Keysight Models 6811C, 6812C, and 6813C Quick Start Guide 53
Trigger delay; 90 degrees phase synchronization
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.

When these commands are sent, the voltage amplitude changes at the
next 90 degree phase angle that occurs after the .0167 second delay has
expired, following the receipt of a trigger.
