Setting Trigger Level and Slope
The Connect-and-View™ function enables hands-off
triggering to display complex unknown signals.
When your test tool is in manual range, do the following:
MANUAL
AUTO
Perform an auto set. AUTO appears
at the top right of the screen.
Automatic triggering assures a stable display of virtually
any signal.
From this point, you can take over the basic trigger
controls such as level, slope and delay. To optimize trigger
level and slope manually, do the following:
1
TRIGGER
Display the TRIGGER key labels.
2
F2
Trigger on either positive slope or
negative slope of the chosen
waveform.
In Dual Slope Triggering ( X ) the
test tool triggers on both positive
slope and negative slope.
3
F3
Enable the arrow keys for manual
trigger level adjustment.
Figure 28. Screen with all Trigger Information
4 Adjust the trigger level.
Observe the trigger icon that indicates the trigger
position, trigger level, and slope.
At the bottom of the screen the trigger parameters are
displayed (See Figure 28). For example,
means that input A is used as the trigger source with a
positive slope.
When a valid trigger signal is found, the trigger key will be
lit and the trigger parameters appear in black.
When no trigger is found, the trigger parameters appear in
gray, ands the key light will be off.
