1. Select the sources with MORE ➞ Math1, Math2, or Math3 (main) ➞
Change Math waveform definition (side) ➞ Dual Wfm Math (main) ➞
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 measure
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.
