7.3 Make the Math Function Menu Setting
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.

Setting Description
CH1-CH2
CH1 waveform minus CH2 waveform.
CH2-CH1
CH2 waveform minus CH1 waveform
CH1+CH2
Add CH1 waveform into CH2 waveform.
CH1*CH2
Multiply CH1 waveform and CH2 waveform.
CH1/CH2
Divide CH1 waveform by CH2 waveform
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
