Patent ID: 8332172

Claim:
A method of modifying measured or synthesized pattern data and jitter and noise components in a signal comprising the steps of: acquiring digital data samples of a signal using the digitizing instrument; generating correlated pattern data of the sampled signal using the digitizing instrument; acquiring digital data samples of the signal for respectively generating observed jitter and observed noise components using the digitizing instrument; characterizing random jitter and noise components and periodic jitter and noise components from the observed jitter and observed noise components of the sampled signal using the digitizing instrument; selectively modifying the correlated pattern data, uncorrelated random jitter and noise components, and uncorrelated periodic jitter and noise components of the sampled signal for each element of a plurality of elements in a simulated signal path using the digitizing instrument; combining the selectively modified correlated pattern data, random jitter and noise components, and periodic jitter and noise components of the sampled signal using the digitizing instrument; displaying the result of the combination of the selectively modified correlated pattern data, uncorrelated random jitter and noise components, and uncorrelated periodic jitter and noise components of the sampled signal illustrating changes in at least one of an eye diagram, bit error rate eye and numeric table displays as a function of selectively modifying the correlated pattern data, uncorrelated random jitter and noise components and uncorrelated periodic jitter and noise components of the sampled signal using the digitizing instrument.
