Cross-Arming Trigger Examples
To capture the waveform of a glitch using the oscilloscope (oscilloscope option only)
The following setup uses the triggering capability of the timing
analyzer and the acquisition capability of the oscilloscope.
1Set up a timing analyzer. Go to the timing analyzer’s Format
menu and set the Timing Acquisition Mode to Half Channel
500 MHz.
2Go to the timing analyzer’s Trigger menu.
3Select an Edge term. Then assign glitch detection “*” to the
channels of interest represented by the Edge term.
4Go to the Arming Control menu. Set the Scope Arm In to
Analyzer.
5Select Group Run in the Analyzer Arm In menu.
6Go 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.
NOTE: A timing analyzer can trigger on a glitch and capture it, but a timing analyzer
doesn’t have the voltage or timing resolution to disp lay the glitch in detail. An
oscilloscope can display a glitch waveform with fine resolution, but cannot
trigger on glitches, combinations of glitch es, or sophisticated patterns
involving many channels.
