To analyze the signal in roll mode, you can use:
Zoom
Automatic measurements
Cursor measurements
Mathematics
You can also save the waveform data. Saving stops the acquisition. Acquisition is
resumed when the data is written.
3.6 Trigger
Triggering means to capture the interesting part of the relevant waveforms. Choosing
the right trigger type and configuring all trigger settings correctly allows you to detect
various incidents in signals.
A trigger occurs if the trigger conditions are fulfilled. The instrument acquires continu-
ously and keeps the sample points to fill the pretrigger part of the waveform record.
When the trigger occurs, the instrument continues acquisition until the posttrigger part
of the waveform record is filled. Then it stops acquiring and displays the waveform.
When a trigger is recognized, the instrument does not accept another trigger until the
acquisition is complete.
Trigger conditions include:
Source of the trigger signal (channel)
Trigger type and its setup, including one or more trigger levels
Trigger mode
In addition, the horizontal position of the trigger point and the reference point are
important to display the interesting part of the signal. See Chapter 3.3, "Horizontal
Setup", on page 45.
The trigger level and position are marked in the grid. The markers have the color of the
trigger source. Information on the most important trigger settings is shown in the upper
information bar.

To adjust all trigger settings, press the [SETUP] key.
To adjust the trigger level, do one of the following:
Drag the trigger level marker on the right side of the display to the required
position.
Press the [LEVEL] key and turn the wheel.
If the trigger type has two trigger levels, press the [LEVEL] key again to toggle
the upper and lower levels. Alternatively, press the wheel.
Press the [SETUP] key. Select "Trigger Level", and enter the level value.
