To perform transforms or filters on an arithmetic operation
To perform a transform function (see "Math Transforms" on page 78) or filter (see
"Math Filters" on page 94) on the add, subtract, or multiply arithmetic operations:
1 Press the Function softkey and select g(t): Internal.
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 or filter.
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.

Units for Math Waveforms
Units for each input channel can be set to Volts or Amps using the Units softkey in
the channel's Probe Menu. Units for math function waveforms are:
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.
