Abstract
Error-related information acquired using a bit error ratio detector (BERT) is extrapolated on the basis of prior testing, in which measurements “superior” to those acquired by the BERT are used to provide an initial extrapolation calibration. For example, measures of data dependent jitter acquired by a digital communications analyzer (DCA) may be used to offset the less accurate jitter-related measures by the BERT. As a consequence, the benefits of a DCA and a BERT are combined, while using only the BERT.
