DSA800 allows for up to four traces to be displayed at the same time, and each
trace has its own color (Trace 1 - Yellow, Trace 2 - purple, Trace 3 - light blue and
Trace 4 - green). All traces can be set freely except Trace 4 (a math operation trace
that can only be obtained using the other three traces).
Select Trace 1, Trace 2 or Trace 3 to set the corresponding parameters. The default
trace and type is Trace 1 and Clear Write.
Note: the trace currently displayed on the screen can be stored in internal or
external memory and can be recalled when needed. Press Storage to save the
trace according to the method introduced in “Storage”.

Power Avg and Freeze. The corresponding icon of the trace type will be displayed
in the status bar at the left of the screen. Take Trace 1 (yellow) as an example and
the icons are as shown in the figure below.
