Abstract
A capture scheme detects repetitive occurrences of finite-length bit patterns within an applied data signal to provide trigger events for equivalent time sampling of the data signal. The capture scheme enables acquisition of samples within designated bit patterns of the data signal, independent of whether the data signal is random in nature, since the designated finite-length bit patterns occur repetitively within the data signal. In an apparatus implementation of the capture scheme, a bit pattern detector detects a designated bit pattern within the applied data signal and generates trigger events responsive to the occurrences of the bit pattern. An equivalent time sampler receives the data signal and trigger events to acquire samples of the data signal within the designated bit pattern. The capture scheme is alternatively implemented as a method including the steps of detecting a designated bit pattern, generating trigger events responsive to the occurrences of the bit pattern and acquiring equivalent time samples of the data signal according to the trigger events.
