of Math3 can be CH1-CH4, Ref1-Ref10, Math1, or Math2; the source of
Math4 can be CH1-CH4, Ref1-Ref10, Math1, Math2, or Math3; only the
channels that have been enabled currently can be selected.
⚫ Press Offset to set the vertical offset of the operation results. For setting
methods, refer to the descriptions in "Parameter Setting Method". You can
also directly rotate Wave Vertical POSITION or enable the touch screen
to adjust the vertical offset.
⚫ Press Scale to set the vertical scale of the operation results. For setting methods,
refer to the descriptions in "Parameter Setting Method". You can also
directly rotate Wave Vertical SCALE or enable the touch screen to adjust
the vertical scale.
⚫ Press More → AutoSetting to adjust the vertical scale and offset of the
operation results to the optimal value according to the current configuration, so
as to better observe.
⚫ Press More → Invert to enable or disable the inverted display function of the
waveform.
⚫ Press More → Expand to expand or compress the measurement waveform
around the "Center" or "GND".
⚫ Press More → Label to set the label for math operation results. For details,
refer to descriptions in "Math Operation Label".
⚫ Press More → Color Grade to enable or disable the color grade display of the
operation results. When enabled, different colors are displayed on the screen to
indicate the times of data acquisition or acquisition probability.
⚫ Press More → Reset ColorGrade to clear the color grade display and display
the color grade again.
FFT
FFT (Fast Fourier Transform) is used to transform time-domain signals to
frequency-domain components (frequency spectrum). MSO8000 oscilloscope
provides FFT operation function which enables you to observe the time-domain
waveform and spectrum of the signal at the same time. FFT operation can facilitate
the following works:
⚫ Measure harmonic components and distortion in the system;
⚫ Display the characteristics of the noise in DC power;
⚫ Analyze vibration.
Press Math → Math1 → Operator to select "FFT":
⚫ Press Operation continuously to enable or disable the FFT operation function.
When enabled, the operation results are displayed as purple waveforms on the
screen. At the same time, the parameters such as vertical scale, center
frequency, and resolution are displayed at the bottom of the screen, as shown in
