To perform a math function on an arithmetic operation
To perform an FFT or low-pass filter math function on an arithmetic operation
(add, subtract, or multiply):
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 an FFT or low-pass filter math function.
5 Press the Source 1 softkey and select g(t) as the source. Note that g(t) is only
available when you select an FFT or low-pass filter math function in the
previous step.
To adjust the math waveform scale and offset
Use the multiplexed scale and position knobs next to 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 Probe menu. Units for math function waveforms are:
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.
