Sends a command to trigger the spectrum analyzer.
Call this node if you pass IVISPECAN_VAL_TRIGGER_SOURCE_SOFTWARE for the IviSpecAn>>Trigger>>Trigger Source property or the Trigger Source parameter of the IviSpecAn Configure Trigger Source [TRG] node.
This node does not check the instrument status. Typically, you call this node only in a sequence of calls to other low-level driver nodes. The sequence performs one operation. You use the low-level nodes to optimize one or more aspects of interaction with the instrument. If you want to check the instrument status, call the IviSpecAn Error-Query Node at the conclusion of the sequence.
The instrument handle that you obtain from the IviSpecAn Initialize Node or IviSpecAn Initialize With Options Node. The handle identifies a particular instrument session.
Default: None

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.
