More about the trigger system

In the previous examples, a front panel trigger is used to generate the output transients. The trigger is shown occurring at 270 degrees but actual triggers may occur at any phase. Delay and phase synchronization however, will occur as programmed.

Note that trigger system used in the ac source provides great flexibility in generating triggers. The following figure is a simplified model of the trigger system. A complete discussion of the capabilities of the trigger system is found in the ac source Programming Guide.
