Description of math functions

The WaveSurfer MXs-B oscilloscope contains several Math operators as standard,
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).

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).

Enhanced Resolution (ERES) – noise reduction and smoothing
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
to calculate up to 1 Mpts. Also allows FFT Averaging through use of
2

Floor - calculates the lowest vertical values of a waveform at each
horizontal value for a given number of acquisitions (sweeps).

Integral – calculates the linearly rescaled integral (with multiplier
and adder) of a waveform input.

Invert – inverts the waveform.

Product (Multiply) – Multiplies two waveforms.

Ratio (Divide) – Calculates the ratio of two waveforms.
