Hi,  
I noticed that there is a delay of about 0.5-1 second when turning off/on the output of the waveform generator via the Matlab API. I have used both generate\_waveform(’ type’, `Off`), as well as enable\_output with the arbitrary waveform generator. Is there any way to switch off an output with a lower delay (order of ms)?

The application I have in mind is a conditional trigger, where the waveform generator generates a pulse train that stops as soon as an input signal stays at a certain level, measured by the oscilloscope.  
Best,  
Stephan
