Digital channel voltage measurements
Automatic voltage measurements are not valid on digital channels on the
mixed-signal oscilloscope.
Amplitude
The Amplitude of a waveform is the difference between its
Top and Base values. The Y cursors show the values being
measured.
Average
Average is the sum of the waveform samples divided by the
number of samples over one or more full periods. If less
than one period is displayed, Average is calculated on the
full width of the display. The X cursors show what portion
of the displayed waveform is being measured.

Base
The Base of a waveform is the mode (most common value)
of the lower part of the waveform, or if the mode is not well
defined, the base is the same as Minimum. The Y cursor
shows the value being measured.
Maximum
Maximum is the highest value in the waveform display. The
Y cursor shows the value being measured.
Minimum
Minimum is the lowest value in the waveform display. The Y
cursor shows the value being measured.
