Term Glossary
Trigger modes: There are three kinds of trigger modes available for this oscilloscope-
auto, normal and single shot.
Automatic trigger mode: In this mode, the oscilloscope can acquire a Waveform
without any triggering condition detected. It will be triggered automatically after waiting a
specified period of time. When an invalid trigger is sensed the oscilloscope cannot keep
the Waveform in phase.
Normal trigger mode: In this mode the oscilloscope cannot acquire the Waveform until it
is triggered. If there is no trigger, the oscilloscope will display the original Waveform
without new Waveforms being captured and/or displayed.
Single shot mode: In this mode the oscilloscope will detect a trigger and capture a
Waveform each time the operator presses the RUN/STOP key.
