Page 22 3 Horizontal Axis (Time Axis) Roll mode display In roll mode, the displayed waveform is not updated using triggers. Rather, the oldest data is deleted as new data is acquired, and the waveform flows from the right to the left of the screen. This mode is useful for observing low-frequency signals or signals that change slowly.
Page 23: Triggering
4 Triggering Triggers are events used to display waveforms. A trigger occurs when the specified trigger condition is met, and a waveform is displayed on the screen. Trigger mode (Trigger Mode) The trigger mode determines the conditions for updating the displayed waveforms. There are five trigger modes. Auto Mode (Auto) If the trigger conditions are met within a timeout period, the instrument updates the displayed waveforms on each trigger occurrence.

You can select from one of the settings below. You cannot use HF rejection when the trigger source is set to LOGIC, EXT, or LINE.
Page 29 4 Triggering • If you change the trigger position when waveform acquisition is stopped, the instrument re-displays waveforms using the new position. • The time values of cursor measurements are based on the trigger position. If you change the trigger position, the measured values will change (except during roll mode display).
Page 30: Edge Or Trigger [Enhanced]
