Triggers
The MTS 5200 has a set of trigger controls that determine the exact instant the trace begins the
sweep across the screen. If a trigger is set at a specific voltage level, and the signal being
sampled achieves that trigger level voltage, then the MTS 5200 displays the signal. When
triggering, a T appears in the small box at the left of the trigger settings box at the bottom of the
touch screen display.
Normal Trigger
Normal trigger is a common trigger type and requires that you know the characteristics of the
signal you are trying to display. The MTS 5200 displays a signal that meets the trigger level at
the trigger position. If the signal does not meet the trigger level condition, the MTS 5200 does
not display a signal.
If you lose the trigger condition while viewing a signal, the signal display area freezes and
remains frozen until the signal reaches the trigger level. Normal trigger is the default trigger type
on select vehicle components when using the Component Selection procedure to view a
waveform such as fuel injector. Your last trigger type settings are saved in tester memory.
THE LAB SCOPE (SQUARE WAVE WITH & WITHOUT GLITCH)
Trigger Edge works in conjunction with the Trigger Level. Any signal that meets the Trigger Level
condition and your choice of trigger edge (Rising or Falling) is displayed at the Trigger Position.
The Rising Edge and Falling Edge buttons are available on the Trigger Setup menu as touch
screen display buttons. If Rising Edge is selected, only a rising signal that reaches the trigger
level and transitions to that voltage from a lower voltage meets the trigger conditions and is
displayed. A Falling Edge trigger works just the opposite.
