5.17 Using Waveform Mathematics Functions
When adding (CH1 + CH2), subtracting (CH1
–
CH2, CH2
–
CH1), multiplying (CH1 * CH2) or
dividing
（
CH1 / CH2
）
the input waveforms of CHI and CH2, the Oscilloscope will display the
mathematical result waveform M and the input waveforms of CH1 and CH2 on the screen. The
Mathematics functions perform a point-to-point calculation on the waveforms CH1 and CH2.
To use a Mathematics function, do the following:
1.
Press
the
MENU
key and the function menu is displayed at the right side of the screen.
2.
Press the
MENU
▲
or
MENU
▼
key to select the
Waveform Calculation.
Five items
selectable appears at the bottom of the screen.
3.
Press
F3
key to select
CH1+CH2
and the calculated waveform M (green) appears on the
screen. Again, press the
F3
key to close Waveform Calculation.
4.
In this case, press the
OSC OPTION
key and the following is visible at the bottom left side
of the screen.
