Set trigger system
The trigger determines when the oscilloscope starts acquiring data and displaying the waveform. Once set
correctly, the trigger can convert a fluctuating display into a meaningful waveform.
When the oscilloscope starts acquiring data, it records enough data to display the waveform to the left of the
trigger point. The oscilloscope continues to record data while waiting for a trigger condition. When a trigger
is detected, the unit continuously records enough data to display the waveform to the right of the trigger point.
The trigger control area consists of a 1 rotary knob and 2 menu buttons.
TRIG LEVEL: This knob sets the trigger level. When you press the knob, the level is reset to zero.
Force: Press this button to create a trigger signal. This function is primarily used with the trigger
modes "Normal" and "Single".
Trigger Menu: The button calls up the trigger control menu.
Single trigger

trigger (Single, Alt, Logic, Bus) in the lower menu. The trigger type can then be selected in the right-hand
screen menu under Type.

Logic Trigger: Triggers a signal according to the conditions of the logic ratio
Bus Trigger: Sets bus timing trigger
