When you select 1*2, channel 1 and channel 2 voltage values are multiplied
point by point, and the result is displayed. 1 * 2 is useful for seeing power
relationships when one of the channels is proportional to the current.

Scale allows you to set your own vertical scale factors for multiply expressed
as V2/div (Volts-squared/division), A2/div (Amps-squared/division), or W/div

Press the Scale softkey, then turn the Entry knob to rescale 1 * 2.
Offset allows you to set your own offset for the multiply math function. The
offset value is in V2 (Volts-squared), A2 (Amps-squared), or W (Watts) and is
