Owning Palette: Jitter VIs

Requires: Jitter Analysis Toolkit

Computes the differences between consecutive elements of an array of measurements.

Details  

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.
cycle-to-cycle sequence returns the differences between the elements of the input sequence.
cycle-to-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.

Cycle-to-Cycle Measurement Details

You can use this VI to measure cycle-to-cycle differences in the output sequences that many Jitter Analysis Toolkit VIs return. For example, you can wire the + width sequence output from the Positive Width VI to this VI to see how the positive widths of cycles change between successive cycles, as shown in the following block diagram.
