Modes

You can select the Auto or the Normal trigger mode to define how
the oscilloscope acquires data when it does not detect a trigger
condition. See page 9- - 38.
To perform a single sequence acquisition, push the SINGLE SEQ
button.

Coupling

You can use the Trigger Coupling option to determine which part of
the signal will pass to the trigger circuit. This can help you attain a
stable display of the waveform.
To use trigger coupling, push the TRIG MENU button, select an
Edge or Pulse trigger, and select a Coupling option.
NOTE. Trigger coupling affects only the signal passed to the trigger
system. It does not affect the bandwidth or coupling of the signal
displayed on the screen.
To view the conditioned signal being passed to the trigger circuit,
push and hold down the TRIG VIEW button.

Position

The horizontal position control establishes the time between the
trigger and the screen center. Refer to Horizontal Scale and Position;
Pretrigger Information on page 3- - 8 for more information on how to
use this control to position the trigger.
