During Autoscale, the delay is set to 0.0 seconds, the Time/Div setting is a
function of the input signal (about 2 periods of the triggered signal on the
screen), and the triggering mode is set to edge. The instrument stays in
Normal or Peak Detect display mode, depending on what was selected when
Autoscale was performed. Vectors remain in the state they were before the
Autoscale.
Autoscale sets the trigger to a rising edge on a channel, checking the
channels in this priority: A2, A1, D15...D0.

The Undo Autoscale function returns the instrument to the setup that
