Glitch Trigger Mode and Commands
Use the Glitch Trigger Mode to find pulses in a waveform that are
narrower than the rest of the pulses in the waveform.
To look for pulses that are wider than the other pulses in your waveform,
you should use the pulse width trigger. Pulse width trigger is in the
Advanced trigger menu under Violation trigger.
The oscilloscope identifies a glitch trigger by looking for a pulse that is
narrower than other pulses in your waveform. You specify the width that
the pulse must be narrower than, and the pulse polarity (positive or
negative) that the oscilloscope should consider to be a glitch. For a
positive glitch, the oscilloscope triggers when the falling edge of a pulse
crosses the trigger level. For a negative glitch, the oscilloscope triggers
when the rising edge of the pulse crosses the trigger level.
Source
Use this control to select the oscilloscope channel used to trigger the
oscilloscope.
Level
Use the Level control to set the trigger level through which the glitch
must pass before the oscilloscope will trigger.
When setting the trigger level for your waveform, it is usually best to
choose a voltage value that is equal to the voltage value at the mid point
of your waveform. For example, if you have a waveform with a minimum
value of 0 (zero) volts and a maximum value of 5 volts, then 2.5 volts is
the best place to set your trigger level. The reason this is the best choice
is that there may be some ringing or noise at both the 0-volt and 5-volt
levels that can cause false triggers.
When you adjust the trigger level control, a horizontal dashed line with
a T on the right-hand side appears, showing you where the trigger level
is with respect to your waveform. After a period of time the dashed line
will disappear. To redisplay the line, adjust the trigger level control
again, or activate the Trigger dialog. A permanent icon with arrow
(either T, T
L
, or T
H
) is also displayed on the right side of the waveform
area, showing the trigger level.
Polarity
Use the Positive control to look for positive glitches. Use the Negative
control to look for negative glitches.
