Issue Details

I am using a PXI device and I want to generate a waveform after a trigger, after a specified amount of time. How do I add a delay after a trigger on LabVIEW ?

Solution

To apply a time delay between a trigger and your signal generation function, you can add the delay function and the waveform generation function inside a sequence structure placed after the trigger.

As you can see in the figure below, the waveform generation function will start after the "wait" function in the sequence structure.

Additional Information

The time delay configured in LabVIEW does not take into account the program execution delays that may occur between the trigger and the signal generation.
If you want more precise delays, you must use real-time applications.
