Owning Palette: Signal Analysis Express VIs
Requires: Full Development System
Returns the selected parameter of the first signal in a waveform.
Dialog Box Options 
Block Diagram Inputs 
Block Diagram Outputs 
Parameter  Description 

Statistical Calculations  Contains the following options:

Extreme Values  Contains the following options:

Sampling Characteristics  Contains the following options:

Input Signal  Displays the input signal. If you wire data to the Express VI and run it, Input Signal displays real data. If you close and reopen the Express VI, Input Signal displays sample data until you run the Express VI again. 
Results  Displays the measurements you configured this Express VI to perform and the calculated values of those measurements. You can click any measurement listed in the Measurement column, and the corresponding value or plot appears in the Result Preview graph. 
Parameter  Description 

Signals  Contains the input signal or signals. 
error in  Describes error conditions that occur before this node runs. 
Parameter  Description 

Summation  Returns the value of the sum of all the values in Signals. 
Kurtosis  Returns the kurtosis of the values in Signals. Kurtosis is a measure of peakedness and corresponds to the fourthorder moment about the mean. 
Skewness  Returns the skewness of the values in Signals. Skewness is a measure of symmetry and corresponds to the thirdorder moment about the mean. 
Total Samples  Returns the total number of samples in Signals. 
Index of Max  Returns the index value of the highest point of the values in Signals. 
Mode  Returns the value that occurs most often in the set values in Signals. 
Variance  Returns the calculated variance of the values in Signals. 
RMS  Returns the calculated RMS of the values in Signals. 
Time Delta  Returns the time between samples in Signals. 
Last Value  Returns the last value in Signals. 
First Value  Returns the first value in Signals. 
First Time  Returns the first time value in Signals. 
Range  Returns the value of the range from the lowest point to the highest point in a set of values in Signals. 
Time of Minimum  Returns the time of the lowest point of the values in Signals. 
Minimum  Returns the lowest point in a set of values in Signals. 
Time of Maximum  Returns the time of the highest point of the values in Signals. 
Maximum  Returns the highest point in a set of values in Signals. 
error out  Contains error information. This output provides standard error out functionality. 
Last Time  Returns the last time value in Signals. 
Arithmetic Mean  Returns the mean, or average, of the values in Signals. 
Standard Dev  Returns the standard deviation of the values in Signals. 
Median  Returns the median value in Signals. The Express VI sorts the values in Signals and selecting the middle element of the sorted values. 
Index of Min  Returns the index value of the lowest point of the values in Signals. 
This Express VI operates similarly to the following VIs and functions:
Get Waveform Components (Analog Waveform)
Get Final Time Value
Number of Waveform Samples
Waveform Duration
Waveform Min Max
Waveform Peak Detection
And Array Elements
Refer to the Express VI  Statistics VI in the labview\examples\Express VIs directory for an example of using the Statistics Express VI.
