    Clears the list of processing steps assigned to the given channel.

    datatype_icon

    session in

    Identifies a particular instrument session.

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input 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.

    Default: No error

    datatype_icon

    channels

    The channel from which to acquire data.

    Channel String Syntax

    You can input channels with the following options:
    • A single channel, such as 0
    • A list of channels, such as 0,1 or 3,2,1,0.
    • A range of channels, such as 0-7 or 0:7.

    Note  

    The order of channels in a list is important. The data for each channel is returned in the order the channels occur in the list.

    datatype_icon

    session out

    Passes the instrument handle to the next node in the program. This parameter has the same value as session in.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Processing Steps

    The processing steps are added with Add Waveform Processing, where the steps are completed in the same order in which they are registered. The processing measurements are streamed, so the result of the first processing step is used as the input for the next step. The processing is also done before any other measurements.
