With this function the bar can align with the waveform edge automatically to avoid measurement error.

During operating oscilloscope, some error may be caused by the cursor not completely aligned with the waveform edge, and this same problem may happen during operating Logic Analyzer when using the bar. See Fig.1 and Fig.2.

Fig.1: Align the A bar with the rising edge by hand.

Fig.2: Enlarge the waveform with A bar be the center, then it is obvious to see some distance exists between
A bar and rising edge.

Zeroplus Logic Analyzer provides the bar auto-close function. The software will auto-close the bar with the object edge.

Fig.3: Set the Bar Auto-close function.

Fig.4: With the auto-close function, the bar will auto-close the edge while being moved to it.
