Edge Trigger with Holdoff by Events (in this example, two events). The bold edges on the trigger source indicate
that a positive slope has been selected. The broken, upward-pointing arrows indicate potential triggers, while the
bold ones show where triggers actually occur after the holdoff expires.

Edge Trigger on Simple Signals
The instrument 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.
Control Edge Triggering
Horizontal: Turn the Delay knob in the HORIZONTAL control group to adjust the trigger's
horizontal position. Or, touch inside the Delay field in the timebase setup dialog and enter a value,
using the pop-up keypad.
The trigger location is shown by a marker below the grid
Post-trigger delay is indicated by a left-pointing arrow below-left of the grid
