ParameterDescription
ConversionContains the following option:
  • Input data type—Specifies the data type that you want to convert to the dynamic data type.
Scalar Data TypeContains the following options:
  • Floating point numbers (double)—Specifies that numeric values are double-precision, floating-point numbers.
  • Boolean (TRUE and FALSE)—Specifies that numeric values are Boolean values.
Start TimeContains the following options:
  • Zero—Sets the t0 of the input signal to zero.
  • Now—Sets the t0 of the input signal to the current system time.
InputsDisplays the input signal. If you wire data to the Express VI and run it, Inputs displays real data. If you close and reopen the Express VI, Inputs displays sample data until you run the VI again.
Results PreviewDisplays a preview of the measurement. The Results Preview plot indicates the value of the selected measurement with a dotted line. If you wire data to the Express VI and run the VI, Results Preview displays real data. If you close and reopen the Express VI, Results Preview displays sample data until you run the VI again. If the cutoff frequency values are invalid, Results Preview does not display valid data.
