摘要： An Arbitrary Waveform Generator (AWG) synthesizes and generates an SSC modulated signal by generating a modulating waveform with a frequency of an SSC modulation frequency, calculating the number of samples per data bit (SPUI) as a ratio of an upsampling frequency to a data rate of a data stream, calculating an amplification factor as the ratio of SSC deviation frequency to data rate of the data stream, generating the array of SSC Edges containing the edge variation with respect to single sample per bit, multiplying the amplification factor to the modulating waveform, generating an array of SSC Edges Upsampled, containing edge variations with respect to an Upsample factor per bit, and multiplying SSC Edges with SPUI; calculating the resultant bit duration SSC Bit Duration as the sum of SSC Edges Upsampled and SPU, and calculating the successive summation of SSC Bit Duration, to get SSC Bit Position.

摘要： A method for identifying spectral impulses applies a window filter to an acquired waveform to produce a filtered waveform, and performs an FFT function on the filtered waveform to produce a spectrum of bins. An estimating window is located on the spectrum and centered on a target bin. Bins adjacent to the target bin are excluded and the remaining bins are used to form a noise estimate. The estimate is compared to the target bin and if the result exceeds a threshold value, a spectral impulse is identified.

摘要： A method for analyzing jitter using a test and measurement instrument includes obtaining a collection of time interval error (TIE) values corresponding to composite jitter of a waveform, optionally decomposing the composite jitter into jitter components that are correlated to the data pattern and components that are uncorrelated to the data pattern, and using a spectral approach to decompose the jitter components into jitter components that are recognizable as deterministic and jitter components that are unrecognizable as deterministic. Thereafter, the jitter components analyzed in the frequency domain are converted back to the time domain, and subtracted from the composite jitter, thereby isolating uncorrelated residual jitter. The uncorrelated residual jitter is decomposed into bounded uncorrelated jitter and random jitter, for example, by integrating a probability density (PDF) function of the residual jitter and analyzing the resulting cumulative distribution function (CDF) curve in Q-space.
