Amplitude Measurements (AC DC and RMS » Basic Continuous) (G Dataflow)

    Last Modified: January 9, 2017

    Calculates continuous AC, DC, and RMS values of a signal.



    A Boolean that specifies the initialization of the internal state of the node.

    True Initializes the internal state to zero.
    False Initializes the internal state to the final state from the previous call of this node.

    This node automatically initializes the internal state to zero on the first call and runs continuously until this input is True.

    Default: False



    The input signal.

    This input can be a waveform or an array of waveforms.


    averaging type

    Type of averaging to apply to the signal.

    Name Description
    Linear Applies linear averaging to the signal.
    Exponential Applies exponential averaging to the signal.

    Default: Linear


    window type

    Type of window to apply to the signal when you use linear averaging.

    Windowing can help increase measurement accuracy for signals that are dominated by periodic components.

    Name Description
    Rectangular (none) Does not apply a window.
    Hanning Applies a Hanning window.
    Low side lobe Applies a low side lobe window.

    Default: Rectangular (none)


    error in

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

    Default: No error


    AC value

    AC value of the signal.


    DC value

    DC value of the signal.


    RMS value

    Root mean square value of the signal.


    error out

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

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
