2.6.3 Math Functions
Math shows the results after +,-,*, / and FFT operation of the CH1,CH2,CH3
and CH4.
Press the MATH button to display the waveform math operations. Press the MATH
button again to remove the math waveform display.

CHX and CHY.
CHX
Invert
on
off
Invert the CHX waveform.
Turn off CHX Invert function.
CHY
Invert
on
off
Invert the CHY waveform.
Turn off CHY Invert function.
Table 2-7 MATH function instruction
Operation Setting
Introduction
＋
CHX+CHY
CHX waveform adds CHY waveform.
CHX-CHY
The channel Y waveform is subtracted
from the channel X waveform.
－
CHY-CHX
The channel X waveform is subtracted
from the channel Y waveform.
*
CHX*CHY
Source X multiply source Y.
CHX/CHY
Source X divides Source Y.
/
CHY/CHX
Source Ydivides Source X.
FFT
Fast Fourier Transform.
CH1 waveform add CH2waveform, see picture 2-18:
Note:X,Y represent CH1,CH2,CH3 and CH4 respectively, but X and Y can’t represent the
same signal source.
