To capture the waveform of a glitch
The following setup uses the triggering capability of the timing analyzer and
the acquisition capability of the oscilloscope.
1
Set up a timing analyzer. Go to the timing analyzer’s Format menu
and set the Timing Acquisition Mode to Glitch Half Channel 125 MHz.
Glitch mode only allows you to use one pod of a pod pair at a time. If the
wrong pod is active, toggle by selecting the Pod field.
2
Go to the timing analyzer’s Trigger menu.
3
Select an Edge term. Then assign glitch detection "*" to the channels
of interest represented by the Edge term.
4
Go to the Arming Control menu. Set the Scope Arm In to Analyzer.
5
Select Group Run in the Analyzer Arm In menu.
6
Go to the Scope Trigger menu, and set Mode to Immediate.
If you have trouble capturing the glitch waveform on the oscilloscope, try
adjusting the skew in the Arming Control menu, so the oscilloscope triggers
earlier.
A timing analyzer can trigger on a glitch and capture it, but a timing analyzer
doesn’t have the voltage or timing resolution to display the glitch in detail. An
oscilloscope can display a glitch waveform with fine resolution, but cannot
trigger on glitches, combinations of glitches, or sophisticated patterns involving
many channels.
