UNCTION
The WAVE MATH functions show the calculation results (adding, subtracting,
multiplying or dividing CH1 and CH2 channel waveforms). Arithmetic operation
results can be displayed using a grid or a cursor. The amplitude of the calculated
waveform can be adjusted with CHM VOL, which is displayed in the scale factor
form. The amplitude ranges from 0.001 through 10 (in 1, 2, and 5 step increments)
that is, it can be expressed as 0.001X, 0.002X, 0.005X...10X. The position of the
calculated waveform can be adjusted up and down using the CHM ZERO key.

Description
CH1-CH2
CH1 waveform minus CH2 waveform
CH2-CH1
CH2 waveform minus CH1 waveform
CH1+CH2
Add CH1 waveform to CH2 waveform
CH1*CH2
Multiply CH1 and CH2 waveforms
CH1/CH2
Divide CH1 by CH2
To perform a CH1+CH2 waveform calculation, perform the following:
1.
Press the MENU key; the function menu will appear at the right of the screen.
2.
Press MENU ▲ or MENU ▼ to select WAVE MATH. Five (5) selectable options will
then be displayed at the bottom of the screen.
3.
Press the F3 CH1+CH2 key and waveform M appears on the screen. Press the F3
key again to close waveform M.
4.
Press OPTION and the display will show the following:
— CH Math Volts/Div
— CH M Zero
