Owning Palette: Jitter VIs
Requires: Jitter Analysis Toolkit
Measures the differences between period times from a waveform and the corresponding ideal periods from the reference clock.
This VI is similar to the Period Jitter VI, except this VI can compute the period jitter between edges at a specific interval, rather than between adjacent edges.
|Np specifies the edge interval at which to compute period jitter. For example, if Np is 2, this VI subtracts the jitter value at the first edge in the waveform from the jitter value at the third edge, the jitter at the second edge from the jitter at the fourth edge, and so on to compute the N period jitter sequence.|
|level crossings contains information about the locations of level crossings in the original waveform. You can use the Level Crossing VI to generate this cluster.
|ref level crossings specifies information about the locations of level crossings in the reference clock waveform. You can use the Clock Recovery VIs to generate this cluster from a measured waveform.
|error in describes error conditions that occur before this node runs. This input provides standard error in functionality.|
|N period jitter sequence is an array of durations of cycles in the waveform, in seconds. In other words, the values represent the differences between the times that transitions at the interval you specify fall on the crossing level.|
|N period jitter timestamps returns timing information about the waveform that allows you to identify the times at which measurements in the corresponding sequence occur.
|error out contains error information. This output provides standard error out functionality.|
