instrument uses the Timebase Sequence settings to determine the capture duration of each segment. The desired number of segments, maximum segment length, and total available memory are used to determine the actual number of samples or segments, and time or points.
  • Page 58 HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual Channel descriptor boxes indicate the total number of segments acquired in sequence mode. Zoom descriptor boxes show the first segment displayed and total number of segments displayed ([#] #). As with all other zoom traces, the zoomed segments are highlighted on the source trace.

  • Page 59: History Mode

    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 individual details or changes in the waveforms over time.
  • Page 60 HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual 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.

  • Page 61: Trigger

    Acquisition 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 62: Trigger Types

    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. Smart Triggers Smart triggers allow you to apply Boolean logic conditions to the basic signal characteristics of level, slope, and polarity to determine when to trigger.
  • Page 63 Acquisition Runt triggers when a pulse crosses a first threshold, but fails to cross a second threshold before re- crossing the first. Other defining conditions for this trigger are the edge (triggers on the slope opposite to that selected) and runt width. SlewRate triggers when the rising or falling edge of a pulse crosses an upper and a lower level.
  • Page 64 HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual Slope/Polarity For some triggers, such as Edge, you will be asked to select the waveform Slope (rising vs. falling) on which the triggering event may occur. For others, such as Width, the equivalent selection will be Polarity (positive vs. negative).

    HDO4000/HDO4000A High Definition 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 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.

    HDO4000/HDO4000A High Definition 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 81 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. You can also plot the measurement results as a Trend.
  • Page 82 HDO4000/HDO4000A High Definition 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 83 Math and Measure List of Standard Measurements Measurements included standard with the oscilloscope are listed below alphabetically. Note: There may be additional parameters available depending on the software options installed on the oscilloscope. Measurement Description Measures the difference between upper and lower levels in two-level signals. Differs from pkpk Amplitude in that noise, overshoot, undershoot, and ringing do not affect the measurement.

  • Page 85 Math and Measure Measurement Description Higher of two most probable states (base is lower). Measures higher level in two-level signals. Differs from max in that noise, overshoot, undershoot, and ringing do not affect measurement. On signals not having two major levels (such as triangle or saw-tooth waves), the amplitude parameter returns the same value as minimum.

  • Page 86: Calculating Measurements

    HDO4000/HDO4000A High Definition 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 87 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.

  • Page 92 HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual ERes Function ERes (Enhanced Resolution) filtering increases vertical resolution, allowing you to distinguish closely spaced voltage levels. The instrument's ERes function is similar to smoothing the signal with a simple, moving-average filter. However, it is more efficient concerning bandwidth and pass-band filtering.
  • Page 93 Math and Measure Resolution -3 dB Bandwidth (x Filter Length increased by Nyquist) (Samples) 0.241 0.121 0.058 0.029 0.016 With low-pass filters, the actual SNR increase obtained in any particular situation depends on the power spectral density of the noise on the signal. The improvement in SNR corresponds to the improvement in resolution if the noise in the signal is white (evenly distributed across the frequency spectrum).
  • Page 94 HDO4000/HDO4000A High Definition Oscilloscopes Operator's Manual 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.
  • Page 95 Math and Measure Window Type Applications and Limitations Rectangular 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 fun- damental 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.

  • Page 107: Pass/Fail Testing

    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. Mask Testing 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.
