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.
FFT RMS Performs a FFT RMS calculation on a signal. RMS is similar to FFT, however
the amplitude is calculated as RMS and not dB. Four types of FFT windows are
available: Hanning, Flattop, Rectangular, and Blackman.
