Trigger Controls
Introduction
The trigger defines when a signal is acquired and stored in memory. For a repetitive signal, a trigger is
required to stabilize the display.
There is a front-panel control to set the trigger level and a button to force the oscilloscope to trigger. The
Trigger menu offers different trigger types and allows you to set the conditions of the trigger.
