10.1 Overview of the Trigger Functions
･
The term "trigger" refers to a signal which is used to control the timing for
recording start or stop.
･
The term "triggering has occurred" refers to the state when such a signal has
activated recording start or stop.
･
Trigger parameters for the various functions are set using the TRIGGER
screen or the Waveform display screen.
･
The manual trigger is always activated when the MANU TRIG
key is pressed,
regardless of other trigger source settings.
･
If the trigger settings (trigger source parameters, pre-trigger) are changed
during recording, the measurement is restarted, using the new settings.
