Solution
One of the primary methods for generating and exporting trigger signals with the signal that you are generating with the VST is using Script Mode with the NI-RFSG driver.
In Script Mode, you can configure marker events which you can use to export triggers based on the waveform that you are generating. You can configure the behavior of the marker events to be either Pulse or Toggle. With the Pulse behavior, the marker event will generate a pulse for a specified amount of time. The default value for the pulse width is 200 ns. You can change the amount of time (or width) of the pulse using the Pulse:WidthValue property. The maximum width that the pulse can be is about 26.2 us. The Pulse behavior is the default behavior for the marker event.
If you would like to generate a trigger signal longer than 26.2 us or want to control when during your signal generation when the trigger goes high and low, then you can use the Toggle behavior. You can configure the marker to be Toggle using the Marker:Output Behavior property. The Toggle behavior is useful when you need longer triggers or situations when you want to trigger other instruments on the rising edge of the trigger and on the falling edge of the trigger.
The LabVIEW shipping example niRFSG Marker Events.vi is a great starting point to show how to setup the marker events with the NI-RFSG driver in Script Mode.
