Trigger Modes
The oscilloscope provides two trigger modes: Auto Trigger Mode
and Normal Trigger Mode.
Auto Trigger Mode
In Auto trigger mode, the oscilloscope automatically triggers
and captures waveforms when you click on the Run button.
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). Since there are no edges on which
to trigger, Auto trigger mode is used to display a DC signal.
Normal Trigger Mode
If you only want to acquire specific events as specified by the
trigger settings, use
Normal
trigger mode. If you click on the
Run button when the oscilloscope is in Normal trigger mode, a
trigger must be detected before an acquisition can be
completed.
Trigger Source
There are three types of trigger source: Channel 1, Channel 2
and External. The external trigger source can be used as a
source in several trigger types. The trigger source will be the
analog channel available on your oscilloscope.
