3.2.10.2 Trace Control
The controls on this tab allow you to set the "Trace Type" on page 1927 and its
update mode.
There are four Trace Types:
–
Clear/Write
–
Trace Average
–
Max Hold
–
Min Hold
Each type handles data in a different way.
Each trace also has two values that determine whether it is being written or not, and
whether it is being displayed or not. These values, Update and Display, are
described fully in the "View/Blank" on page 1740 control description. Essentially,
when Update is ON, a trace is updating, and when Update is OFF it is not. When
Display is ON, it is visible and when Display is OFF it is not. These terms are used
throughout the descriptions in this section.
