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
nd
Math Operator.
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.
