To perform a math function upon an arithmetic operation
To perform a function (differentiate, integrate, FFT, or square root) 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 function (differential, integral, FFT,
or square root).
5 Press the Source 1 softkey and select g(t) as the source. Note that g(t) is
only available when you select a function in the previous step.
Math scale and offset
Any math function may be manually scaled by pressing the Scale or Offset
softkeys and adjusting the value.
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].
