The
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.

Description
CH1-CH2
CH1 waveform minus CH2 waveform.
CH2-CH1
CH1 waveform minus CH2 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 UP or MENU DOWN key to select MATH and 5 options are displayed at
the bottom of the screen.
