Triggerscan - Teledyne HDO9000 Operator's Manual

TriggerScan

TriggerScan is a debugging tool that helps you quickly discover waveform anomalies by automating
the process of building triggers designed to find rare events in an acquisition. TriggerScan:
Trains the system by looking at normal acquired waveforms. During the training, TriggerScan
l
analyzes the waveforms to determine what waveforms normally look like. Using this
information, it generates a list of smart triggers to isolate abnormal situations.
Loads the trigger setups from the Trainer and cycles them. As triggers occur, they are overlaid
l
on the screen. All acquisition settings are preserved, and you can use other tools to find the
root cause of these anomalies such as WaveScan, Histograms, etc.
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 open the TriggerScan tab.
2. Touch the Trainer button.
3. On the TriggerScan Trainer pop-up, choose the Source channel on which to train and trigger,
and select all the
4. Touch the Start Training button. When training is complete, a list of smart trigger setups is
displayed in the Trigger List.
Modifying Trigger List
Follow these steps to change the triggers created by TriggerScan. Once you have finalized the Trigger
List, you are ready to start scanning.
1. Choose Trigger > Trigger Setup... from the menu bar, then open the TriggerScan tab.
2. Make any of the following modifications to the Trigger List:
Add new trigger: touch the Trigger descriptor box and set up the new trigger as desired
l
on the Trigger dialog. Then, back on the TriggerScan dialog, touch the Add New button to
append the new trigger to the Trigger List.
