Using a Window Trigger
An input signal level “window” within which recording will (or will
not) occur can be defined by upper and lower threshold levels.
You can select whether measurement starts or stops when the
input signal level enters (In) or exits (Out) of this window.
Upper and lower thresholds can be verified in the monitor or on
the Waveform screen. When scaling is enabled, the scaled
threshold values are displayed.
Make trigger settings on the
[CH] screen of the displayed chan-
nel.
