A trigger setup tells the oscilloscope when to acquire and display data. For
example, you can set up to trigger on the rising edge of the analog channel 1 input
signal.
You can adjust the vertical level used for analog channel edge detection by
turning the Trigger Level knob.
In addition to the edge trigger type, you can also set up triggers on pulse widths,
patterns, and video signals.
You can use any input channel or the “External Trigger Input" on page 152 BNC as
the source for most trigger types.
Changes to the trigger setup are applied immediately. If the oscilloscope is
stopped when you change a trigger setup, the oscilloscope uses the new
specification when you press [Run/Stop] or [Single] . If the oscilloscope is running
when you change a trigger setup, it uses the new trigger definition when it starts
the next acquisition.
You can use the [Force Trigger] key to acquire and display data when triggers are
not occurring.
You can use the [Mode/Coupling] key to set options that affect all trigger types (see
Chapter 11 , “Trigger Mode/Coupling,” starting on page 147).
