Adjust Trigger Delay - Teledyne T3DSO2000 Series User Manual

Adjust Trigger Delay

Turn the Position Knob on the front panel to adjust the trigger delay of the waveform.
During the modification, waveforms of all the channels will move left or right and the
trigger delay message at the upper-right corner of the screen changes accordingly. Press
the knob to quickly reset the trigger delay.
Changing the delay time moves the trigger point (solid inverted triangle) horizontally and
indicates how far it is from the time reference point. These reference points are indicated
along the top of the display grid.
All events displayed left of the trigger point happened before the trigger occurred. These
events are called pre-trigger information, and they show events that led up to the trigger
point.
Everything to the right of the trigger point is called post-trigger information. The amount of
delay range (pre-trigger and post-trigger information) available depends on the time/div
selected and memory depth.
The position knob works (in the Normal time mode) while acquisitions are running or when
they are stopped.
