NOTE
Triggering occurs, since the system judges that
the period deviates from the specified range.

Settings on the Waveform display screen
Restriction:
The trigger slope and reference voltage value cannot be
set.
To set numerical value by using the Jog and Shuttle
controls, press VALUE key.
The selected window is not displayed in the pre-trigger
setting.
Since a trigger filter is not prepared for the period trigger, triggering may
mistakenly occur due to noise (see the figure below).
To prevent such an event, use an appropriate low-pass filter.
