Math Operations
The Math operations can add, subtract, multiply or perform
FFT/FFT RMS on the input waveforms. The resulted waveform can
be measured using the cursors, and saved or recalled just like
normal input signals.
Overview
Addition (+)
Adds the amplitude of CH1 & CH2 signals.
Subtraction (–)
Extracts the amplitude difference between CH1 &
CH2.
Multiplication (×)
Multiplies CH1 and CH2.
FFT
Performs a FFT calculation on a signal. Four types
of FFT windows are available: Hanning, Flattop,
Rectangular, and Blackman.
