Math Operation
Overview
Background
Math operation runs addition, subtraction,
multiplication, or FFT using the input signals and
shows the result on the display. The resulted
waveform characteristics can be measured using
the cursors.
Addition (+)
Adds amplitude of two signals.
Channel pairs
Channel 1 + 2, 3 + 4
Subtraction (–)
Extracts the amplitude difference between two
signals.
Channel pairs
Channel 1 – 2, 3 – 4
Multiplication (*)
Multiplies amplitude of two signals.
Channel pairs
Channel 1 * 2, 3 * 4
FFT
Runs FFT calculation on a signal. Four types of
FFT windows are available: Hanning, Flattop,
Rectangular, and Blackman.
Channel
Channel 1, 2, 3, 4
FFT rms
Runs FFT rms calculation on a signal. Four types of
FFT windows are available: Hanning, Flattop,
Rectangular, and Blackman.
Channel
Channel 1, 2, 3, 4
