Owning Palette: Level VIs
Requires: Jitter Analysis Toolkit
Measures the areas and mean voltages of unit intervals in a waveform. Wire data to the waveform input to determine the polymorphic instance to use or manually select the instance.
Use the pulldown menu to select an instance of this VI.
This instance operates on the waveform data type when the Y data values are doubleprecision, floatingpoint numeric values. Use the I8 instance of this VI with integer data to reduce the size of the data and the memory usage.
waveform is the waveform to measure.
 
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.
 
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.  
rising/falling specifies the direction of the transition at which to begin the measurement. This VI begins measuring at the first transition of that direction in the waveform.


area sequence returns an array of the areas that cycles in the waveform occupy.  
Vavg sequence returns an array of the mean values of the voltages in each cycle. In other words, these values are the sums of the voltage values divided by the measurement time in samples. Each element of Vavg sequence corresponds to an element of area sequence.  
sequence 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. 
This instance operates on the waveform data type when the Y data values are 8bit signed integers.
