> [Trigger] > [Common]
START
Starts recording when the instrument is triggered, and stops the recording after the
instrument has acquired the recording-length waveforms.
A displayed trigger point may lag behind the actual trigger point by some samples between one and
four when measuring modules include any one of the following modules: Model U8975 4ch Analog

Starts recording
Starts recording when the instrument is triggered.
Stops the recording
When the mode is
set to [Single]
Stops the recording after the instrument has acquired the recording-length data.
When the mode is
set to [Repeat]
Starts recording, stops the recording after the instrument has acquired the
recording-length data, and then waits for a trigger.
When triggered again, starts recording, stops the recording after the instrument
has acquired the recording-length data, and then waits for a trigger (repeats this
sequence).
Example of trigger timing
