Name Definition
Glitch positive Triggering occurs if the oscilloscope detects positive spike
widths less than the specified glitch time.
Glitch negative Triggering occurs if the oscilloscope detects negative spike
widths less than the specified glitch time.
Glitch either Triggering occurs if the oscilloscope detects positive or
negative widths less than the specified glitch time.
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.
