Name Definition
Runt positive Triggering occurs if the oscilloscope detects a positive pulse
that crosses one threshold going positive but fails to cross a
second threshold before recrossing the first going negative.
Runt negative Triggering occurs if the oscilloscope detects a negative
going pulse that crosses one threshold going negative but
fails to cross a second threshold before recrossing the first
going positive.
Runt either Triggering occurs if the oscilloscope detects a positive or
negative going pulse that crosses one threshold but fails to
cross a second threshold before recrossing the first.
Width positive Triggering occurs if the oscilloscope finds a positive pulse
with a width between, or optionally outside, the user-speci-
fied lower and upper time limits.
Width negative Triggering occurs if the oscilloscope finds a negative pulse
with a width between, or optionally outside, the user-speci-
fied lower and upper time limits.
Slew Positive Triggering occurs if the oscilloscope detects a positive
pulse edge that after first crossing the lower threshold then
crosses the upper threshold. The pulse must travel
between the two levels at a rate faster or slower than (user
specifies) the user-specified slew rate for triggering to
occur.
Slew Negative Triggering occurs if the oscilloscope detects a negative
pulse edge that after first crossing the upper threshold then
crosses the lower threshold. The pulse must travel between
the two levels at a rate faster or slower than (user
specifies) the user-specified slew rate for triggering to
occur.
Slew either Triggering occurs if the oscilloscope detects a positive or
negative pulse edge that first crosses one threshold and
then crosses the other threshold. The pulse must travel
between the two levels at a rate faster or slower than (user
specifies) the user-specified slew rate for triggering to
occur.
When you select the pulse class Glitch, the oscilloscope will trigger on a pulse
narrower (or wider) in width than some specified time. To set up for glitch
triggering, do the following procedures.
Select Glitch Triggering. Press TRIGGER MENU ➞ Type (main) ➞ Pulse
(pop-up) ➞ Class (main) ➞ Glitch (pop-up).
