4 Triggering the Oscilloscope
Selecting Trigger Modes and Conditions
The trigger mode affects the way in which the oscilloscope
searches for the trigger. The figure below shows the conceptual
representation of acquisition memory. Think of the trigger event
as dividing acquisition memory into a pre-trigger and
post-trigger buffer. The position of the trigger event in
acquisition memory is defined by the time reference point and
the delay setting.
To select the Mode and Coupling menu
• Press the Mode/Coupling key in the Trigger section of the
front panel.
