Choosing Auto Trigger Mode or Normal Trigger Mode

• Press the [Mode/Coupling] key in the Trigger section of the front panel.
If you press [Run] when the oscilloscope is in Normal trigger mode, a trigger must be
detected before an acquisition can complete. No waveform will be displayed unless the
trigger condition is met.
In Auto trigger mode, the oscilloscope automatically triggers and captures waveforms
when you press [Run].
In many cases, a triggered display is not needed to check signal levels or activity. For
these applications, use Auto trigger mode (which is the default setting). If you only want
to acquire specific events as specified by the trigger settings, use Normal trigger mode.
In some cases, such as when triggering on a slow serial signal (for example, I
CAN, LIN, etc.) it may be necessary to select the Normal trigger mode to stabilize the
display by preventing the oscilloscope from Auto-triggering.
You can select the trigger mode by pressing the [Mode/Coupling] key, then the Mode
softkey.
1 Press the [Mode/Coupling] key.
2 Press the Mode softkey, then select Normal or Auto.
• Normal — displays a waveform when the trigger conditions are met, otherwise the
oscilloscope does not trigger and the display is not updated.
• Auto — is the same as Normal mode, except it forces the oscilloscope to trigger if
the trigger conditions are not met.
