In example
•
, the output transient is triggered immediately at the receipt of the
trigger signal. In example
‚
, a delay time of approximately 16.7 milliseconds
elapses between the occurrence of the trigger and the start of the output transient.
In example
ƒ
, the trigger source is programmed for phase synchronization, which
means that the transient occurs at the first occurrence of the specified phase angle
after the trigger signal is received. Example
„
describes phase synchronization on
three-phase sources.
Note that phase synchronization is referenced to an internal phase signal. The
output of the unit is normally offset by 0º with respect to this internal reference.
Because synchronized transient events always occur with respect to the internal
reference, the output will normally be in phase with the value programmed for phase
synchronization. (The Phase command can be used to change the offset of the
output with respect to the internal phase reference.)
