摘要： A method and apparatus of processing waveforms acquired in a waveform digitizing instrument utilizing multiple, interleaved digitizing elements is provided to improve the accuracy of the data acquired is provided. The present method utilizes measured analog-to-digital converter frequency response characteristics to generate sets of coefficients. When data is acquired by a waveform digitizing system, the present method utilizes these coefficients to correct the waveform, thus undoing the adverse effects of the non-ideal frequency response characteristics, resulting in a waveform acquired with higher fidelity. The waveform resulting from this method is a waveform that more closely represents the signal sampled by the digitizing system.

摘要： A system that improves acquisition fidelity in high-bandwidth interleaved acquisition systems through a process called sample-synthesis. Synthesizers are used to make data from one digitizing element appear as though it were sampled by another digitizing element. This method overcomes the Nyquist limitations imposed on a single digitizer. The topology for this system is described, and an explanation of the operation is provided. Then, details are provided for the consideration of Infinite Impulse Response (IIR) and Finite Impulse Response (FIR) filter implementations of sample synthesizers.

摘要： Apparatus and associated systems, methods and computer program products relate to isolating horizontal jitter component(s) from vertical jitter component(s). In preferred embodiments, at least one horizontal component of jitter is distinguished from at least one component of vertical jitter by fitting a curve to a digitally acquired waveform, determining the curve slope and statistical variance about the fitted curve over at least one time period, identifying a functional relationship between the variance and slope, and determining therefrom at least one horizontal component of jitter and at least one vertical component of jitter. Random and deterministic jitter components may be aggregated, in certain embodiments, so as to identify a vertical jitter component that reflects both deterministic and random jitter. In preferred implementations, the isolated vertical jitter component is subtracted from a total jitter measurement so as to better approximate actual signal jitter.

摘要： A system for estimating bit error rates (BER) may include using a normalization factor that scales a BER to substantially normalize a Q-scale for a distribution under analysis. A normalization factor may be selected, for example, to provide a best linear fit for both right and left sides of a cumulative distribution function (CDF). In some examples, the normalized Q-scale algorithm may identify means and probabilistic amplitude(s) of Gaussian jitter contributors in the dominant extreme behavior on both sides of the distribution. For such contributors, means may be obtained from intercepts of both sides of the CDF(Qnorm(BER) with the Q(BER)=O axis, standard deviations (sigmas) may be obtained from reciprocals of slopes of best linear fits, and amplitudes may be obtained directly from the normalization factors. In an illustrative example, a normalized Q-scale algorithm may be used to accurately predict bit error rates for sampled repeating or non-repeating data patterns.

摘要： A method and apparatus for acquiring a signal 110 employing a coherent timebase are provided. The method comprises the steps of defining a pattern length count 360 of a repetitive pattern in a signal 110 to be acquired, defining a number of samples per unit interval, and providing data strobes 225 synchronous to a coherent timebase. An arbitrary one of the data strobes is designated as a timing for a potential trigger 120. A number of subsequent data strobes is counted 360 in accordance with the pattern length count times the samples per unit interval and a portion of the signal corresponding to the pattern length count times the samples per unit interval is acquired beginning at a point in the signal defined by the designated arbitrary data strobe. Thereafter one or more additional portions of the signal 110 are acquired 435 corresponding to the pattern length count times the samples per unit interval at a point 150 in the signal 110 defined by when the number of subsequent data strobes reaches the pattern length count times the samples per unit interval.
