Accumulate—waveform is not
erased between successive
acquisitions (persistence).
All displays are time-correlated,
so the trigger, x, and o markers
are located at equivalent posi-
tions in time on each display.
Overlay—multiple channels dis-
played on one line, with value in
selected base if space permits.
Maximum of 24 lines per screen;
may scroll through up to 96 lines.
Chart mode plots the value of a
specified label (on y-axis) versus
a state number or another label
(on x-axis). Both axes can be
scaled. Useful for A/D converters
and obtaining a visual overview
of bus activity (address flow or
data flow).
There are three SPA modes avail-
able: State Overview (shown here
provides a visual indication of
memory use), State Histogram (%
time spent in each function), and
Time Interval (execution time of a
particular function).
