Using Trigger Delay or Pre-trigger

Using Trigger Delay or Pre-trigger

You can begin to display the waveform some time before or after the trigger point has been detected. Initially, you have 2 divisions of pre-trigger view (negative delay).

To set the trigger delay, do the following:

Hold down to adjust the trigger delay.

Observe that the trigger icon on the screen moves to show the new trigger position. When the trigger position moves left off of the screen, the trigger icon changes into to indicate that you have selected a trigger delay.

Moving the trigger icon to the right on the display gives you a pre-trigger view.

In case of a trigger delay, the status at the bottom of the screen will change. For example:

This means that input A is used as the trigger source with a positive slope. The 500.0 ms indicates the (positive) delay between trigger point and waveform display.

When no trigger is found, the trigger parameters appear in gray.
