Math Waveforms
A scale unit of
U
(undefined) will be displayed for math functions when two source
channels are used and they are set to dissimilar units and the combination of units
cannot be resolved.
Math Operators
Math operators perform arithmetic operations (add, subtract, or multiply) on
analog input channels.

Add or Subtract
When you select add or subtract, the
Source 1
and
Source 2
values are added or
subtracted point by point, and the result is displayed.
You can use subtract to make a differential measurement or to compare two
waveforms.
If your waveforms' DC offsets are larger than the dynamic range of the
oscilloscope's input channels you will need to use a differential probe instead.
