8.4 Setting the Trigger System

The Trigger defines the time when the acquisition of data and display of waveform. If it is set
correctly, the trigger can turn an unstable display into a significant waveform.

When starting the acquisition of data, the oscilloscope collects sufficient data to draw the
waveform at the left side of the triggering point. With waiting for the triggering condition, the
oscilloscope is gathering data continuously. After a trigger is detected, the oscilloscope gathers
enough data continuously to draw the waveform at the right side of the triggering point.

To make a trigger mode setting, do the following:

1.

Press the

MENU

key and the function menu appears at the right of the screen.

2.

Press the
