Programming trigger synchronization and delays
The previous transient examples were programmed to respond to immediate triggers. However, delayed and phase synchronized triggers can also be programmed as shown in the following examples.
No delay; no phase synchronization

When these commands are sent, the voltage amplitude changes immediately upon the receipt of a trigger.

When these commands are sent, the voltage amplitude changes at the next 90 degree phase angle that occurs following the receipt of a trigger.
