Dialog Box Options

Option Description
Signal Specifications Contains the following options:
  • Define Signal—

    Displays the Define Signal dialog box, which you use to generate an arbitrary signal.

  • Start over when end of signal is reached—

    Continuously simulates the signal you defined.

    • X values repeat (0, 1, 2, 0, 1, 2)—

      Repeats the x values when you select Start over when end of signal is reached.

    • X values continue (0, 1, 2, 3, 4, 5)—

      Sequentially increments the x values when you select Start over when end of signal is reached.
Signal Generation Contains the following options:
  • One point per iteration—

    Simulates one point per iteration.

  • Entire signal each iteration—

    Simulates the entire signal each iteration.

  • One defined Y point per iteration (no interpolation)—

    Simulates one defined Y point per iteration without using interpolation.
Signal Name

Specifies the name of the signal to display on the block diagram.
Result Preview

Displays a preview of the signal to be simulated.

  • Number of points—

    Displays the number of data points in the signal you defined in the Define Signal dialog box.

Inputs/Outputs

  • cbool.png Reset —

    Controls the initialization of the internal state of the VI. The default is FALSE.

  • cbool.png Next Value —

    Specifies the next value of the signal. The default is TRUE. If FALSE, the Express VI outputs the same value for each iteration.

  • cerrcodeclst.png error in (no error) —

    Describes error conditions that occur before this node runs.

  • iexpdynwdt.png Signal —

    Returns the output signal formatted as dynamic data.

  • ierrcodeclst.png error out —

    Contains error information. This output provides standard error out functionality.

  • ibool.png Data Valid —

    Indicates whether the data is valid.
