RIGOL Chapter 5 To Trigger the Oscilloscope
5-4 MSO2000A/DS2000A User’s Guide
Normal:
In this trigger mode, the oscilloscope triggers and samples data only when the
specified trigger condition is found.
This trigger mode should be used when the signal is with low repetition rate or only
the event specified by the trigger setting needs to be sampled as well as when auto
trigger should be prevented to acquire stable display.
Single:
In this trigger mode, the oscilloscope performs a single trigger and acquisition when
the specified trigger condition is found and then stops.
This trigger mode should be used when you need to perform a single acquisition of
the specified event and analyze the acquisition result (you can pan and zoom the
waveform currently displayed and the subsequent waveform data will not overwrite
the current waveform).
Note: In Normal and Single trigger modes, pressing FORCE can force a trigger.
