6.17 Using Waveform Mathematics Functions
When adding (CH1 + CH2), subtracting (CH1 – CH2, CH2 – CH1), multiplying (CH1 * CH2) or
dividing （CH1 / CH2） the input waveforms of CHI and CH2, the Oscilloscope will display the
mathematical result waveform M and the input waveforms of CH1 and CH2 on the screen. The
Mathematics functions perform a point-to-point calculation on the waveforms CH1 and CH2.
To use a Mathematics function, do the following:
1. Press the MENU key and the function menu is displayed at the right side of the screen.
2. Press the MENU ▲ or MENU ▼ key to select the Waveform Calculation. Five items
selectable appears at the bottom of the screen.
3. Press F3 key to select CH1+CH2 and the calculated waveform M (green) appears on the
screen. Again, press the F3 key to close Waveform Calculation.
4. In this case, press the OSC OPTION key and the following is visible at the bottom left side
of the screen.

Then, press the OSC ▲ or OSC ▼ key to adjust the vertical position of the calculated
waveform M displayed on the screen.
5. Press the OSC OPTION key and the following appears at the bottom left side of the
screen.
