2.8 Trigger Position
The total sample buffer is 3000 points long. The acquisition can be triggered in Auto and Norm mode from the input waveform.
By adjusting the trigger position slider, you can make the trigger position in the buffer earlier or later in time. This is known as pre and post triggering.
Trigger position is adjustable in
2.9 Trigger Delay
Like the trigger position setting, the trigger delay allows an amount of time to pass after the trigger instant, before the acquisition stores the sample data into the buffer. This allows you to see events that happen some time after the trigger.
The delay is adjustable in steps of the sample interval, from 0 to 65535 steps. Adding trigger delay when using slow timebase settings further slows the time between successive sweeps.
When delayed trigger is used, the trigger mark on the plot shows a “<” symbol.
15By definition, RIS mode needs repetitive waveforms so pre or post trigger has no relevance.
