Chapter 5 To Trigger the Oscilloscope RIGOL
MSO7000/DS7000 User Guide 5-5
MSO7000/DS7000 provides three trigger modes: Auto, Normal, and Single. The
default is Auto.
In the trigger control area (Trigger) on the front panel, press Mode to quickly switch
the current trigger mode. The trigger mode is displayed at the upper-right corner of
the screen: A (Auto), N (Normal), and S (Single).
âš« Auto: In this trigger mode, if the specified trigger conditions are not found,
triggers are forced and acquisitions are made so as to display the waveforms.
This trigger mode should be used when the signal level is unknown or the DC
should be displayed as well as when forcible trigger is not necessary as the
trigger condition always occurs.
âš« Normal: In this trigger mode, triggers and acquisitions only occur when the
specified trigger conditions are 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.
âš« Single: In this trigger mode, the oscilloscope performs a single trigger and
acquisition when the specified trigger conditions are 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 currently displayed waveform, and the subsequent waveform data will not
overwrite the current waveform). After a single trigger mode is initiated, the
operating status of the oscilloscope is in "STOP" state.
Note: In "Normal" and "Single" trigger modes, pressing Force can generate a
trigger signal forcibly.
In addition, you can enable the touch screen to set the trigger mode. Enable the
touch screen and tap the trigger setting label
at the upper-right
corner of the screen. Then the following window is displayed. Tap to select "Auto",
"Normal", or "Single" as the trigger mode.
