Glitch positive
Triggering occurs if the oscilloscope detects positive spike
widths less than the specified glitch time.
widths less than the specified glitch time.
Glitch negative
Triggering occurs if the oscilloscope detects negative spike
widths less than the specified glitch time.
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.
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.
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.
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.
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.
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.
with a width between, or optionally outside, the user-speci-
fied lower and upper time limits.
