Triggering Position of the Period Trigger
The system monitors the period of the signal that crosses
the set reference level.
When the monitored period deviates from the set range,
triggering occurs. The trigger position is determined by the
set period range and the measurement signal period.
Signal with a period to be measured that is smaller than
lower limit of the period trigger (trigger slope:
):
When the signal crosses the reference level at the set trigger
slope before the lower limit of the set period range appears
on the screen, the intersection is always defined as the
triggering position.
Signal with a period to be measured that is larger than the
upper limit of the period trigger (trigger slope:
):
When the upper limit of the set period range appears on the
screen before the signal crosses the reference level at the set
trigger slope, the upper limit is defined as the triggering
position. The triggering position is determined by the
position of the upper limit in the period range, as shown in
the figure above.
