This is the critical part of the oscilloscope setup to capture the relevant part of the
waveform.
● Trigger mode: "Trigger mode" on page 85
● Trigger position: chapter 3.3.5, "Trigger Position", on page 83
Optional settings are:
● Noise rejection settings: chapter 3.3.3, "Noise Reject", on page 79
● Trigger sequence, a combination of two trigger events: chapter 3.3.4,
"Sequence", on page 80

Setup", on page 49
3.3.1 Events
The setup of the trigger type is the most important part of the trigger definition. It deter-
mines the method to identify specific signal phenomena. In principle, all trigger types are
available for all events in a trigger sequence, that is, you can combine different types with
A-, B-, and R-event. The instrument checks the trigger settings for compatibility and fea-
sibility and disables settings that do not fit the previous settings in the sequence.
Make sure that the correct trigger tab is selected on the left before you enter the settings.
The settings in the "Event" tab are:
● Basic Trigger Settings.............................................................................................58
● Edge........................................................................................................................62
● Glitch.......................................................................................................................63
● Width.......................................................................................................................64

3.3.1.1 Basic Trigger Settings
The basic trigger settings are the trigger source and the trigger type, including the trigger
level. These settings are specific for each event in a trigger sequence, that is, specific for
A-, B- and R-events. For the trigger source, the current ground/coupling settings are
displayed, filtering is also possible.
