Set 1st Source to and Set 2nd Source to (side). Enter the sources by
repeatedly pressing the appropriate channel selection button.
2. To enter the math operator, press Set operator to (side) to cycle
through the choices. Supported operators are +, -, * and /.
3. Press OK Create Math Wfm (side) to perform the function.
NOTE
If you select *, for multiply, in step 2, the cursor feature will meaĆ
sure amplitude in the units volts squared VV rather than in volts V.
If your oscilloscope is equipped with Advanced DSP Math, you can also
create integrated, differentiated, and Fast Fourier Transform waveforms. See
Fast Fourier Transforms on page 3Ć36, Waveform Integration on page 3Ć139,
and Waveform Differentiation on page 3Ć143.
