occasional violations. Uniquely triggering on edge speed violation signals
can be accomplished on Agilent’s 3000 X- Series oscilloscopes using the
Rise/Fall Time
triggering mode.
11
Press the
[Trigger]
front panel key; then turn the Entry knob to select
the
Rise/Fall Time
trigger type.
12
Press the
Level Select
softkey to select
Low
.
13
Turn the
Trigger Level knob
to set the lower trigger threshold level to the
approximate 10% level. Note that you can visually use the lower
measurement threshold marker as a good indication as to where the
approximate 10% level is located.
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 visually use the upper
measurement threshold marker as a good indication as to where the
approximate 90% level is located.
15
Press the “
< >
” softkey to select “
>
”.
16
Press the
Time
softkey; then turn the Entry knob to 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
addition to triggering on Rise/Fall Time violation edges, the Agilent
Figure 33 Using Rise/Fall Time triggering to trigger on violation edge speeds.
