TriggerScan
TriggerScan is a debugging tool 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:
1. 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.
2. 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 a currently acquired waveform and automatically builds a list of common trigger
setups used to find rare events.
PLEASE NOTE THE FOLLOWING:
x
You must acquire and display at least 3 cycles of a signal before running the Trainer.
x
You should run the Trainer if you want to change the trigger types or if you change the channel or signal.
1. Touch Trigger Trigger Setup from the menu bar.
2. On the Trigger dialog, click the TriggerScan tab.
3. Touch inside the Source data entry field and select a channel as the source for the training.
4. Touch the Trainer button.
5. On the TriggerScan Trainer Setup window, choose the types of triggers the Trainer should use to train
the system and then touch the Start Training button. The training begins. When it is complete, a list of
smart trigger setups is displayed in the Trigger List.
