If you chose Sequence Mode, touch the Smart Memory tab, then touch inside the Num Segments field and enter a value using the pop-up numeric keypad.
Page 50: Sequence Mode Setup
UNNER ERIES Each individual segment can be zoomed or used as input to math functions. The instrument uses the sequence timebase setting to determine the capture duration of each segment: 10 x time/div. Along with this setting, the oscilloscope uses the desired number of segments, maximum segment length, and total available memory to determine the actual number of samples or segments, and time or points.
Page 51: Sequence Display Modes
’ PERATOR ANUAL Sequence Display Modes The instrument gives you a choice of five ways to display your segments: DJACENT ATERFALL CASCADED OSAIC TILED VERLAY ERSPECTIVE The number of segments you choose to display (80 maximum) can be less than the total number of segments in the waveform.

Page 58 UNNER ERIES State The State trigger is a level-qualified trigger which requires that the qualifying signal remain above or below a specified voltage level for a trigger to occur. For Sate trigger, you specify the time or number of events after the signal has gone above or below the voltage level when you want the trigger to occur.
Page 59: Determining Trigger Level, Slope, Source, And Coupling
’ PERATOR ANUAL Determining Trigger Level, Slope, Source, and Coupling 1. Level defines the source voltage at which the trigger circuit will generate an event: a change in the input signal that satisfies the trigger conditions. The selected trigger level is associated with the chosen trigger source.
Page 60: Level
UNNER ERIES Level Level defines the source voltage at which the trigger circuit will generate an event (a change in the input signal that satisfies the trigger conditions). The selected trigger level is associated with the chosen trigger source. Note that the trigger level is specified in volts and normally remains unchanged when the vertical gain or offset is modified.
Page 61: Hold Off By Events
’ PERATOR ANUAL Hold Off by Events Select a positive or negative slope and a number of events. An event is the number of times the trigger condition is met after the last trigger. A trigger is generated when the condition is met after this number, counted from the last trigger.
Page 62: Edge Trigger Setup
UNNER ERIES Alternatively, in the Trigger dialog, you can touch inside the Level field and type in a value, using the pop-up numeric keypad. To quickly set a level of zero volts, touch the Zero Level button directly below the Coupling field.

UNNER ERIES 3. Touch inside the Grid Intensity field and enter a value from 0 to 100 using the pop-up keypad. 4. Touch the Grid on Top checkbox if you want to superimpose the grid over the waveform. Depending on the grid intensity, some of your waveform may be hidden from view when the grid is placed on top.
Page 73: Saturation Level
’ PERATOR ANUAL Saturation Level The Persistence display is generated by repeated sampling of the amplitudes of events over time, and the accumulation of the sampled data into "3-dimensional" display maps. These maps create an analog-style display. User-definable persistence duration can be used to view how the maps evolve proportionally over time. Statistical integrity is preserved because the duration (decay) is proportional to the persistence population for each amplitude or time combination in the data.
Page 74 UNNER ERIES Here is an example of a 3-dimensional view of a square wave using the solid view of color-graded persistence. Saturation is set at 50%, with red areas indicating highest intensity. The X-axis has been rotated 60%; the Y-axis has been rotated 15%. Here is a monochrome (analog) view of the same waveform.
Page 75: Show Last Trace
’ PERATOR ANUAL Show Last Trace For most applications, you may not want to show the last trace because it will be superimposed on top of your persistence display.

Page 96: Histogram Theory Of Operation
UNNER ERIES Histogram Theory of Operation An understanding of statistical variations in parameter values is needed for many waveform parameter measurements. Knowledge of the average, minimum, maximum, and standard deviation of the parameter may often be enough, but in many cases you may need a more detailed understanding of the distribution of a parameter's values.

Page 99: Binning And Measurement Accuracy
’ PERATOR ANUAL However, signal noise and the use of a high number of bins relative to the number of parameter values acquired, can give a jagged and spiky histogram, making meaningful peaks hard to distinguish. The oscilloscope analyzes histogram data to identify peaks from background noise and histogram definition artifacts such as small gaps, which are due to very narrow bins.

Page 132 UNNER ERIES 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.

In low-pass filtering: The spectrum of a square signal before (left top) and after (left bottom) enhanced resolution processing.

Page 136: Power (Density) Spectrum
This variation in spectrum magnitude is the picket fence effect. The corresponding attenuation loss is referred to as scallop loss. LeCroy oscilloscopes automatically correct for the scallop effect, ensuring that the magnitude of the spectra lines correspond to their true values in the time domain.
Page 137: Improving Dynamic Range
The SNR increase is conditioned by the cut-off frequency of the ERES low-pass filter and the noise shape (frequency distribution). LeCroy digital oscilloscopes employ FIR digital filters so that a constant phase shift is maintained. The phase information is therefore not distorted by the filtering action.
Page 138: Fft Algorithms
UNNER ERIES An effective way to reduce these effects is to maximize the acquisition record length. Record length directly conditions the effective sampling rate of the oscilloscope and therefore determines the frequency resolution and span at which spectral analysis can be carried out. FFT Algorithms A summary of the algorithms used in the oscilloscope's FFT computation is given here in a few steps: The data are multiplied by the selected window function.

’ PERATOR ANUAL where M = 0.316 V (that is, 0 dBm is defined as a sine wave of 0.316 V peak or 0.224 V rms, giving 1.0 mW into 50 ohms). The dBm Power Spectrum is the same as dBm Magnitude, as suggested in the above formula. dBm Power Density: where ENBW is the equivalent noise bandwidth of the filter corresponding to the selected window, and Delta f is the current frequency resolution (bin width).
Page 140 UNNER ERIES For a real source waveform (imaginary part equals 0), there are only N/2 independent harmonic components. An FFT corresponds to analyzing the input signal with a bank of N/2 filters, all having the same shape and width, and centered at N/2 discrete frequencies. Each filter collects the signal energy that falls into the immediate neighborhood of its center frequency.
