3-4. Math Operation
3-4-1. Overview
Background
Math operation runs addition, subtraction,
multiplication, division, FFT, or certain advanced
math functions for waveform manipulations using
the input signals or reference waveforms (Ref1~4)
and shows the result on the display. The resulted
waveform characteristics can be measured using
the cursors.
Addition (+)
Adds the amplitude of two signals.
Source
CH1~4, Ref1~4
Subtraction (
–) Extracts the amplitude difference between two
signals.
Source
CH1~4, Ref1~4
Multiplication (×) Multiplies the amplitude of two signals.
Source
CH1~4, Ref1~4
Division (÷)
Divides the amplitude of two signals.
Source
CH1~4, Ref1~4
FFT
Runs FFT calculations on a signal. Four types of
FFT windows are available: Hanning, Hamming,
Rectangular, and Blackman.
Source
