    timestamp array

    Array of 64-bit timestamps returned from the RT Get Timestamp node that you want to analyze.

    datatype_icon

    calibration array

    An array used to account for the time required for the RT Get Timestamp node to execute. The RT Timestamp Analysis node subtracts the mean value of all elements in calibration array from each element in timestamp array to remove the timestamp errors introduced when the RT Get Timestamp node adds the element to the timestamp array in memory on the RT target.

    datatype_icon

    warmup iterations

    Number of timestamps to ignore from the beginning of timestamp array. Use Warmup iterations to remove initial timestamps from the beginning of timestamp array that might have been affected during the initial execution of the application on an RT target.

    datatype_icon

    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error

    datatype_icon

    mean time (μS)

    Average execution time for the values in the execution times array.

    datatype_icon

    standard deviation (μS)

    Standard deviation for the values in the execution times array.

    datatype_icon

    execution times (μS)

    Execution time, in microseconds, between each element of timestamp array.

    datatype_icon

    execution histogram

    Histogram values for the elements of execution times.

    datatype_icon

    max jitter (μS)

    Maximum deviation between elements of execution time and the value of mean time. The value can represent a positive or negative deviation.

    datatype_icon

    error out

    Error information. The node produces this output according to standard error behavior.

    Where This Node Can Run:

    Desktop OS: none

    FPGA: Not supported
