Overview
The oscilloscope uses many waveform capture techniques that trigger on features
and conditions that you define. These triggers fall into two major categories:
Edge activated by basic waveform features or conditions such as a positive or
negative slope, and hold-off
SMART Trigger® sophisticated triggers that enable you to use basic or complex
conditions for triggering.
Use Edge Triggers for simple signals, and the SMART Triggers for signals with rare
features, like glitches.
This Getting Started Manual contains information on setting up the Edge Trigger.
Reference the online Help for information on setting up and using SMART
Triggers.
Trigger Terms
Trigger Delay - the amount of time that the oscilloscope trigger is adjusted
from a zero value. You can adjust the oscilloscope's trigger position from 0-
100% pre-trigger (left to right on the grid), or from 0-10,000 divisions (in time
units) of post-trigger.
Coupling – the type of signal coupling at the input of the trigger source: AC,
DC, LFREJ, HFREJ
Level – the threshold at which the trigger will occur, specified in volts.
Slope – the direction of the trigger voltage transition used for generating a
particular trigger.
