3. Press Set Function to (side) repeatedly to cycle it to inv (invert), intg, or
diff. Waveform integration (intg) is described on page 3–165, and waveform
differentiation (diff) is described on page 3–161.
4. To create the math waveform, press OK Create Math Wfm (side).
To create a math waveform that requires two waveform sources, do the following
steps:
1. Press MORE ➞ Math1, Math2, or Math3 (main) ➞ Change Math
waveform definition (side) ➞ Dual Wfm Math (main).
2. To define the first source waveform, press Set 1st Source to (side) repeated-
ly to cycle it to the desired channel or reference waveform.
3. To define the second source waveform, press Set 2nd Source to (side)
repeatedly to cycle it to the desired channel or reference waveform.
4. To enter the math operator, press Set operator to (side) repeatedly to cycle it
through the choices. Supported operators are +, –, * and /.
NOTE. If you select *, for multiply, in step 4, the cursor feature will measure
amplitude in the units volts squared, VV, rather than in volts, V.
