When adding (CH1 + CH2), subtracting (CH1 – CH2, CH2 – CH1), multiplying (CH1 *
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 Mathematical functions perform a point-to-point calculation
on the waveforms (CH1 and CH2).
To use a Math function, perform the following steps:
1. Press the MENU key; the function menu will appear at the right side of the
screen.
2. Press MENU ▲ or MENU ▼ to select WAVE MATH. Five (5) selectable
options will appear at the bottom of the screen.
3. Press the F3 key to select CH1+CH2 ; the calculation resulting waveform M
(green) will then appear on the screen. Press the F3 key again to exit the
Waveform Calculation mode.
4. Press OPTION and the screen will show the following on the bottom left:
—CH Math Volts/Div
—CH M Zero
