Triggers and When to Use Them
Choosing the Right Trigger
Your oscilloscope offers many distinctive and useful
techniques for triggering on and capturing data. These
range from the simple Edge triggers to the advanced
SMART Trigger types, which trigger on multiple inputs.
Three triggering modes are available: AUTO, NORM and SNGL.
Additionally, STOP enables the acquisition process to be
aborted. All are directly accessible by pressing the respective
front-panel buttons. (See Chapter 6.)
Modifying Trigger Settings Trigger adjustments are made directly using the front-panel controls
and with the trigger menus.
Rotating — for example — causes the scope to adjust the
trigger level of the highlighted trace.
Pressing accesses advanced trigger operations, such as
changing the glitch width or the hold-off timeout, which are
changed via the TRIGGER SETUP menu group (Fig. 8–1). Once
the trigger configuration has been modified, changes are stored
internally in a non-volatile memory.
