Autoscale
Autoscale enables the vertical scale of the waveform plot and meter bar to be set automatically,
which can make it easier to keep the live signal(s) clearly visible in the plot. Sometimes, when
a signal doesn't appear as expected, setting Autoscale to Auto can solve the problem. When
autoscale is off, the vertical scale of the plot can be manually adjusted by a two-finger pinch
gesture within the axis label region of the waveform plot (the meter bar will be adjusted to
match).
Amplitude Scale
Tap on Amplitude Scale to select a vertical scale for the plot in units per division.
Autoscale will be turned off. Each selected
channel can have units assigned independent of other channels, so the scale will be set
independent of any specific units.
Waveform Time Scale
Here, the horizontal time scale of the waveform plot can be manually adjusted by selecting
the desired value. The horiztonal scale can also be manually adjusted by a two-finger pinch
gesture within the horizontal axis label region of the plot.
