Reference
Push this knob to automatically sets the Trigger Level to be about halfway
between the minimum and maximum voltage levels. This can frequently help to
quickly stabilize a waveform.
Force Trig Button.
Use the
Force Trig
button to complete the waveform
acquisition whether or not the oscilloscope detects a trigger. This is useful for
single sequence acquisitions and Normal trigger mode. (In Auto trigger mode,
the oscilloscope automatically forces triggers periodically if it does not detect a
trigger.)
Trigger View.
Push the
Trigger Menu
button for more than 1.5 seconds to
enable the Trigger View mode and display the conditioned trigger signal on the
oscilloscope. You can use this mode to see the following types of information:
Effects of the Trigger Coupling option
AC Line trigger source (Edge Trigger only)
Signal connected to the Ext Trig BNC
Holdoff.
You can use the Trigger Holdoff function to produce a stable display of
complex waveforms, such as pulse trains. Holdoff is the time between when
the oscilloscope detects one trigger and when it is ready to detect another. The
oscilloscope will not trigger during the holdoff time. For a pulse train, you can
adjust the holdoff time so the oscilloscope triggers only on the
fi
rst pulse in the
train.
To use Trigger Holdoff, push the
