Triggering On A Waveform; Setting Trigger Level And Slope - Fluke 125 User Manual

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. You can
setup 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 2-15.)
For 3 phase power measurements the trigger
settings are fixed.
