The
WAVE MATH
functions in showing the result of adding, subtracting, multiplying or dividing calculation on
CH1 and CH2 channel waveforms. Also, the result of arithmetic operation can be measured with grid or
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 and steps in the 1-2-5 form, 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 with the
CHM ZERO
key used.
The corresponding operation function table

Description
CH1-CH2
Subtract CH2 from CH1
CH2-CH1
Subtract CH1 from CH2
CH1+CH2
Add CH2 to CH1
CH1xCH2
Multiply CH2 with CH1
CH1/CH2
Divide CH1 by CH2
To perform the
CH1+CH2
waveform calculation, do the following:
1. Press the
MENU
key and the function menu appears at the right of the screen.
2. Press the
MENU

or
MENU
▼
key to select
MATH
and 5 options are displayed at the bottom of the
screen.
3. Press the
F3
CH1+CH2 key and the obtained waveform M appears on the screen. Again, press the
F3
key and Close the waveform M.
4. Press
OPTION
and left bottom display as
- CHMath Volts/Div
- CHM Zero
Press
◄
(yellow) or

(yellow) to adjust the range of M waveform
Press
▲
(yellow) or
