Method, computer program product, test signal and test device for testing a data-transferring arrangement including a transmitter, channel and receiver

A non-transitory computer-readable medium on which a computer program is stored which, when executed by a processor, causes the processor to:

• (a) generate an initial test data set with a predetermined minimum number of repetitions;
• (b) apply the initial test data set to the data-transferring arrangement;
• (c) acquire a channel output-side data set based on the initial test data set;
• (d) evaluate the channel output-side data set to determine an error distribution in the channel output-side data set, wherein the error distribution indicates at what points of the channel output-side signal errors have occurred based on a comparison of the channel output-side data set with the initial test data set;
• (e) evaluate the channel output-side data set to determine a bit error ratio in the channel output-side data set;
• (f) determine at least one test subsequence by evaluating the error distribution;
• (g) form a further test data set with at least the determined test subsequence;
• (h) apply the further test data set to the data-transferring arrangement;
• (i) acquire a present channel output-side data set based on the further test data set;
• (j) evaluate the present channel output-side data set to determine a present error distribution in the present channel output-side data set;
• (k) evaluate the present channel output-side data set to determine a present bit error ratio in the present channel output-side data set;
• (l) compare 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);
• and
• (m) evaluate the present channel output-side data set for error analysis if the comparison reveals that the present bit error ratio is less than the predetermined threshold value.

• evaluate the channel output-side data set to determine a bit error ratio in the channel output-side data set,
• determine a further test data set with at least the determined test subsequence,
• apply the further test data set to the data-transferring arrangement, to determine a present channel output-side data set based on the further test data set,
• evaluate the present channel output-side data set to determine a present error distribution in the channel output-side data set,
• evaluate the present channel output-side data set to determine a present bit error ratio in the present channel output-side data set, to compare 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, to carry out, in particular repeatedly carry out, at least one process of determining at least one further test subsequence by evaluating the further error distribution, and
• evaluate the channel output-side data set for error analysis if the comparison reveals that the present bit error ratio is less than the predetermined threshold value.
