Flatness
- A delay compensation similar to eye diagram, this
selection provides a flat frequency response and group delay. It
provides the fastest rise time.

Trigger Overview
Triggering is the way an oscilloscope selects an exact moment in time on a
signal to then be shown on the screen. If the pattern of a signal happens to
be repetitive, a continuous waveform pattern is inherently visible on the
display.
But without a regular signal pattern, the oscilloscope requires controls to
determine what specific point in time (when a trigger is met) to show the
signal on the display. This is accomplished and affected in a variety of
ways.
Some trigger settings allow for pre-trigger, post-trigger, and a delay
between the time of the trigger event and the time when the display is
refreshed (or sweeped) and the waveform is again shown on the screen.
The instrument uses many waveform capture techniques that trigger on
features and conditions that you define. These triggers fall into the
following major categories:
Simple Triggers
– activated by basic waveform features or
conditions such as a positive or negative slope, and hold‐off
