5.16. Using Waveform Mathematics Functions
When adding (CH1 + CH2), subtracting (CH1 – CH2, CH2 – CH1), multiplying (CH1 x CH2) or dividing
(CH1 / CH2) the input waveforms of CH1 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. Press OPTION and left bottom display as
- CHMath Volts/Div
- CHM Zero
5. Then, press ▲ (yellow) or ▼ (yellow) to adjust vertical display position of waveform M. Press ◄ (yellow)
or ► (yellow) to adjust display times factor of waveform M.
Now, you can see a screen that looks like the following Figure.
