14 Press the Level Select softkey until it indicates High; then turn the Trigger
Level knob to set the upper (high) trigger threshold level to the
approximate 90% level. Note that you can also drag the T
H
marker on
the left side of the display.
15 Tap the “< >” softkey to select “>”.
16 Tap the Time softkey twice, which opens the keypad. Set the violation
time to > 100 ns.
Your scope should now be triggering on just rising edges of the input
signal that have rise times in excess of 100 ns as shown in Figure 33. In
addition to triggering on Rise/Fall Time violation edges, the Agilent
4000 X-Series oscilloscopes can also perform Search & Navigation to find
multiple edge speed violation conditions, regardless of the specific trigger
setup condition.
17 Set the scope’s timebase to 200.0 µs/div.
18 Press [Run/Stop] to stop repetitive acquisitions (the [Run/Stop] key
should turn red).
19 Press the [Search] front panel key.
20 Tap the Search Edge softkey and select the Rise/Fall Time search mode.
