In the MATH function, scopemeter calculates the addition, subtraction, multiplication, or division result of source
A and source B according your settings and shows it on the screen. An arrowhead with the character "M" in it
indicates the position of the MATH waveform.
As an usual function, FFT is mainly used to make harmonic wave analysis on waveform and determine communi-
cation malfunction or the quality of the power supply, and etc. The FFT interface is as Figure 10.

Description
Operation
A+B
Waveform addition of source A and source B
A-B
Waveform obtained by the subtracting the waveform of source B from
the waveform of source A.
A*B
Waveform obtained by the multiplying the waveform of source A by
the waveform of source B.
A/B
Waveform obtained by the dividing the waveform of source A by the
waveform of source B.
FFT
Fast Fourier Transform
Source A
CHA
To set waveform of channel A as source A.
CHB
To set waveform of channel B as source A.
Source B
CHA
To set waveform of channel A as source B.
CHB
To set waveform of channel B as source B.
Inverse
ON
Display mathematical operation waveform inversely.
OFF
Display mathematical operation waveform normally.
