Owning Palette: Jitter VIs

Requires: Jitter Analysis Toolkit

Computes the differences between elements in an array of measurements at the interval you specify.

This VI is similar to the Cycle-to-Cycle Measurement VI, except this VI can compute value differences in elements at a specific interval.

sequence contains measurements whose differences you want to compute.
timestamps describes the waveform in which the measurements occur.
t0 specifies the time at which the first sample occurs in the original waveform.
dt specifies the time interval in seconds between the individual samples in the original waveform.
indexes contains the index numbers of samples in the waveform from which the measurements were taken.
N specifies the interval at which to compute differences in the input sequence. For example, if N is 2, this VI subtracts the value of the first element from the value of the third element, the value for the second element from the value for the fourth element, and so on.
N cycle sequence returns the differences between the elements in the input sequence at the interval you specify.
N cycle timestamps returns timing information about the waveform that allows you to identify the times at which measurements in the corresponding sequence occur.
t0 returns the time at which the first sample occurred in the original waveform.
dt returns the time interval in seconds between the individual samples in the original waveform.
indexes returns the index numbers of the measurements in the waveform.
