TriggerScan
TriggerScan is a debugging tool (available for any trigger type) that helps you quickly find rare waveform
glitches and anomalies. With TriggerScan, you can build a list of trigger setups to look for rare events and
automatically sequence through each one. TriggerScan can use any type of trigger setup available
including edge, width, and qualify as well as Smart Triggers (such as, glitch and runt triggers).
TriggerScan automates two key processes in triggering rare events:
l
Trains
the system by looking at normal acquired waveforms. During the training, the oscilloscope
analyzes the waveforms to determine what waveforms normally look like. Using this information, it
generates a list of smart trigger setups to trigger on abnormal situations.
l
Loads
the smart trigger setups from the Trainer and cycles through these. As triggers occur, they
are overlaid on the screen. All acquisition settings are preserved and you can use all the functions
of the oscilloscope to find the root cause of these anomalies including, WaveScan, Histograms, and
advanced analysis.
Training TriggerScan
The TriggerScan Trainer inspects the current acquisition and automatically builds a list of trigger setups
that could potentially be used to find events of interest.
NOTE
: Run the Trainer if you want to change the trigger types or if you change the channel or signal. You
must acquire and display at least 3 cycles of a signal before running the Trainer.
1. Touch
Trigger
→
Trigger Setup...
from the menu bar, then touch the
TriggerScan
tab.
2. Touch the
Trainer
button.
3. Choose the
Source
channel on which to train, and select all the
trigger types
you want to set up.
4. Touch the
Start Training
button. The training begins. When it is complete, a list of smart trigger setups
is displayed in the Trigger List.
Modify Trigger List
The Trigger List displays a list of of the triggers created by the Trainer. Follow these steps to add or
remove triggers, or update their individual setups. Once you have made any changes to the Trigger List,
you are ready to start scanning.
1. If not already there, choose
Trigger
→
Trigger Setup...
from the menu bar, then touch the
TriggerScan
tab.
2. Make any of the following modifications to the Trigger List:
l
To add a new trigger setup to the list, touch the
Trigger
tab and set up the new trigger as desired
on the
Trigger
dialog. Then, back on the
TriggerScan
dialog, touch the
Add New
button to append
the new trigger to the
Trigger List
