[ 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 voltage 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.
Example for Period Trigger
In order to cause triggering when the signal as shown in the figure below
leaves the period range of 0.9 to 1.1 s, the following settings are made:
Lower limit of the period: 900 ms, Upper limit of the period: 1.1 s,
Reference voltage: 0.000 V
