4.9 Recording Using Specific Conditions (Trigger Function)
110
You can apply specific conditions to start and stop measurement.
In the case of [Highspeed] , only the condition for starting measurement can be
applied. When these specific conditions are applied for measurement, the trigger
function is used.
Triggering is the process of controlling the start and stop of
recording by specific signals or conditions (criteria). When
recording is started or stopped by a specific signal, we say the
trigger is "applied" or "triggering occurs."
In this manual, indicates a “trigger point”, as the time at
which a trigger is applied.
Signals that can be used for triggering (trigger sources) are as follows.
You can set the condition for each channel on the [CH] screen, and the trigger set-
tings for all channels on the [Trig] screen.
