    start position B

    The index where you want to start the comparison within digital data B.

    datatype_icon

    start position A

    The index where you want to start the comparison within digital data A.

    datatype_icon

    digital data A

    Digital data you want to use to perform a digital comparison.

    datatype_icon

    digital data B

    Digital data you want to use to perform a digital comparison.

    error in

    Error conditions that occur before this node runs. Unlike most nodes, this node runs normally even if an error occurs before this node runs.

    Default: no error

    datatype_icon

    compare level

    Comparison results that you want this node to return.

    Name Value Description
    Pass/Fail Only 0 Returns only passed? as an output, which improves the performance of the comparison.
    Pass/Fall and Number of Errors 1 Returns passed? and number of failed samples.
    Pass/Fail, Number of Errors and Diff Data 2 Returns passed?, number of failed samples, and diff data.

    Default: Pass/Fail Only

    datatype_icon

    number of samples to compare

    Number of samples to compare in digital data A and digital data B.

    Default: -1—Node compares all samples.

    datatype_icon

    passed?

    A Boolean that indicates whether the values in digital data A and digital data B match.

    True All corresponding values in digital data A and digital data B match.
    False The corresponding values in digital data A and digital data B do not match.
    datatype_icon

    number of failed samples

    Number of corresponding samples in digital data A and digital data B that do not match.

    datatype_icon

    diff data

    Digital data representing the comparison of digital data A and digital data B. Zeros represent corresponding samples that match. Ones represent corresponding samples that differ. You can use this data to determine the exact location of all differing samples.

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.
