IviDigitizer Configure Data Interleaved Channel List [DIC] (G Dataflow)

Version:
    Last Modified: October 24, 2017

    Combines a specified channel with one or more other channels to interleave the returned data.

    The string provided here specifies which channels should operate in combined mode with the current channel. The Channel List input is a comma-separated list of one or more channel names. Users may specify either physical or virtual repeated capability identifiers in this list. An empty string or VI_NULL (0) can be used to indicate that no channels should be combined (or that none are currently combined, in the case of a query).

    spd-note-note
    Note  

    If a channel name specified in the list is not recognized, the driver generates the Unknown Channel Name error. If a channel name specified in the list is not enabled, this property generates the error Channel Not Enabled.

    spd-note-note
    Note  

    Setting this property on a channel designates that channel as the one on which subsequent fetch and read operations should be made. Fetch and read operations will return the data from multiple channels, so care should be taken to ensure that sufficient memory is allocated.

    Channel List ("")

    Specifies one or more channel names to combine with the channel specified in the Channel Name input. Use commas to separate channel names in this list. This value sets the IviDigitizer Data Interleaved Channel List property. Users who want to achieve interchangeability should use a virtual channel name. The virtual channel name should be sufficiently specific to the test system such that it is unlikely to conflict with a physical channel name. Default Value: "" Note: You can specify the trace name as a string variable or as a literal enclosed in double quotes.

    Channel Name ("")

    Specifies the name of the channel to be combined with those in the Channel List input. Users who want to achieve interchangeability should use a virtual channel name. The virtual channel name should be sufficiently specific to the test system such that it is unlikely to conflict with a physical channel name. Default Value: "" Note: You can specify the trace name as a string variable or as a literal enclosed in double quotes.

    instrument handle out

    The instrument handle that you obtain from the IviDigitizer Initialize Node or IviDigitizer Initialize With Options Node. The handle identifies a particular instrument session.

    Default: None

    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.
