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.

1 In the Waveform Math Menu, press the Scale or Offset sofkeys to set your own scale

factors (units/division) or offset (units) for the selected math function. The Function

softkey must be set to f(t): Displayed in order to set scale and offset.

2 Press the Scale or Offset softkey, then turn the Entry knob to rescale or change the

offset value for your math function.

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 [Quick Meas].

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.
