Note:
Trigger Hold-off can stabilize complex waveforms. Hold-off time is the oscilloscope's
waiting period before starting a new trigger. During Hold-off, oscilloscope will not
trigger.

LOSSARY OF ERMS
• Hold-off time: Programmable time period between trigger events (100ns default).
• Trigger modes: There are three trigger modes: Auto (acquires signal continuously),
Normal (acquires signal when trigger conditions are met) and Single (manually
triggers the signal).
• Automatic trigger mode: In this mode, the oscilloscope can acquire a waveform
without a triggering condition
• Normal trigger mode: In this mode, the oscilloscope cannot acquire the waveform
until it is triggered. When no trigger is present, the oscilloscope will display only the
original waveform; no new waveforms can be captured until a trigger is detected.
• Single mode: In this mode, the oscilloscope will detect a trigger and capture a
waveform each time the user presses the RUN/STOP key.
