IviDigitizer Configure Edge Trigger Source (G Dataflow)

Version:
    Last Modified: October 24, 2017

    Sets the edge triggering properties. An edge trigger occurs when the trigger signal that the end-user specifies in the Trigger Source input passes through the voltage threshold that the end-user specifies in the Trigger Level input and has the slope that the end-user specifies in the Trigger Slope input. This node affects instrument behavior only if the IviDigitizer Trigger Type property is set to edge trigger. Set the IviDigitizer Trigger Type property and the IviDigitizer Trigger Coupling property before calling this node. If the trigger source is one of the analog input channels, an application program should configure the vertical range, vertical coupling, and the maximum input frequency before calling this node.

    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.

    error in

    Error conditions that occur before this node runs.

    Default: None

    Trigger Level (1.0)

    Specifies the trigger level. This value sets the IviDigitizer Trigger Level property. Unit: volt Default Value: 1.0

    datatype_icon

    Trigger Source ("")

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

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
