Waveform Scalar Limit Comparison

Compares the waveform data values to a scalar value. Passed? is FALSE if any point in the waveform fails the specified comparison. For example, Passed? is FALSE if any waveform point is greater than the Limit value when Compare Condition is set to >. This VI also returns an array of waveforms where the first waveform is the original data. The second waveform contains the data with the failed limit comparison values replaced by NaN.

Data is the waveform that includes the data you want to compare to a specified Limit.
Compare Condition indicates whether the highest or lowest data value of waveform must be lower than and/or equal to or higher than and/or equal to the number in Limit. Valid options include the following:

  • > highest or lowest value in the waveform is greater than the Limit (default)
  • => highest or lowest value in the waveform is greater than or equal to the Limit
  • < highest or lowest value in the waveform is less than the Limit
  • <= highest or lowest value in the waveform is less than or equal to the Limit
Limit specifies the number you want to compare the highest or lowest data value in the waveform.
error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
code is the error or warning code. The default is 0. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
Output Waveforms returns two waveforms in an array. The first is a copy of Data. The second is the failure waveform, which is a copy of Data with all elements that passed replaced by NaN. All valid elements are failures.
Passed? indicates whether the highest or lowest data value met the Compare Condition based on the Limit. FALSE indicates the highest or lowest data value did not meet the comparison.
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
code is the error or warning code. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
