2 Use the Operator, Source 1, and Source 2 softkeys to set up an arithmetic
operation.
3 Press the Function softkey and select f(t): Displayed.
4 Use the Operator softkey to select a transform function (FFT).
5 Press the Source 1 softkey and select g(t) as the source. Note that g(t) is
only available when you select a transform function in the previous
step.
To adjust the math waveform scale and offset
1 Make sure the multiplexed scale and position knobs to the right of the
[Math] key are selected for the math waveform.
If the arrow to the left of the [Math] key is not illuminated, press the
key.
2 Use the multiplexed scale and position knobs just to the right of the
[Math] key to re-size and re- position the math waveform.

Multiply
When you select the multiply math function, the Source 1 and Source 2
values are multiplied point by point, and the result is displayed.
Multiply is useful for seeing power relationships when one of the channels
is proportional to the current.
NOTE
Math Scale and Offset are Set Automatically
Any time the currently displayed math function definition is changed, the function is
automatically scaled for optimum vertical scale and offset. If you manually set scale and
offset for a function, select a new function, then select the original function, the original
function will be automatically rescaled.
