Description of math functions
The WaveSurfer MXs-B oscilloscope contains several Math operators as standard,
plus an FFT function. Descriptions are provided as follows:
plus an FFT function. Descriptions are provided as follows:
Standard Math
Absolute Value – calculates the absolute value of a waveform.
Average – calculates either a summed or continuous average up to
1 million sweeps (user selectable).
1 million sweeps (user selectable).
Derivative – calculates the derivative of adjacent samples.
Difference (Subtract) – subtracts two waveforms.
Envelope – calculates highest and lowest vertical values of a
waveform at each horizontal value for a given number of
acquisitions (sweeps).
waveform at each horizontal value for a given number of
acquisitions (sweeps).
Enhanced Resolution (ERES) – noise reduction and smoothing
filter specified by number of additional bits.
filter specified by number of additional bits.
Fast Fourier Transform (FFT) – computes a power frequency
spectrum of an FFT with Rectangular, Von Hann, Flat Topp,
Hamming, Blackman-Harris, and Hanning windows, and capability

Math Operator.
Floor - calculates the lowest vertical values of a waveform at each
horizontal value for a given number of acquisitions (sweeps).
horizontal value for a given number of acquisitions (sweeps).
Integral – calculates the linearly rescaled integral (with multiplier
and adder) of a waveform input.
and adder) of a waveform input.
Invert – inverts the waveform.
Product (Multiply) – Multiplies two waveforms.
Ratio (Divide) – Calculates the ratio of two waveforms.
