System and method for adjusting a sampling time in a logic analyzer

A system for detecting a stable region in a data signal, comprising:

• sampling means for performing a simultaneous sampling of a reference signal and a delayed version of the reference signal to ascertain a number of transitions at a selectable position of the reference signal with respect to an associated clock input;
• and
• detection means for detecting a boundary of the stable region of the reference signal by sampling a number of the selectable positions of the reference signal according to a search pattern.
