  • Patent number: 12222831
    Abstract: A method for testing a data-transferring arrangement includes (c) acquiring a channel output-side data set, (d)(e) evaluating the channel output-side data set to determine an error distribution and a bit error ratio in the channel output-side data set, (f) determining at least one test subsequence, (g) forming a further test data set with at least the determined test subsequence, (h) applying the further test data set to the data-transferring arrangement, (i) acquiring a present channel output-side data set based on the further test data set, (j)(k) evaluating the present channel output-side data set to determine a present error distribution and to determine a present bit error ratio in the present channel output-side data set, comparing the present bit error ratio with a predetermined threshold value and, if the comparison reveals that the bit error ratio is larger than the predetermined threshold value, repeatedly carrying out steps (f) to (k).

  • Publication number: 20060229835
    Abstract: Random and deterministic components of jitter are separated. A measured value for deterministic jitter and a plurality of values for random jitter are used to calculate a plurality of first ratios (?ml) of random jitter to deterministic jitter. For each of the plurality of values for random jitter, the value for random jitter is convolved with the measured value for deterministic jitter and a double delta approximation is performed on the result to calculate a plurality of second ratios (?dd) of random jitter to deterministic jitter. A double delta approximation is performed on a measured jitter distribution to obtain a ratio (?ddmeas) of random jitter to deterministic jitter. The ratio (?ddmeas) is adjusted using a relationship of the plurality of first ratios (?ml) to the plurality of second ratios (?dd) in order to produce a corrected ratio (?mlcorr).

  • Publication number: 20060229836
    Abstract: A random component of jitter and a deterministic component of jitter are separated. A measured jitter distribution is obtained. A form is selected for a selected component of jitter. The selected component of jitter is either the random component of jitter or the deterministic component of jitter. A remaining component of jitter is either the random component of jitter or the deterministic component of jitter, whichever is not the selected component of jitter. The selected form for the selected component of jitter is convolved with a generalized function for the remaining component of jitter to produce a resulting equation. The resulting equation is fitted to the measured jitter distribution.
