Orange, dashed lines show at the
Span Start
and
Span Stop
locations. The trace is zoomed so that the span section fills the
screen.
The launch compensation markers never show with the
Span
Start
and
Span Stop
markers because you must turn off launch
compensation to use the span function.

Measurements for events in the span show in green if the
event passed, red if the event failed, or black is there is no
limit for measurement.
Measurements for events outside of the span show in blue.
