Help Markers
Help Markers clarify parameter measurements by displaying movable
cursors and a visual representation of what is being measured. For the at
level parameters, Help Markers make it easier to see where your waveform
intersects the chosen level. This feature also displays the hysteresis band
that you have set about that level.
You also have the option, by means of an Always On checkbox, to leave the
Help Markers displayed after you have closed the Help Markers setup
dialog.
You have a choice of Simple or Detailed views of the markers:

The Simple selection produces cursors and Measure Gate gate posts.
The gate posts are independently placeable for each parameter.

The Detailed selection produces cursors, Measure Gate gate posts, a
label identifying the parameter being measured, and a level
indicator and hysteresis band for at level parameters (not part of
Standard Horizontal or Standard Vertical parameters).
