4 Math Waveforms
2 If f(t) is not already shown on the Function softkey, press the Function sofkey and
select f(t): Displayed.
3 Use the Operator softkey to select an operator or transform.
For more information on the operators or transforms, see:
• “Math Operators" on page 74
• “Math Transforms" on page 76
4 Use the Source 1 softkey to select the analog channel on which to perform
math. You can rotate the Entry knob or repetitively press the Source 1 softkey to
make your selection. If you choose a transform function (FFT) the result is
displayed.
5 If you select an arithmetic operator, use the Source 2 softkey to select the
second source for the arithmetic operation. The result is displayed.
6 To re-size and re-position the math waveform, see “To adjust the math
waveform scale and offset" on page 73.
To perform a transform function on an arithmetic operation
To perform a transform function (FFT) 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 a transform function (FFT).
Math Operating Hints
If the analog channel or math function is clipped (not fully displayed on screen) the resulting
displayed math function will also be clipped.
Once the function is displayed, the analog channel(s) may be turned off for better viewing of
the math waveform.
The vertical scaling and offset of each math function can be adjusted for ease of viewing and
measurement considerations.
The math function waveform can be measured using [Cursors] and/or [Meas].
