In-depth Description
The Locktime tool enables the user to view the measured value of the signal, on either or both
channels, with respect to its cycle count starting from some trigger/arming point supplied by a pulse
generator, ATE system or circuit under test.
For example, the Locktime tool would be used to measure PLL frequency or period settling time from
the point where the change was initiated.
For the period following the Arm, a histogram of time measurements is created. The period being
measured is then incremented to the 2nd period following the arm and a histogram is created. Then the
3rd period is repeatedly sampled to create a histogram and this process repeats until the Span (edges)
value has been reached. The number of time measurements in each histogram is chosen by Hits per
Edge.
