Press [RUN/STOP] and wait for a signal that meets
the trigger condition. If any signal reaches the set
trigger level, the system will sample once and display
it on the screen. By using this function you can easily
acquire any occasional event. For example, when a
sudden glitch of relatively big amplitude is acquired :
set the trigger level to just higher than the normal signal
level. Press [RUN/STOP] and begin waiting. When a
glitch occurs, the machine will automatically trigger
and record the waveform immediately before and after
triggering. By turning the horizontal displacement key,
you can change the trigger position horizontally to
achieve negative delay trigger of various lengths for
easy observation of waveform occurring before the
glitch.
