Triggering on a Waveform
Triggering tells the test tool when to begin displaying the
waveform. You can select which input signal should be
used, on which edge this should occur, and you can
define the condition for a new update of the waveform.
Finally you can tell the test tool to trigger on video signals.
The bottom line of the waveform area identifies the trigger
parameters being used. Trigger icons on the screen
indicate the trigger level and slope. (See Figure 1-16.)
Setting Trigger Level and Slope
Perform an AUTO SET.
For quick operation, use the AUTO SET key to
automatically trigger on nearly all signals. To optimize
trigger level and slope manually, do the following:
Press until you have left any open
menu.
Enable the arrow keys for Trigger
Level and Slope adjustment.
Adjust the Trigger Level
continuously. Observe the trigger
icon on the second time division
line indicates the trigger level.
Trigger on either positive Slope or
negative Slope of the chosen
waveform.
